Why does DisplayMemberPath does not work when put in Style for a WPF ComboBox?

Unless I add DisplayMemberPath on the combobox it does no开发者_如何学JAVAt work. I think it should take it from Style?

I have the comboBox initially disabled. I see it can work when I open another tab with same DataTemplate. Once it works on one instance, it imdly starts working on all. Is is anything to do with tabs?

 <Style x:Key="CollectionList" TargetType="ComboBox">
    <Setter Property="IsReadOnly" Value="True"/>
    <Setter Property="IsEditable" Value="True"/>
    <Setter Property="IsSynchronizedWithCurrentItem" Value="False"/>
    <Setter Property="DisplayMemberPath" Value="Name"/>
 </Style>


 <ComboBox ItemsSource="{Binding Items}" 
   Style="{StaticResource CollectionList}" 
   SelectedItem="{Binding Model.SelectedItem}" />

Change your Style="{StaticResource CollectionList}" to a DynamicResource

I am guessing it has something to do with the StaticResource getting loaded once, and the TabControl items getting loaded as needed
