Implementing a Master-Detail style UI with the CollectionViewModel I described in my previous post is pretty easy. With a selector control bound to a CollectionViewModel as shown in my previous post, you just need to add a content control to the View and bind its Content property to the current item and define how you want it to be rendered by defining a data template.
For the sample in my previous post the view’s XAML contains this:
Note: In WPF, you strictly only need to bind the content control’s Content property to the Catalog – WPF automatically binds to the Catalog’s current item for you. Not sure why they did it this way. I think an explicit binding to the CurrentItem property is easier to understand, and I don’t mind typing the extra characters. Sometimes a little more is definitely more
