Question

Love the new Implicit Data Templates, but I’ve just run into a problem with them.

My ComboBox is picking a DataTemplate which matches the ItemsSources type instead of following my DisplayMemberPath settings. Is there a way to tell the control to not look for DataTemplates?

     <ComboBox DisplayMemberPath="DTO.Name" SelectedValue="{Binding DefaultModifierGroup, Mode=TwoWay}" 
ItemsSource="{Binding MenuRepository.ModifierGroups, Source={StaticResource Locator}}"/>

I think you can’t use DisplayMemberPath anymore. You probably need to created new data template inside that combobox.
