I'm using igGrid in the MVC3.

When the igGrid load first time the groupby works fine.

But after I call $("#igGrid").igGrid("dataBind"); groupby didn't work anymore after DataBind.

I have to setting some filters, and bind the data which base on the filters to the grid. (So I have to rebind data source)

Is there anything wrong with the code, or what else should I do?

Code as follow:

@( Html.Infragistics().Grid<MyModel>().ID("igGrid")
    .AutoGenerateColumns(true).PrimaryKey("ID")
    .Columns(column =>
    {
        column.For(x => x.ID).DataType("string").HeaderText("ID").Width("150px");
    })
    .Features(features =>
    {
        features.Resizing();
        features.Selection().MultipleSelection(true);
        features.Sorting().Type(OpType.Local);
        features.GroupBy().Type(OpType.Local);
        features.Paging().PageSize(100);
    })
    .DataSourceUrl(Url.Action("RequestMyData", "MyControl"))
    .Width("100%")
    .Height("100%")
    .DataBind()
    .Render()
    )

function refreshData() {
    $("#igGrid").igGrid("dataBind");
}

Control:

        [GridDataSourceAction]
        [ActionName("RequestMyData")]
        public ActionResult RequestMyData()
        {
            IQueryable<MyData> datas= DB.GetMyDats(filters);

            return View(datas);
        }
