Hello!

I've got a question on sorting NavigationProperties.

Lets say I have a BusinessObject (Panel) which includes a NavigationProperty with the Name Tasks.
I'm binding this NavigationProperty to a SilverlightControl and I want to Display the Tasks sorted by one Property.

How can I do this?
PropertyInterceptors?

Thank You for your answer.

Rainer

If you need to operate on the collection in the UI, you should put the entities into an ObservableCollection and then you can implement sort on the list.  This link talks about how to do this with an extension method or by subclassing.  Check out the June 3, 2010 post at the bottom:
