Grid client databinding (data loading indicator?)

[loi]

I'm just wondering if there is built-in option in the Grid to show some kind of indicator while the grid is loading data on the client side..
Most of our MVC grids are loading data via ajax databinding.. and sometimes it can take a while to before the data is loaded.. We need some sort of indicator to tell users that a grid is loading data.

So far, our work-around was to use this jquery plugin below in the OnDataBinding and OnDataBound grid client events
http://code.google.com/p/jquery-loadmask/

@(Html.Telerik().Grid(Model)

    .Name("TestingGrid")

    .DataBinding(dataBinding => dataBinding.Ajax().Select("_GetSomeData", "Test", new { categoryID = ViewBag.CategoryID}).OperationMode(GridOperationMode.Client))   

    .Sortable(sorting => sorting.SortMode(GridSortMode.SingleColumn))

    .Footer(false)

    .Columns(columns =>

    {

        columns.Bound(o => o.Selected)

            .Title(" ")

            .Width(150)

            .Sortable(false);       

        columns.Bound(o => o.Text)

            .Title("Text");

        columns.Bound(o => o.Value)

            .Title("Name");

    })

    .ClientEvents(events => events

            .OnDataBinding("onGridDataBinding")

            .OnDataBound("onGridDataBound"))

)

 
<script type="text/javascript">

 

    function onGridDataBinding(e)

    {

        $(this).mask('Loading');

    }

    function onGridDataBound(e)

    {

         $(this).unmask();

    }

 

</script>

Is there a built-in support for this that I missed?

Hello Misterii0,

The Grid natively provides a loading indicator inside its pager row. You can see it in action here:

http://demos.telerik.com/aspnet-mvc/grid/externalservicetwitter

If this is not visible enough for your users, you can implement a custom loading panel, and show and position it manually. Show it in the Grid's OnDataBinding event and hide it in the OnDataBound event.
