Parameters

constraint: Size

An upper limit Size that should not be exceeded.

Returns

Size

Remarks

When scrolling, VirtualizingStackPanel does not grow in layout size, but effectively adds its descendants on a z-plane, which is normally clipped by a parent element (typically a ScrollContentPresenter) to the size of the stack.
