[Solved] SL4 beta GroupDescriptor Invalid Cast Exception

[Gary Paul]

I'm trying to programatically set a grouping:

private void btnCategorized_Click(object sender, RoutedEventArgs e)
{
    var gd = new GroupDescriptor();
    gd.Member="Category";
    gd.SortDirection=ListSortDirection.Ascending;
    grdProperties.GroupDescriptors.Add(gd);
}

This all steps through fine, but when I leave the message it immediately brings up the debugger which claims it can't attach to a crashing process.

If I bypass the Debugger the code goes to the Application Unhandled Event and states: Invalid Cast Exception.

I'm using VS2010 beta 2, in a SL 4 project using RadControls_for_Silverlight_2009_3_1208_TRIAL

Any suggestions?
