Elegant way of exposing ItemContainerGenerator in custom control

What's the elegant way of exposing ItemContainerGenerator from custom control?

I have ItemsSource property on my custom control and I would like to access UIElement corresponding to the bound item outside of it.

I don't have access to the ItemsControl nor ItemsContainerGenerator outside of my control. Should I expose ItemsControl or ItemContainerGenerator as a property, or maybe add a method for retrieving the UIElement?

I need to show the popup near the selected item. Maybe the popup should be a part of the control then I wouldn't have to do this?

If you want to be able to access the entire child ItemsControl, create a public read-only property that returns it.

If you only want to expose the ItemContainerGenerator, create a read-only property that returns it, e.g.:

public ChildItemContainerGenerator => childControl.ItemContainerGenerator;

If it makes no sense to expose the entire ItemContainerGenerator, create a public method that uses the ItemContainerGenerator internally to perform whatever you want to.

Which option to choose all comes down to your requirements actually.
