Extending existing DependencyProperty (PropertyChangedCallback) RRS feed

  • Question

  • Hello,

    I've got an own class derived from ItemsControl. I want to catch ItemsSourceChanged event, which is existing in WPF. In Silverlight (I'm working with version 4.0) there is no such event. In due to there's an DependencyProperty called ItemsSourceProperty it would be very nice if I can assign a PropertyChangedCallback() to his metadata. As a matter of fact this property was declared as readonly in ItemsControl. Assigning to it is impossible.

    What can I do to solve this problem? Thanks in advance.
