Hi,

Sorting is not happening on the click of column headers. The "Loading..." shows up briefly over the data, but the columns are not getting sorted. Also, "OnSortCol" event gets triggered and I could see the alert popping up. But, the sorting is not happening. Any help on this is appreciated.

Please find below the code:

C#

jQuery("#jqTable").jqGrid({
            dataType: 'local',
            altRows: true,
            colNames: ["ID", "First name", "Last name", "Role", "Group", "Location", "Status", "<div class='selectgriddiv'>Select all</div>" + "<div class='selectgriddiv'><input type='checkbox' id='chkAll' name = 'chkSelectAll' onclick='checkBox(event)' /></div>", "Role Id", "Is Primary"],
            colModel: [
                {
                    name: "Id", index: "Id", align: "center", sortable: false, formatter: function (cellvalue, options, rowObject) {
                        if (_RoleId > rowObject.RoleId && rowObject.IsPrimary == false)
                            return "<img src='../images/ProcessImages.aspx.jpg' alt='my image' />" + "<br/>" + "<a id='linkToProfile' href='#' onclick='RedirectUsers(" + rowObject.Id + "," + rowObject.RoleId + "," + '"' + rowObject.RoleName + '"' + ")' >" + rowObject.Id + "</a>";
                        else if (_RoleId == rowObject.RoleId || _RoleId < rowObject.RoleId) {
                            return "<img src='../images/ProcessImages.aspx.jpg' alt='my image' />" + "<br/>" + rowObject.Id;
                        }
                        else if (_RoleId == rowObject.RoleId && _IsPrimary == false) {
                            return "<img src='../images/ProcessImages.aspx.jpg' alt='my image' />" + "<br/>" + rowObject.Id;
                        }
                    }
                },

Try adding sorttype to each of the sortable column. Also note taht client side sorting works for datatype as local for json a call is made to the specified url and server code needs to return the sorted data. The onSortCol gets called just before the call is made to to server or local sort routine. it basically allows you to stop the sorting.

Hello Ganesh,

For jQGrid if datatype other than "local" the sorting needs to get handled on the server side. For client side sorting the datatype must be "local" and each sortable column must have the sorttype property set (see this[^] link to know more about server side paging and client side sorting setup). The possible values for this property are

int/integer - for sorting integer
float/number/currency - for sorting decimal numbers
date - for sorting date
text - for text sorting
function - defines a custom function for sorting. To this function we pass the value to be sorted and it should return a value too.

The onSortCol function gets called immediately after the column header is clicked and just before sorting the data. If this event return 'stop' the sort processing is stopped and you can define your own custom sorting.
