Grouping not working

[arijit]

I am trying to use grouping to one of the RadGrid where all the columns are autogenerated
 
i applied the code.
 

ShowGroupPanel="True" (RadGrid attribute)

and

<ClientSettings AllowDragToGroup="True" >
 
</ClientSettings>
 
But when ever I am dragging one column to the group panel ,
 getting this
 
Error: Sys.WebForms.PageRequestManagerServerErrorException: Unable to cast object of type 'Telerik.Web.UI.GridGroupSplitterColumn' to type 'Telerik.Web.UI.GridBoundColumn'.

 
Please Help
