jqGrid sorting on client side

Question

I have a tree-grid with autoloading rows. The goal is to sort the grid by tree column, right on client side.

But each time I click on sort column he

Answer 1

I'm using client-side sorting on jqGrid and retrieving a new set of json data when a select list changes. You need to set rowTotal to an amount higher or equal to the number of rows returned, and then set the data type to 'json' just before reloading the grid.

// Select list value changed
$('#alertType').change(function () {
        var val = $('#alertType').val();
        var newurl = '/Data/GetGridData/' + val;
        $("#list").jqGrid().setGridParam({ url: newurl, datatype: 'json' }).trigger("reloadGrid");        
});

// jqGrid setup
$(function () {
        $("#list").jqGrid({
            url: '/Data/GetGridData/-1',
            datatype: 'json',
            rowTotal: 2000,
            autowidth: true,
            height:'500px',
            mtype: 'GET',
            loadonce: true,
            sortable:true,
            ...
            viewrecords: true,
            caption: 'Overview',
            jsonReader : { 
                root: "rows", 
                total: "total", 
                repeatitems: false, 
                id: "0"
            },
            loadtext: "Loading data...",
        });
    });
