    I'm using this example to create a dynamic gridview:
    http://blogs.telerik.com/vladimirenchev/posts/11-09-28/dynamic-binding-for-your-silverlight-applications.aspx

    In my application the first 3 columns always have the same column header.
    Is it possible to group these 3 columns directly after loading and hide the grouped header?
    I've tried to use
    <telerik:RadGridView.Columns>
     <telerik:GridViewDataColumn DataMemberBinding="{Binding Location}" Header="Location" IsFilterable="True" 
        IsGroupable="True" IsReadOnly="True" IsReorderable="False" IsResizable="True" IsSortable="False" UniqueName="Location" 
       ShowColumnWhenGrouped="False" />
    </telerik:RadGridView.Columns>
      
    <telerik:RadGridView.GroupDescriptors>
           <telerik:GroupDescriptor Member="Location"
                                  SortDirection="Ascending" />
     </telerik:RadGridView.GroupDescriptors>
    and
    private void Grid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
    {
        if (e.Column.UniqueName == "Location")
        {
            e.Cancel = true;
        }
    }

    But this is not working in combination with 
    AutoGenerateColumns="True"

    hi,
     i am using telerik gridview to display data.. it works really great.. 
    but i when i am using grouping that makes some problem to me...

    i have created approximate 8 groups(a->b->c so on.. ) in gridview. now suppose in my first group there are only one sub group. But it show me all the 8 sub group in it.. 
    i am attaching the screen shot of the grid.. 

    so if it is possible to reduce some unnecessary sub groups.. 

    with regards
    Rikin
