VirtualizingStackPanel.MeasureOverride(Size) Method

Definition

Measures the child elements of a VirtualizingStackPanel in anticipation of arranging them during the ArrangeOverride(Size) pass.

C#
protected override System.Windows.Size MeasureOverride(System.Windows.Size constraint);

Parameters

constraint
Size

An upper limit Size that should not be exceeded.

Returns

The Size that represents the desired size of the element.

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.
