I have 2 queries on binding jgGrid in MVC application..
1. I am unable to bind jsonData which is coming from controller on Success callback method
2. On button click i am loading jqgrid from server data, but when i click 2nd time it is not firing my server code(which is in controller), only first time it is executing the server code.
below is my javascript code
function buildGrid() {
// setup custom parameter names to pass to server prmNames: { search: "isSearch", nd: null, rows: "numRows", page: "page", sort: "sortField", order: "sortOrder" }, // add by default to avoid webmethod parameter conflicts postData: { searchString: '', searchField: '', searchOper: '' }, // setup ajax call to webmethod datatype: function(postdata) { mtype: "GET", $.ajax({ url: 'PageName.aspx/getGridData', type: "POST", contentType: "application/json; charset=utf-8", data: JSON.stringify(postdata), dataType: "json", success: function(data, st) { if (st == "success") { var grid = jQuery("#list")[0]; grid.addJSONData(JSON.parse(data.d)); } }, error: function() { alert("Error with AJAX callback"); } }); }, // this is what jqGrid is looking for in json callback jsonReader: { root: "rows", page: "page", total: "totalpages", records: "totalrecords", cell: "cell", id: "id", //index of the column with the PK in it userdata: "userdata", repeatitems: true }, colNames: ['Id', 'First Name', 'Last Name'], colModel: [ { name: 'id', index: 'id', width: 55, search: false }, { name: 'fname', index: 'fname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} }, { name: 'lname', index: 'lname', width: 200, searchoptions: { sopt: ['eq', 'ne', 'cn']} } ], rowNum: 10, rowList: [10, 20, 30], pager: jQuery("#pager"), sortname: "fname", sortorder: "asc", viewrecords: true, caption: "Grid Title Here" }).jqGrid('navGrid', '#pager', { edit: false, add: false, del: false }, {}, // default settings for edit {}, // add {}, // delete { closeOnEscape: true, closeAfterSearch: true}, //search {} ) });

{ });
}
above method is called in document.ready function
$(documen).ready(function() {
("#buttonclick").click(function() {
buildGrid();
});
});
Can you please what was wrong with my code.. because i need to search on button click by passing the paramerter's to service method using postData {},but how to send this postData to url and bind the result to JqGrid.
thanks

Usage of datatype as is not recommend way. Instead of that one can use datatype: "json". It informs that jqGrid should make for you the Ajax request using $.ajax method. One can use additional options of jqGrid to specify the options of the underlying $.ajax request.
The next problem you have in the code
$(documen).ready(function() {
$("#buttonclick").click(function() {
buildGrid();
});
});
The function buildGrid will be called every time if the user click on #buttonclick button. The problem is that you have initially the empty table
<table id="jQGrid"></table>
on your page, but after creating the grid (after the call $("#jQGrid").jqGrid({...});), the empty table will be converted in relatively complex structure of dives and tables (see the picture). The second call on non-empty table will be just ignored by jqGrid. It's the reason why the 2nd click on the button #buttonclick do nothing.
You can solve the problem in two ways. The first would be including $("#buttonclick").jqGrid("GridUnload"); before creating the grid. It would be destroy the grid and recreate the initial empty table. The second way os a little better. You can not destroy the grid at the second time, but to call $("#buttonclick").trigger("reloadGrid"); instead. It will force making new Ajax request to the server.
Minimal changing of your original code will follow us to about the following:
$(documen).ready(function() {
var $grid = $("#jQGrid");
$grid.jqGrid({
//setup custom parameter names to pass to server
prmNames: {
search: "isSearch",
nd: null,
rows: "numRows",
sort: "sortField",
order: "sortOrder"
},
// add by default to avoid webmethod parameter conflicts
postData: {
ddlDSVIN: function () {
return $('#ddlDevice').val();
},
search: function () {
return $("#searchId").val();
},
OEMType: function () {
return $('#ddlOEM')
.find("option")
.filter(":selected")
.text();
},
frmDate: function () {
return fromDate.toDateString();
},
toDate: function () {
return toDate.toDateString();
}
},
mtype: "POST",

datatype: "json",
ajaxGridOptions: { contentType: "application/json; charset=utf-8" },
loadComplete: function () {
$('#showgrid').show();
$('#jQGrid').show();

$("#hideandshow").show();
$("#lblTotal").html($(this).getGridParam("records") + " Results");
$("#hideandshow2").hide();
},
jsonReader: {

return typeof obj.d === "string" ?
$.parseJSON(obj.d) :
obj.d;
},

},

{ closeOnEscape: true, closeAfterSearch: true} //search
);
$("#buttonclick").click(function() {
$grid.trigger("reloadGrid");
});
});
I have below setup jqgrid (v 4.6.0).
$(function () {
var JQGridDefaults = {
caption: '',
rowList: [10, 50, 100],
datatype: 'json',
height: '100%',
viewrecords: true,
mtype: 'GET',
colNames: ['Item Control No', 'Item Short Description', 'ID'],
colModel: [

sopt: ['eq', 'ne', 'bw', 'bn', 'ew', 'en', 'cn', 'nc'],
},
searchrules: {required: true}
},
{
name: 'ItemShortDesc', index: 'ItemShortDesc', search: true, width: 300, cellattr: makeCellContentWrap, searchoptions: {
sopt: ['eq', 'ne', 'bw', 'bn', 'ew', 'en', 'cn', 'nc'],
},
searchrules: {required: true }
}
//Hidden Fields - Start
{ name: 'ItemID', hidden: true, key: true }
//HiddenFields End
],
pager: '#GridPager',
rowNum: 10,
sortname: 'ItemCode',
sortorder: 'asc',
url: '/Items/List',
jsonReader: {
root: "rows",
page: "page",
total: "total",
records: "records",
repeatitems: false,
userdata: "userdata",
subgrid: {
root: "rows",
repeatitems: false
}
},
//Sub Grid - Start
subGrid: true,
subGridBeforeExpand: function (pID, rowID) {
console.log("Before Expand");
var gridData = $(this).jqGrid('getRowData',rowID);
if (gridData.ItemCode == "") {
return false;
}
},
subGridUrl: '/Items/Details',
subGridModel: {
name: ['Revision', 'ItemCode'],
width: [50, 100],
align: ['center', 'center'],
mapping: ['Revision', 'ItemCode']
},
afterInsertRow: function (rowid, aData, rowelem) {
// Remove the subgrid plus button except for rows that have exceptions
if (aData.ItemCode == "") {
$('#' + rowid).children("td.sgcollapsed").unbind();
$('#' + rowid).children("td.sgcollapsed").html("");
}
}
//Sub Grid - END
};
var JQGridSearchDefaults = {
multipleSearch: true,
recreateFilter: true,
showQuery: true,
closeAfterSearch: true,
closeAfterReset: true,
searchOnEnter: true,
closeOnEscape:true,
width: 600
};
$('#Grid').jqGrid(JQGridDefaults).navGrid('#GridPager', { view: false, del: false, add: false, edit: false, refresh: true },
{},
{},
{},
JQGridSearchDefaults);
$('#Grid').jqGrid('setGridWidth', $('#Grid').parents('.main-content').width() - 2);
$(window).resize(function () {
clearTimeout(this.id);
this.id = setTimeout(function () {
$('#Grid').jqGrid('setGridWidth', $('#Grid').parents('.main-content').width() - 2);
}, 300);
});
});
The sub grid icon appears correctly but when I click on the Expand icon an empty row appears (no headers and no ajax call is sent)
does anyone have an idea on why the ajax call is not happening?
Note: I also tried to use 'subgridtype' parameter and define to make the service call that too did not make the Ajax call.
subgridtype: function (rowidparam) {
$.ajax({
url: '/Items/Details',
cache: false,
type: 'Get',
dataType: "json",
data: { id: rowidparam.ItemID }
}).done(function (data) {
$('#Grid')[0].subGridJson(data, rowidparam.id);
});
},
subgridtype must be string, for you try json
subgridtype: 'json'
I have the following code in page which binds the data to j query grid.
Now i want to add one more column for check-boxes to the existing grid and when i select some check boxes and press some button .. i need to get the selected row values .
I have seen some tutorials for this they mentioned about some formatter .... but they are not clear
Please help me to achieve this.
Thanks in advance.
Code:
$(document).ready(function () {
$("#btn_GenerateEmpList").click(function () {
var firstClick = true;
if (!firstClick) {
$("#EmpTable").trigger("reloadGrid");
}
firstClick = false;
var empId= $("#txt_emp").val();
$.ajax({
type: "POST",
url: "PLBased.aspx/GetEmpNames",
data: JSON.stringify({ empId: empId}),
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (result) {
result = result.d;
jQuery("#EmpTable").jqGrid({
datatype: "local",
colNames: ['Emp Name'],
colModel: [
{ name: "EmpName", Index: "EmpName", width: 80 }
],
data: JSON.parse(result),
rowNum: 10,
rowList: [5, 10, 20],
pager: '#pager',
loadonce: false,
viewrecords: true,
sortorder: 'asc',
gridview: true,
autowidth: true,
sortname: 'EMPID',
height: 'auto',
altrows: true,
});
},
error: function (result) {
alert("There was some error ");
}
});
});
});
You can use customformatter to show checkbox in the column. For this, you can write the code as below in your jqGrid Code.
colNames: ['Id','Emp Name','Emp Checkbox'],
colModel: [
{ name: 'Id', index: 'Id', hidden: true },
{ name: 'EmpName', Index: 'EmpName', width: 80 },
{ name: 'Empchk', Index: 'Empchk', width: 50, align: 'center', editable: true, edittype: "checkbox", editoptions: { value: "true:false" },
formatter: generateEmpCheckBox, formatoptions: { disabled: false } }
],
formatter function code as below,
function generateEmpCheckBox(cellvalue, options, rowObject) {
var checkedStr = "";
if (cellvalue == true) {
checkedStr = " checked=checked ";
}
return '<input type="checkbox" onchange="UpdateEmpcheckbox(' + rowObject.Id + ',this)" value="' + cellvalue + '" ' + checkedStr + '/>';
}
function UpdateEmpcheckbox(selectedId, chkBox) {
if ($(chkBox).prop("checked")) {
//you can write an ajax here, to update the server
//when the checkbox is checked
}
else if (!($(chkBox).prop("checked"))) {
//you can write an ajax here to update the server
//when the checkbox is unchecked
}
return false;
}
Set the option multiselect:true which will add column of checkboxes. Then add
$('#EmpTable').jqGrid('getGridParam', 'selarrrow')
will return an array of selected id's.
When I use my jqgrid (v.4.6) on page evrything is ok.
When I load jqgrid via ajax to jquery dialog searchoptions dropdown list doesn't work for me.
In jqgrid search box searchoptions dropdown list doesn't work for me either.
$(document).ready(function(){
jQuery("#list_bs").jqGrid({
url:'some.php',
datatype: "json",
height: 450,
width: 1050,
colNames:['FirstName','Name','Date'],
colModel:[
{name:'FirstName',index:'FirstName', width:200, sorttype:'string', searchoptions:{sopt:['bw','bn','cn','ne','ew','en']}},
{name:'Name',index:'Name', width:200, sorttype:'string', searchoptions:{sopt:['bw','bn','cn','ne','ew','en']}},
{name:'Date',index:'Date', width:100, sorttype:'string', searchoptions:{sopt:['bw','bn','cn','ne','ew','en']}},
],
rowNum:50,
rowList : [20,30,50],
loadonce:false,
multiselect : false,
mtype: "GET",
shrinkToFit: false,
rownumbers: true,
gridview: true,
pager: '#pager',
sortname: 'Name',
viewrecords: true,
sortorder: "ASC",
toolbar: [true,"top"],
});
$("#list_bs").jqGrid('navGrid', '#pager_bs',
{
edit:false,
add:false ,
del:false,
},
{},
{},
{},
{
multipleSearch: true,
showQuery: true
}
......
)
});
jQuery("#list_bs").jqGrid('filterToolbar',{ searchOperators: true,stringResult:true, searchOnEnter: false, autosearch: true ,enableClear: false});
try like below this work for me.You have give data in the dropdown in its column model
{
name: 'Name', Name: 'Title', align: 'center', editable: true, editoptions: { readonly: 'readonly' },
stype: 'select',
searchoptions: {
sopt: ['eq','cn'],
dataUrl: //get data from server
buildSelect: function (data) {
var response, s = '<select>', i;
response = jQuery.parseJSON(data);
s += '<option value="0">--Select Book Title--</option>';
if (response && response.length) {
$.each(response, function (i) {
s += '<option value="' + this.Name+ '">' + this.Name+ '</option>';
});
}
return s + '</select>';
}
}
}
I don't need dropdown in toolbar input
My search operator dropdown list doesn't open.
The problem is only when my own jqgrid is loaded by ajax in to jquery dialog.
$( "#my_dialog" ).dialog({
width:'auto',
open: function(event, ui){
$.ajax(
{
url: "some.php",
type: "POST",
data: "is_dialog=true",
error: function(){
},
beforeSend: function(){
$("#loader").show();
},
complete: function(){
$("#loader").hide();
},
success: function( strData ){
$("#dialog_content").html(strData );
}
}
);
},
});
...........
<div id="my_dialog" >
<div id="dialog_content"></div>
</div>
where in one cell edittype is select with key value pair like below.
colModel: [
{name: 'Code', index: 'Code', width: '16%', editable: true, sortable: true },
{ name: 'ABC', index: 'ABC', width: '16%', editable: true, edittype: "select", editoptions: { value: "FE:FedEx;TN:TNT"} },
{ name: 'Emailid', index: 'Emailid', width: '16%', editable: true, sortable: true },
],
Now while adding new row if i selected the FedEx for ABC column it will send the FE to EditURL Link not FedEX so i want to send the FEDEX using extraParam to EditURL.
So please anyone let me know how to implement it.
For this my code is below

Update code of Oleg
var grid = jQuery("#list5"),
