Exception thrown when binding ItemsControl to a UserControls collection?

Wrote a custom control to solve this issue. Since all I wanted was to show usercontrols within a "parent" form, I ended up creating a custom panel control. Added a dependency property called ItemsSource to it.

The handler for this property adds the custom controls in its collection to the panel's Cldren collection.

If it is I obtain a reference to its parent panel control and remove the control from that parent panel's children collection. It seems to work just fine.

Thanks for the comments. A.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
