A customer recently opened a support case asking for a sample of a grid-like drop-down (i.e., multiple columns with a single header) in a XamComboEditor. The reply below contains the sample; I hope this sample will be useful to others...

<TextBlock Text="{Binding Path=Mansione}" Margin="4, 0, 0, 0" Width="150"/>
</StackPanel>
</DataTemplate>
thank you very much
There are a couple of comments in the XAML at the places where I had to change the default templates.
I changed the default template of both the XamComboEditor control, and the ComboEditorItemControl, then used the ItemTemplate in thecontrol to make this work.
· In the XamComboEditor I added another Grid panel to the template to add the headers in the popup.
· In the ComboEditorItemControl I changed the container that holds the checkbox and the items contentpresenter so that the content would stretch to the width of the popup.
· In the actual XamComboEditor control, I just use the ItemTemplate to define the content of each item in the popup.
