Team,

In my application am generating Datatable at runtime. Then directly binding this Datatable to Radgrid.
My need is I want to apply sorting through code behind on the Dynamically generated columns.
Pls. help on this.

Markup is as below:

<

 

telerik:RadGrid ID="MainGrid2" runat="server" ShowHeader = "true"

 

 

GridLines="Both" OnPreRender="AnswerGenMainGrid1_PreRender" Skin="none"

 

 

OnItemDataBound="MainGrid2_ItemDataBound" EnableEmbeddedSkins = "false" OnItemCreated = "MainGrid2_ItemCreated" >

 

 

 

 

 

</telerik:RadGrid>

Thanks in Advance
r

Hello Rajesh,

 I assume that you are binding the grid in PageLoad event, which is Simple data binding technique. If you are using any advanced feature in grid, then a better approach is using "AdvancedData binding" using NeedDataSource event. Set the DataSource in NeedDataSource event and set the AllowSorting property of RadGrid to True. RadGrid fires the NeedDataSource event each time it needs to be bound to a data source. For more information about this can be available here:

Advanced Data-binding (using NeedDataSource event)

Thanks,
Princy.
