Hi,

When my application starts, I wanted it to start default with a grouping. I do this with defining a GroupDescriptor with deeper binding.

                    <RadGrid:RadGridView.GroupDescriptors>         
                            <Data:GroupDescriptor DisplayContent="Employee" Member="Employee.Name" SortDirection="Ascending" />         
                        </RadGrid:RadGridView.GroupDescriptors>         

When I run the program, the DisplayContent is shown in the grouping field and the grouping is done in the right way.

But when I want to open the xaml in blend then, I get an argument exception on the GroupDescriptor I just added.

-> MS.Internal.XcpImports.MethodEx(IntPtr ptr, String name, CValue[] cvData) at System.Windows.UIElement.UpdateLayout()

How can I solve this?

Have I used a property in the wrong way?

Thanks in advance
