Hello, have good time
I have a page where it's a grid.

In this grid one of the columns is hidden where the user ID is and in the other column it fills the user name with another List in the event ItemDataBound
But when grouping it shows the user ID while I need the name to show it.


01.<telerik:RadGrid ID="RadGrid1" runat="server" ShowFooter="true" AllowFilteringByColumn="true" GroupingEnabled="true" ShowGroupPanel="True"
02.                ClientSettings-AllowDragToGroup="true" AllowSorting="true" AllowPaging="true" PageSize="5" Skin="WebBlue" AllowMultiRowSelection="false" CellSpacing="-1" GridLines="Both"
