I need to hide the delete button if there are less than 2 records in the grid. This is the js code. For some reason, the flag showDelCurrencyButton is not working out here and is always false.
Any other way to do it?
showDelCurrencyButton = false;
grid.jqGrid({
datatype: 'local',
jsonReader: jqgrid.jsonReader('CurrCd'),
mtype: 'POST',
pager: '#currencyPager',
colNames: ['Abbrev.', 'Name', 'Symbol'],
colModel: [
{
name: 'CurrCd', index: 'CurrCd', width: 200, sortable: false,
editable: true,
edittype: 'select', stype: 'select',
editrules: { required: true },
editoptions: {
dataUrl: getServerPath() + 'Ajax/GetCurrencies',
buildSelect: function (data) {
var currSelector = $("<select id='selCurr' />");
$(currSelector).append($("<option/>").val('').text('---Select Currency---'));
var currs = JSON.parse(data);
$.each(currs, function () {
var text = this.CurName;
var value = this.CurCode;
$(currSelector).append($("<option />").val(value).text(text));
});
return currSelector;
}
}
},
{ name: 'CurrName', index: 'CurrName', width: 200, sortable: false },

],

loadComplete: function (data) {
if (data.length > 1) {
showDelCurrencyButton = true;
}
var rowIds = $('#currencyGrid').jqGrid('getDataIDs');
$("#currencyGrid").jqGrid('setSelection', rowIds[0]);
},
rowNum: 1000
});
grid.jqGrid('navGrid', '#currencyPager', {
edit: false,
del: (showDelCurrencyButton == true),
deltitle: 'Delete record',
search: false,

}
});
Your current code uses datatype: 'local' without specifying data parameter with input data. It seems strange. In any way you can hide the Delete button dynamically identifying it by id. It's "del_" + grid[0].id in your case. Thus you can use $("#del_" + grid[0].id).hide(); to hide it. By the way one can use this instead of grid[0] inside of loadComplete.
I'd recommend you to read the old answer for more details and to read the answer, which shows how to disable/enable navigator buttons (like Delete button) instead of hiding.
My jqgrid is working perfectly but now i am implementing the subgrid. It shows the + sign and when i click on it the blank row displayed with loading.... this is the client side code
$(document).ready(function () {
$("#Grid").jqGrid({
url: '/Home/GetDetails',
datatype: 'json',
myType: 'GET',
colNames: ['id','Name', 'Designation', 'Address', 'Salary'],
colModel: [
{ key: false, name: 'Id', index: 'Id', },
{ key: false, name: 'Name', index: 'Name', editable: true },
{ key: false, name: 'Designation', index: 'Designation', editable: true },
{ key: false, name: 'Address', index: 'Address', editable: true },
{ key: false, name: 'Salary', index: 'Salary', editable: true }
],
jsonReader: {
root: 'rows',
page: 'page',
total: 'total',
records: 'records',
id: '0',
repeatitems: true
},
pager: $('#pager'),
rowNum: 10,
rowList: [10, 20, 30],
width: 600,
viewrecords: true,
multiselect: true,
sortname: 'Id',
sortorder: "desc",
caption: 'Employee Records',
loadonce: true,
gridview: true,
autoencode: true,
subGrid: true,
subGridUrl: '/Home/Subgrid',
subGridModel: [{
name: ['No', 'Item','Quantity'],
width: [55, 55,55]
}
],
}).navGrid('#pager', { edit: true, add: true, del: true },
{
zIndex: 100,
url: '/Home/Edit',
closeOnEscape: true,
closeAfterEdit: true,
recreateForm: true,
afterComplete: function (response) {
if (response.responseText)
{
alert(response.responseText);
}
}
},
{
zIndex: 10,
url: '/Home/Add',
closeOnEscape: true,
closeAfterEdit: true,
recreateForm: true,
afterComplete: function (response) {
if (response.responseText) {
alert(response.responseText);
}
}
},
{
zIndex: 100,
url: '/Home/Delete',
closeOnEscape: true,
closeAfterEdit: true,
recreateForm: true,
afterComplete: function (response) {
if (response.responseText) {
alert(response.responseText);
}
}
}
);
});
Subgrid url action method is as below:
public JsonResult Subgrid(String id)
{
Database1Entities db = new Database1Entities();
Product p= new Product {No=1,Item="Juice",Quantity=23};
var jsondata = new { rows=2,
cell = new string[] { p.No.ToString(),
p.Item,p.Quantity.ToString()}.ToArray()
};
return Json(jsondata, JsonRequestBehavior.AllowGet);
}
I am doing this first time. What is the mistake?Thanks in advance
I don't recommend you to use subGridModel. Instead of that it's much more flexible to use Subgrid as Grid. If the user clicks "+" icon (expand subgrid) then jqGrid just inserts empty row under selected with simple structure described in the answer for example. The id of the <div> where some custom "subgrid" information need be displayed will be the first parameter of subGridRowExpanded callback which you need to implement. The second parameter is the rowid of the expending row. By implementing the corresponding callback you can create any custom "subgrid". See the old answer for very simple demo.
So what you need to do is just write the code which creates grid which will be placed in subgrid row. It's only strictly recommended to use idPrefix parameter which used any values which depends from subgriddivid or parent rowid. Additionally you can consider to use autowidth: true option for subgrid, which will make the width of subgrid be exact correspond to the width of the main grid. Of cause to have rowid of the parent row send as id parameter to '/Home/Subgrid' you need use postData: { id: rowid }. See the code from the answer for example which I referenced previously.
Problem: unable to get updatable value of textbox in jqgrid.
It just retrieve old value.
example - default value of textbox field inside jqgrid is - "0"
now, if i update its value to "1" and inspect the field then its value does not get updated into HTML and not able to retrieve with jqgrid object through below syntax.
var rowData = $('#gerList').jqGrid('getRowData', rowId);
Below is my jqgrid stuff:
$('#gerList').jqGrid({
ajaxGridOptions: {
error: function () {
$('#gerList')[0].grid.hDiv.loading = false;
alert('An error has occurred.');
}
},
url: '#Url.Action("GetEnrolls", "Attendance")/' + 0,
gridview: true,
autoencode: true,
postData: { adID: rowID },
datatype: 'json',
jsonReader: { root: 'List', page: 'Page', total: 'TotalPages', records: 'TotalCount', repeatitems: false, id: 'syStudentID' },
mtype: 'GET',
colNames: ['GrdID', 'name', 'Minutes', 'comment'],
colModel: [
{ name: 'syID', index: 'syID', hidden: true },
{ name: 'FullName', index: 'FullName', width: 150 },
{
name: 'Min', index: 'Min', width: 75, align: 'left', formatter: function (cellValue, option) {
return '<input type="text" style="width: 40px" name="txtMin" id="txt_' + option.rowId + '" value="' + cellValue + '" />';
}
},
{ name: 'MSG', index: 'MSG', width: 150 }
],
pager: $('#gerListPager'),
sortname: 'syStudentID',
rowNum: 40,
rowList: [40, 80, 120],
width: '525',
height: '100%',
viewrecords: true,
beforeSelectRow: function (rowid, e) {
console.log("final");
var $txt = $(e.target).closest('tr').find('input[type="text"]');
alert($txt);
$txt.attr('value', rowid);
return true; // allow row selection*/
return true;
},
sortorder: 'desc'
}).navGrid('#gerListPager', { edit: false, add: false, del: false, search: false, refresh: false });
Please suggest me what is wrong to use this textbox in jqgrid.
In grid UI, all fields are non editable except textbox field appear to allow edit always.
Thanks
Try to use this:
jQuery("#gerList").saveRow("rowid", false, 'clientArray');
Am using jqgrid, loading data once, sorting and filtering locally and doing a refresh after each update/insert/delete. It works fine, besides that if I am using a filter (on top of grid), the filter remains the same after refresh, but the filter is not re-applied on the newly loaded data.
I have tried to call mygrid[0].triggerToolbar() after reloading grid with trigger('reloadGrid'), but there is no effect.
Thanks for any help or pointers :-)

I have poured through every question asked on this website related to populating the jqGrid summary footer WITHOUT the userdata being a server request. And the jqGrid wiki resource and just cannot find an answer. Is this possible to do?
I use the jqGrid in many typical ways as part of my admin portal but have one particular use where I want the look & feel of the jqGrid to start out as an empty UI container of sorts for some user interaction adding rows through a form which doesn't post on Submit (thanks to Oleg's great script below) but simply adds the row and updates the summary footer with the values from the newly added row. I have 'summarytype:"sum"' in the colModel, "grouping:true", footerrow: true, userDataOnFooter: true, altRows: true, in the grid options but apart from the initial values supplied by the userdata in the local data string, the summary footer values never change. It seems like no one wants to touch this subject. Is it because the primary nature of the jqGrid is it's database driven functionality? I use about 15 instances of the jqGrid in it's database driven stance (many of which are in a production service now) but need to use it for consistency sake (all my UI's are inside jqTabs) initially as a client side UI with no server request (everything will be saved later to db) but I am pulling my hair out trying to manipulate the summary footer programmatically on and by the client only. Can anyone suggest how to cause values to the summary footer to update when a new row is added the values of which would be summed up with any existing rows and which does not involve any posting to server, just updates inside the grid?
The code supplied is kind of long and based primarily on user Oleg's solution for adding a row from a modal form without posting to the server. I've changed the local array data to JSON string simply to better understand the notation as I'm used to xml. The jsonstring initializes the grid with one default row for the user to edit. I've left out the jsonReader because the grid would not render with it.
In a nutshell then what I want to do is to have the summary footer update when a new row is added to the grid (no posting to server occurring at this point) or edited or deleted. When a certain set of values is achieved the user is prompted by a displayed button to save row data to db.

In case of "local" datatype one can use footerData method to set (or get) the data in the footer. Additionally the method getCol can be used co calculate the sum of elements in the column.
Look at the answer for more information. I hope it will solve your problem.
