Binding ElementName inside a DataTemplate

Question

I am trying to bind a property that is dependent on a control within the same DataTemplate.

To illustrate:

    <         


        

Answer 1

This is probably a namescope issue, the binding is not a framework element, any objects inside it will not share the outside namescope, nor is the binding in any tree, so relative source bindings should fail as well.

You can try using x:Reference instead, it uses a different mechanism:

{Binding SelectedItem, Source={x:Reference ComboList}}
