I need to customize the groupings in a grid.
In my case, I group by a column 'GridDropDownColumn' which has as public properties 'DataField = "ID"' and 'ListTextField = "description"', so in group shows a number instead of the description provided in the 'DropDown'.

If I use your suggestion is an error: "Can not find the Description column."
Let me explain, my Column is:

<telerik:GridDropDownColumn DataField="ID" DataSourceID="LinqDataSourceConto"
 
 HeaderText="Cont" ListTextField="Description" ListValueField="ID" UniqueName="ID"
 
 ColumnEditorID="GridDropDownColumnEditor1" AllowFiltering="false">
 
 </telerik:GridDropDownColumn>

with his datasource:

<asp:LinqDataSource ID="LinqDataSourceConto" runat="server" ContextTypeName="LinqDataSourceDataContext"
EnableDelete="True" EnableInsert="True" EnableUpdate="True" TableName="CONT">
</asp:LinqDataSource>

 

The grid uses the identifier value ID, but I would rather see a description that is inside of another "datasource" described in the 'GridDropDownColumn', obviously I can not use Vista because in this case I could not use the grid to online editing.
