Description

A TargetInvocationException occurs when selecting a Header or Footer after changing the ItemsLayout in a CollectionView. If ItemsLayout is initially set to Vertical, changing it to Horizontal causes the issue. If ItemsLayout is initially set to Horizontal, switching to Vertical leads to the same exception.

Steps to Reproduce

1. Launch the application. LayoutIssueSample.zip
2. Change the ItemsLayout to Horizontal List/Grid using the radio buttons.
3. Select a Header or Footer option after applying the ItemsLayout change.
4. The app crashes with a TargetInvocationException.
