Remarks

You might want to create a custom control that has the same functionality as an existing control and also exhibits the behavior of a Popup. You can make your control behave like a Popup by adding a Popup to your control and calling the CreateRootPopup method.

This method assigns child to the child property and binds the following properties to child.

You should implement these as dependency properties in your control so it can be used the same way as a Popup. For more information, see Custom Dependency Properties.

When you call CreateRootPopup, child cannot be a child of a UIElement. Also, PlacementTarget should be set on your control before you call this method.
