How to draw a border around each element in ItemsControl?

Question

I'm using an ItemsControl and a ItemTemplateSelector to draw display the UI of my items. But now, all my elements need to be inside in a Grid (and one of its columns the element should be there).

At the beginning I supposed was right to have a ContentControl nested in an ItemsControl, and this ContentControl should have the ItemTemplateSelector, but I'm not sure if this is the best way to do it.

Answer 1

Stuff like that should be in the Template of the item container, for ItemsControls that is a bit problematic as the containers are ContentPresenters which have no Template. You could subclass ItemsControl to use a ContentControl, then use the ItemsControl.ItemContainerStyle to edit the Template of those containers.
