I am trying to use the client-side API to filter a grid, but it is not doing anything at all. There are no Javascript errors either even though my breakpoint hits it in Firebug. Everything else works on the client-side even the sorting and filter headers, but my button click is not doing anything. Am I doing anything wrong here?

@(Html.Telerik().Grid(Model)
    .Name("RouteGrid")
    .Columns(columns =>
    {
        columns.Bound(r => r.RouteId).Title("Route #");
        columns.Bound(r => r.LongName).Title("Route:");
        columns.Bound(r => r.Description).Title("Description");
    })
    .ToolBar(toolBar => toolBar.Template(
        @<text>
            <input type="text" id="routes_search" />
            <input type="submit" id="routes_submit" value="" />
        </text>))
    .DataBinding(dataBinding => dataBinding.Ajax()
        .OperationMode(GridOperationMode.Client)
        .Select("GridAjax", "Routes"))
    .Sortable()
    .Filterable()
)
 
<script type="text/javascript">
    $(function() {
        $('#routes_submit').click(function(e) {
            var grid = $('#RouteGrid').data('tGrid');
            grid.filter("LongName~substringof~'" + $('#routes_search').val() + "'");
        });
    });
</script>

    public class RoutesController : Controller
    {
        public ActionResult Grid(string view)
        {
            return View(this.GetRoutes());
        }
 
        [GridAction]
        public ActionResult GridAjax()
        {
            return View(new GridModel(this.GetRoutes()));
        }
}

Hello Basem,

The problem is that the client filter() method is currently not supported in client operation mode. However, this can be workaround to a degree by manually parsing the filter expression and assigning it to the DataSource component of the grid. I have attached a modified version of a Code Library which covers similar to your scenario (using the ClientOperationMode).
I hope this helps.

Kind regards,
