What i want to achieve is:
Have a Master Grid. Clicking on a row of this grid, i want to filter the rows of the ChildGrid.
What i have done so far:
function updateChildGridRows(field, operator, value) {
// get the kendoGrid element.
var gridData = $("#childGrid").data("kendoGrid");
var filterField = field;
var filterValue = value;
// get currently applied filters from the Grid.
var currFilterObj = gridData.dataSource.filter();
// if the oject we obtained above is null/undefined, set this to an empty array
var currentFilters = currFilterObj ? currFilterObj.filters : [];
// iterate over current filters array. if a filter for "filterField" is already
// defined, remove it from the array
// once an entry is removed, we stop looking at the rest of the array.
if (currentFilters && currentFilters.length > 0) {
for (var i = 0; i < currentFilters.length; i++) {
if (currentFilters[i].field == filterField) {
currentFilters.splice(i, 1);
break;
}
}
}
if (filterValue != "") {
currentFilters.push({
field: filterField,
operator: "eq",
value: filterValue
});
}
gridData.dataSource.filter({
filters: currentFilters
}); }
I got this code from the following jsfiddle:
http://jsfiddle.net/randombw/27hTK/
I have attached the MasterGrid's Change event to MasterGridSelectionChange() method. From there i am calling my filter method.
But when i click on the MasterGrid's row, all of the rows in my ChildGrid are getting removed.
One thing i can understand is, if i give wrong column name in the filter list, all the rows will be removed. But even though i have given correct ColumnName, my rows are getting deleted.
Sorry for the long post.
Please help me with this issue, as i am stuck with this for almost 4 days!
Thanks.
You can define ClientDetailTemplateId for the master grid and ToClientTemplate() for the Child grid
read Grid Hierarchy for a example
This is my first time working with Kendo UI. I have a Kendo UI grid with child nodes. I want to retain the expanded rows after databinding. Right now its getting collapsed after a row is added in the child
I have tried suggestion from here
dataBound: function() {
this.expandRow(this.tbody.find("tr.k-master-row").first());
}
But this expands the first row only.
How to retain rows? What am I missing?
Codepen
After a lot of playing around with your code example in CodePen, I believe I've come up with an elegant solution that works.
Having worked with Kendo UI for over three years, I've become pretty familiar with some of its inner workings. As such, I'm going to take advantage of one of these - the data-uid attribute. Kendo UI puts these on all <tr> elements in its grid. I chose this attribute because I know that when we call grid.expandRow() we're going to need to fashion a valid jQuery selector to pass in as a parameter. This eliminates the need for us to add our own attributes or classes and the code to handle them.
First, we need to define a variable to hold our row reference. We'll call it expandedRowUid. To set its value, we hook into the detailExpand event of the grid. So, when the user expands a row, we store its data-uid number.
var expandedRowUid;
var grid = $('#grid').kendoGird({
// ...
detailExpand: function(e) {
expandedRowUid = e.masterRow.data('uid');
}
});
Then, whenever a change is made that causes the master grid to re-bind to its data, we hook into the dataBound event of the grid and re-expand the row that has a data-uid equal to the one stored in expandedRowUid.
var grid = $('#grid').kendoGird({
// ...
detailExpand: function(e) {
expandedRowUid = e.masterRow.data('uid');
},
dataBound: function() {
this.expandRow($('tr[data-uid=' + expandedRowUid + ']'));
}
});
Here is the working CodePen example.
NOTE: This will only re-expand the last row that was expanded before the data bind is triggered. So, if you expand rows 4, 5, and 2 in that order, and then trigger a data bind, only row 2 will be re-expanded. You can obviously extend this functionality to handle use cases like that though.
GridDetailExpand: function (e) {
var gridId = e.sender.element[0].id;
var grid = $("#" + gridId).data("kendoGrid");
var data = grid.dataItem(e.masterRow);
addToArray(expandedRows, data.UniqueIdOfYourDataInGrid);
},
GridDetailCollapse: function (e) {
var gridId = e.sender.element[0].id;
var grid = $("#" + gridId).data("kendoGrid");
var data = grid.dataItem(e.masterRow);
removeFromArray(expandedRows, data.UniqueIdOfYourDataInGrid);
}
And then on databound
var gridId = e.sender.element[0].id;
var grid = $("#" + gridId).data("kendoGrid");
$.each(grid.tbody.find('tr.k-master-row'), function () {
var data = grid.dataItem(this);
if (isInArray(expandedRows, data.UniqueIdOfYourDataInGrid)) {
grid.expandRow(this);
}
});
Functions required:
var expandedRows = [];
function addToArray(arr, value) {
for (var i = 0; i < arr.length; i++) {
if (arr[i] === value) return;
}
arr.push(value);
}
function removeFromArray(arr, value) {
for (var i = 0; i < arr.length; i++) {
if (arr[i] === value) {
delete arr[i];
return;
}
}
}
function isInArray(arr, value) {
for (var i = 0; i < arr.length; i++) {
if (arr[i] === value) return true;
}
return false;
}
Hope this helps ... took me a while to figure it out...
Solution for Retaining Last Expanding row in the parent grid after records added in the child grid get refreshed.
detailInit: function (e) {
//Get Parent Grid Last expanded Row index
lastRowIndex = $(e.masterRow).index(".k-master-row");
},
dataBound: function () {
//Check any parent grid row is expanded based on row index
if (lastRowIndex != null && lastRowIndex != undefined){
//find the Grid row details based on row index
var row = $(this.tbody).find("tr.k-master-row:eq(" + lastRowIndex + ")");
//If expand Row exists then it will expanded
this.expandRow(row);
}
else {
//None of the Parent Grid row is expanded then,default First row is expanded
this.expandRow(this.tbody.find("tr.k-master-row").first());
}
}
is there an example of using jqgrid's getChangedCells
method to determine if data has changed?
I grepped getChangedCells in the downloadable demos for
jqgrid, and could only find the function definition, not
example usages of getChangedCells.
What I want to do is save the edits that a user's
made if the user clicks on another row. But, I only
want to submit the save if the row is dirty.
Thanks in advance,
--Nate
There are no safe dirty flag on the row. You can use the fact that at the beginning of row editing (at the start of the inline editing mode) the method editRow add editable="1" attribute to the grid row (<tr> element). Later the methods saveRow and restoreRow changes the attribute value to editable="0". So the rows of the current page which was at least once in the inline editing mode will have the editable attribute. If the id of the table element is "list" you can find the edited rows with
$("#list tr[editable]")
The ids of the elements of the set are the rowids of the rows.
If you use paging in the grid you should be careful and save the ids of the edited rows on the current page before the changing of the page. The onPaging event would help you here.
In my opinion the best and the most safe way to do what you need is to use aftersavefunc parameter of the editRow or saveRow methods (probably you use directly only editRow). Inside of your aftersavefunc function you can save the id of the modified row in an array/map. This will solve your problem and will safe work.
Finally, I managed to bring a piece of code to detect what we want ;)
Hopefully any jqgrid gurus there (like Oleg), have enough time to review this code and improve it.
The example code will work for detect data changed in a grid with an editable field named "name". If you want to check for changed data in more columns, you have to add the variables after_edit and before_edit asociated with that columns.
To get the previous cell data inside the onSelectRow function, I don't used the getCell method because in the documentation says in red:
Do not use this method when you editing the row or
cell. This will return the cell content and not the
actuall value of the input element
By disgrace I could check that the documentation was right :(.
However the getCell function works properly with the current cell data.
And here is the code:
// Declare variables used for inline edit functionality.
var last_selected;
var before_edit_value;
var after_edit_value;
$('#grid-id').jqGrid({
...
onSelectRow: function(row_id){
if(row_id && row_id !== last_selected) {
/*
* Determine if the value was changed, if not there is no need to save to server.
*/
if (typeof(last_selected) != 'undefined') {
after_edit_value = $('#grid-id tr#' + last_selected + ' .name_column input').val();
}
if (before_edit_value != after_edit_value) {
/*
* Save row.
*/
$('#grid-id').jqGrid(
'saveRow',
last_selected,
function(response){
/* SuccessFunction: Do something with the server response */
return true;
},
'http://url.to.server-side.script.com/server-side-script.php',
{
additional_data: 'example: additional string',
});
}
else {
/*
* Restore the row.
*/
$('#grid-id').jqGrid('restoreRow', last_selected);
}
before_edit_value = $('#grid-id').jqGrid('getCell', row_id, 'name');
}
last_selected = row_id;
/*
* Edit row.
*/
$('#grid-id').jqGrid(
'editRow',
row_id,
true,
function() {/* OnEditFunction */},
function(response) {
/* SuccessFunction: Do something with the server response */
return true;
},
'http://url.to.server-side.script.com/server-side-script.php',
{
additional_data: 'example: additional string',
});
},
...
});
In one of my projects I did the following: before editing the row I remember row data in global variable and after editing is done just check if row data was changed. Something like this (edit mode activated by double click):
var beforeEditData;
function onGridDblClickRow(id) {
if (isRowEditable(id)) {
beforeEditData = grid.getRowData(id);
grid.editRow(id, true, null, null, 'clientArray', null, onRowAfterEdit);
...
}
}
function onRowAfterEdit(row) {
var data = grid.getRowData(row);
if (!isDataChanged(beforeEditData, data)) {
return; // No changes
}
... // Save data here
}
function isDataChanged(before, after){
... // Allows tricky logic for dirty data, e.g. one may trim spaces etc.
}
Using MVC4 and JQuery this is what I did
In the View
<script type="text/javascript">
var $grid = $("#Grid");
var lastSelection;
var datachanged = false;
function gridInitialised() {
var headers = $('th>div>:input');
for (var h = 0; h < headers.length; headers[h++].onclick = (function () { if (datachanged) { $grid.saveRow(lastSelection); datachanged = false; } }));
}
function editRow(id) {
if (id && id !== lastSelection) {
if (datachanged) { $grid.saveRow(lastSelection); datachanged = false; }
$grid.restoreRow(lastSelection);
$grid.editRow(id, true);
var inputs = $('#'+id+'>td>:input[class="editable"]');
for (var i = 0; i < inputs.length; inputs[i++].onchange = (function () { datachanged = true; }));
lastSelection = id;
}
}
</script>
#Html.Trirand().JQGrid(Model.Grid, "Grid")
in the Model
Grid.ClientSideEvents.RowSelect = "editRow";
Grid.ClientSideEvents.GridInitialized = "gridInitialised";
The gridInitialised code is to handle changes to the search filter.

As Oleg mentioned 5 (wow) years ago - I used the saveRow function and passed the flag as extraparam.
something like this, assuming your "model" or a hidden column IsDirty in my case:
onSelectRow: function(id) {
if (id && id !== lastgridsel) {
$("#myGrid").saveRow(lastgridsel, false, "clientArray", { IsDirty: "True" });
$("#myGrid").editRow(id, true, null, null, "clientArray");
lastgridsel = id;
}
},
and then loop through the rows on Save click (external button in my case), something along the lines of:
$("#gridSaveBtn").on("click", function() {
var batch = new Array();
var dataIds = $("#myGrid").jqGrid("getDataIDs");
for (var i = 0; i < dataIds.length; i++) {
try {
$("#myGrid").jqGrid("saveRow", dataIds[i], false, "clientArray");
//get row data
var data = $("#myGrid").jqGrid("getRowData", dataIds[i]);
if (data["IsDirty"] === "True") {
batch.push(data);
}
} catch (ex) {
alert(ex.Message);
$("#myGrid").jqGrid("restoreRow", dataIds[i]);
}
}
});
I've got a jqGrid where I need to change the model after the data is loaded, but before it's parsed into the grid. In otherwords, I think I want to do it in the loadComplete handler. I see this approach: Setting JqGrid's colName and colModel from JSON data, but I'm have a bunch of grids already written that use the "load data with jqGrid" approach, rather than the "pre-load data and pass it to jqGrid" one used there, and I'm hoping to avoid re-coding, or making this one different.
(Hiding and showing hidden columns isn't practical, either.)
Is this possible?
More details:
Basically, I don't know what columns I need till I see the data. Say I'm showing traffic by state:
Date CA WA NY MN
4/20 100 90 85 72
4/21 95 85 89 70
There's only room to show four states, but there might be many more in the data (or there might be fewer), so I want them listed in order of traffic. Right now, the data is coming in like:
{
date : 4-20,
ca : 100,
wa : 90,
ny : 85,
mn : 72
hi : 56,
il : 30
},
{
date : 4-21,
ca : 95,
wa : 85, // note: for a given row, a column might be relatively lower
ny : 89, // than another. The column order is based on the overall
mn : 70
hi : 60,
il : 45
}
or it could be:
{
date : 4-20,
ny : 110,
hi : 95,
il : 90,
wa : 80
}
I've tried setting up columns like state1, state2, state3, state4 and then using jsonmap to remap them, but it didn't work.
loadonce = true, datatype = json
I found one way which seems work OK.
The idea of my solution is following. You use colModel having many hidden columns with the dummy names like 'cm0', 'cm1', 'cm2', ... All the columns has the same data like you need in your case. To fill the data more easy I use column templates existing since jqGrid 3.8.2:
var mygrid=jQuery("#list"),
cmIntTemplate = {
width:50,
sorttype:"int",
formatter:"integer",
align:"right",
hidden:true
},
cm = [
// here we define the first columns which we always has
// the list can be empty or has some columns with
// the properties other as the rest (without cmIntTemplate)
{name:"date",label:"Date",key:true,width:100, fixed:true,
formatter:'date',formatoptions:{srcformat:"m-d",newformat:"m/d"}}
], maxCol = 30, dummyColumnNamePrefix = "cm";
// Add dummy hidden columns. All the columns has the same template
for (i=0;i<maxCol;i++) {
cm.push({name:dummyColumnNamePrefix+i,template:cmIntTemplate});
}
After that I create jqGrid in the standard way, but with the jsonReader which use the page as function:
jsonReader: {
repeatitems: false,
page: function (obj) {
// ------------------------
// here I add the main code
// ------------------------
return obj.page;
}
}
The function from the jsonReader.page return the same value like as do default jsonReader, but I use the way with function because the function will be called directly before the reading of the main contain of JSON data. Inside of the code I get the first row of the data and use it's property names to fill jsonmap property of the corresponding column and set the column name. Additionally I make some dummy columns needed to display all the JSON data visible and the rest dummy column hidden. The last thing which should be done is correction of the grid width which was calculated previously. So the grid will look like this:
or like this
depend on the JSON input data.
The code of the page function is following:
page: function (obj) {
var rows = obj.rows, colModel = mygrid[0].p.colModel,
cmi, iFirstDummy, firstRow, prop,
orgShrinkToFit, isFound,
showColNames = [], hideColNames = [];
if (typeof(rows) === "undefined" || !$.isArray(rows) || rows.length === 0) {
// something wrong need return
return obj.page;
}
// find the index of the first dummy column
// in the colModel. If we use rownumbers:true,
// multiselect:true or subGrid:true additional
// columns will be inserted at the begining
// of the colModel
iFirstDummy = -1;
for(i=0;i<colModel.length;i++) {
cmi = colModel[i];
if (dummyTestRegex.test(cmi.name)) {
iFirstDummy = i;
break;
}
}
if (iFirstDummy === -1) {
// something wrong need return
return obj.page;
}
orgShrinkToFit = clearShrinkToFit();
// we get the first row of the JSON data
firstRow = rows[0];
for (prop in firstRow) {
if (firstRow.hasOwnProperty(prop)) {
// we will use the properties name of the first row
// as the names of the column headers of the grid
// find column index having prop as the name
isFound = false;
for(i=0;i<colModel.length;i++) {
cmi = colModel[i];
if (cmi.name === prop) {
isFound = true;
showColNames.push(prop);
break;
}
}
if(!isFound) {
// labels defines the column names
cmi = colModel[iFirstDummy];
showColNames.push(cmi.name);
mygrid.jqGrid('setLabel',cmi.name,prop);
// because of bug in jqGrid with calculation of width
// we have to reset the width
cmi.width = cmIntTemplate.width;
// we set jsonmap which jqGrid will use instead
// of dummy column names to read all row data
cmi.jsonmap = prop;
iFirstDummy++;
}
}
}
// fill the list of unused columns
for(i=0;i<colModel.length;i++) {
cmi = colModel[i];
if ($.inArray(cmi.name, showColNames) === -1 && dummyTestRegex.test(cmi.name)) {
hideColNames.push(cmi.name);
}
}
mygrid.jqGrid('showCol',showColNames);
mygrid.jqGrid('hideCol',hideColNames);
setGridWidthAndRestoreShrinkToFit(orgShrinkToFit);
return obj.page;
}
Inside of the page function I use small helper functions
var clearShrinkToFit = function() {
// save the original value of shrinkToFit
var orgShrinkToFit = mygrid.jqGrid('getGridParam','shrinkToFit');
// set shrinkToFit:false to prevent shrinking
// the grid columns after its showing or hiding
mygrid.jqGrid('setGridParam',{shrinkToFit:false});
return orgShrinkToFit;
},
setGridWidthAndRestoreShrinkToFit = function(orgShrinkToFit) {
// calculate the new grid width
var width=0, i=0, headers=mygrid[0].grid.headers, l=headers.length;
for (;i<l; i++) {
var th = headers[i].el;
if (th.style.display !== "none") {
width += $(th).outerWidth();
}
}
// restore the original value of shrinkToFit
mygrid.jqGrid('setGridParam',{shrinkToFit:orgShrinkToFit});
// set the grid width
mygrid.jqGrid('setGridWidth',width);
},
dummyTestRegex = new RegExp(dummyColumnNamePrefix+"(\\d)+");
The working demo you can see here.
UPDATED: Another answer with the demo shows how to create the grid which has another format of input data: [[], [], ...] (array of arrays) - matrix.
How to get a jqGrid cell value when in-line editing (getcell and getRowData returns the cell content and not the actuall value of the input element).
General function to get value of cell with given row id and cell id
Create in your js code function:
function getCellValue(rowId, cellId) {
var cell = jQuery('#' + rowId + '_' + cellId);
var val = cell.val();
return val;
}
Example of use:
var clientId = getCellValue(15, 'clientId');
Dodgy, but works.
Here is an example of basic solution with a user function.
ondblClickRow: function(rowid) {
var cont = $('#grid').getCell(rowid, 'MyCol');
var val = getCellValue(cont);
}
...
function getCellValue(content) {
var k1 = content.indexOf(' value=', 0);
var k2 = content.indexOf(' name=', k1);
var val = '';
if (k1 > 0) {
val = content.substr(k1 + 7, k2 - k1 - 6);
}
return val;
}
After many hours grief I found this to be the simplest solution. Call this before fetching the row data:
$('#yourgrid').jqGrid("editCell", 0, 0, false);
It will save any current edit and will not throw if there are no rows in the grid.
As you stated, according to the jqGrid documentation for getCell and getRowData:
Do not use this method when you editing the row or cell. This will return the cell content and not the actual value of the input element
Since neither of these methods will return your data directly, you would have to use them to return the cell content itself and then parse it, perhaps using jQuery. It would be nice if a future version of jqGrid could provide a means to do some of this parsing itself, and/or provide an API to make it more straightforward. But on the other hand is this really a use case that comes up that often?
Alternatively, if you can explain your original problem in more detail there may be other options.
Try this, it will give you particular column's value
onSelectRow: function(id) {
var rowData = jQuery(this).getRowData(id);
var temp= rowData['name'];//replace name with you column
alert(temp);
}
Basically, you have to save the row before you access the cell contents.
If you do, then you get the value for the cell instead of the markup that comes when the cell is in edit mode.
jQuery.each(selectedRows, function(index, foodId) {
// save the row on the grid in 'client array', I.E. without a server post
$("#favoritesTable").saveRow(foodId, false, 'clientArray');
// longhand, get grid row based on the id
var gridRow = $("#favoritesTable").getRowData(foodId);
// reference the value from the editable cell
foodData += foodId + ":" + gridRow['ServingsConsumed'] + ',';
});
Hi， I met this problem too. Finally I solved this problem by jQuery. But the answer is related to the grid itself, not a common one. Hope it helps.
My solution like this:
var userIDContent = $("#grid").getCell(id,"userID"); // Use getCell to get the content
//alert("userID:" +userID); // you can see the content here.
//Use jQuery to create this element and then get the required value.
var userID = $(userIDContent).val(); // var userID = $(userIDContent).attr('attrName');
you can use this directly....
onCellSelect: function(rowid,iCol,cellcontent,e) {
alert(cellcontent);
}
This is my solution:
function getDataLine(grida, rowid){ //vykradeno z inineeditu a vohackovano
if(grida.lastIndexOf("#", 0) === 0){
grida = $(grida);
}else{
grida = $("#"+grida);
}
var nm, tmp={}, tmp2={}, tmp3= {}, editable, fr, cv, ind;
ind = grida.jqGrid("getInd",rowid,true);
if(ind === false) {return success;}
editable = $(ind).attr("editable");
if (editable==="1") {
var cm;
var colModel = grida.jqGrid("getGridParam","colModel") ;
$("td",ind).each(function(i) {
// cm = $('#mygrid').p.colModel[i];
cm = colModel[i];
nm = cm.name;
if ( nm != 'cb' && nm != 'subgrid' && cm.editable===true && nm != 'rn' && !$(this).hasClass('not-editable-cell')) {
switch (cm.edittype) {
case "checkbox":
var cbv = ["Yes","No"];
if(cm.editoptions ) {
cbv = cm.editoptions.value.split(":");
}
tmp[nm]= $("input",this).is(":checked") ? cbv[0] : cbv[1];
break;
case 'text':
case 'password':
case 'textarea':
case "button" :
tmp[nm]=$("input, textarea",this).val();
break;
case 'select':
if(!cm.editoptions.multiple) {
tmp[nm] = $("select option:selected",this).val();
tmp2[nm] = $("select option:selected", this).text();
} else {
var sel = $("select",this), selectedText = [];
tmp[nm] = $(sel).val();
if(tmp[nm]) { tmp[nm]= tmp[nm].join(","); } else { tmp[nm] =""; }
$("select option:selected",this).each(
function(i,selected){
selectedText[i] = $(selected).text();
}
);
tmp2[nm] = selectedText.join(",");
}
if(cm.formatter && cm.formatter == 'select') { tmp2={}; }
break;
}
}
});
}
return tmp;
}
I have a solution:
1. Using this.value to get the current editing value in the editing row.
2. Save the cell value to a hidden field when the cell lost its focus.
3. Read the hidden field when you need.
The code:
colModel="[
{ name: 'Net', index: 'Net', editable:true, editoptions: { dataEvents: [ { type: 'focusout', fn: function(e) {$('#HiddenNet').val(this.value);} }] }, editrules:{custom:true,}},
{ name: 'Tax', index: 'Tax', editable:true, editoptions: { dataEvents: [ { type: 'focus', fn: function(e) {this.value=$('#HiddenNet').val(); } }] }, editrules:{custom:true}}
]"
Good Luck
You can get it from the following way...!!
var rowId =$("#list").jqGrid('getGridParam','selrow');
var rowData = jQuery("#list").getRowData(rowId);
var colData = rowData['UserId']; // perticuler Column name of jqgrid that you want to access
In my case the contents of my cell is HTML as result of a formatter. I want the value inside anchor tag. By fetching the cell contents and then creating an element out of the html via jQuery I am able to then access the raw value by calling .text() on my newly created element.
var cellContents = grid.getCell(rowid, 'ColNameHere');
console.log($(cellContents));
//in my case logs <h3>The Value I'm After</h3>
var cellRawValue = $(cellContents).text();
console.log(cellRawValue); //outputs "The Value I'm After!"
my answer is based on #LLQ answer, but since in my case my cellContents isn't an input I needed to use .text() instead of .val() to access the raw value so I thought I'd post this in case anyone else is looking for a way to access the raw value of a formatted jqGrid cell.
its very simple write code in you grid.php and pass the value to an other page.php
in this way you can get other column cell vaue
but any one can make a like window.open(path to pass value....) in fancy box or clor box?
$custom = <<<CUSTOM
jQuery("#getselected").click(function(){
var selr = jQuery('#grid').jqGrid('getGridParam','selrow');
var kelr = jQuery('#grid').jqGrid('getCell', selr, 'stu_regno');
var belr = jQuery('#grid').jqGrid('getCell', selr, 'stu_school');
if(selr)
window.open('editcustomer.php?id='+(selr), '_Self');
else alert("No selected row");
return false;
});
CUSTOM;
$grid->setJSCode($custom);
I think an extension of this would get it for you.
retrieving-original-row-data-from-jqgrid
I think a better solution than using getCell which as you know returns some html when in edit mode is to use jquery to access the fields directly. The problem with trying to parse like you are doing is that it will only work for input fields (not things like select), and it won't work if you have done some customizations to the input fields. The following will work with inputs and select elements and is only one line of code.
ondblClickRow: function(rowid) {
var val = $('#' + rowid + '_MyCol').val();
}
I've got a rather indirect way. Your data should have an unique id.
First, setting a formatter
$.extend(true, $.fn.fmatter, {
numdata: function(cellvalue, options, rowdata){
return '<span class="numData" data-num="'+rowdata.num+'">'+rowdata.num+'</span>';
}
});
Use this formatter in ColModel. To retrieve ID (e.g. selected row)
var grid = $("#grid"),
rowId = grid.getGridPara('selrow'),
num = grid.find("#"+rowId+" span.numData").attr("data-num");
(or you can directly use .data() for latest jquery 1.4.4)
In order to get the cell value when in-line editing you need to capture this event(or another similar event, check documentation):
beforeSaveCell: function (rowid, celname, value, iRow, iCol) { }
In the value parameter you have the 'value' of the cell that was currently edited.
To get the the rest of the values in the row use getRowData()
I lost a lot of time with this, hope this helps.
My workaround is to attach an object containing orignal values to each tr element in the grid. I've used afterAddRecord callback to get my hands on the values before jqGrid throws them away and jQuery's "data" method to store them in the work.
Example:
afterInsertRow: function( rowid, rowdata, rowelem ) {
var tr = $("#"+rowid);
$(tr).data("jqgrid.record_data", rowelem);
},
“rowelem” is the array of cell values from our JSON data feed or [jsonReader] (http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#jsonreader_as_function)
Then at any point I can fetch those attributes using:
$(tr).data(“jqgrid.record_data”).

I think that Aidan's answer is by far the best.
$('#yourgrid').jqGrid("editCell", 0, 0, false);
This commits any current edits, giving you access to the real value. I prefer it because:
You don't have to hard-code any cell references in.
It is particularly well suited to using getRowData() to get the entire grid, as it doesn't care which cell you've just been editing.
You're not trying to parse some markup generated by jqGrid which may change in future.
If the user is saving, then ending the edit session is likely the behaviour they would want anyway.
Before i was getting :
html tag of the textbox something like
but Here is the solution to get the value from that particular column, working and tested
function getValue(rowId, cellId) {
var val = $("[rowId='"+rowId+"'][name='"+cellId+"']").val();
return val;
}
var values = getValue(rowId, 'cellid');
I obtain edit value using javascript:
document.getElementById('idCell').value
I hope this info useful for someone.
I needed the original value before the formatter, so this is what I did:
{
name: 'Slot', title: false, formatter: function (cellValue, options, rowObject) {
rowObject['SlotID'] = cellValue; // <--- This saves the original ID
if (somelogic) {
return someString;
} else {
return someOtherString;
}
}
},
{ name: 'SlotID', hidden: true }
Now SlotID contains the original ID. Also, you don't need to have SlotID property on your original model.
try subscribing to afterEditCell event it will receive (rowid, cellname, value, iRow, iCol) where value is your a new value of your cell
You can use getCol to get the column values as an array then index into it by the row you are interested in.
var col = $('#grid').jqGrid('getCol', 'Sales', false);
var val = col[row];
