Popup.MeasureOverride(Size) Method

Definition

Determines the required size of the Popup content within the visual tree of the logical parent.

protected:
 override System::Windows::Size MeasureOverride(System::Windows::Size availableSize);
protected override System.Windows.Size MeasureOverride (System.Windows.Size availableSize);
override this.MeasureOverride : System.Windows.Size -> System.Windows.Size
Protected Overrides Function MeasureOverride (availableSize As Size) As Size

Parameters

availableSize
Size

The available size that this element can give to the child. You can use infinity as a value to indicate that the element can size to whatever content is available.

Returns

A Size structure that has the Height and Width properties both equal to zero (0).

Remarks

This method always returns a Size that has a width and height of zero (0), because Popup content is not located in the visual tree of its logical parent or PlacementTarget. The child content is created in a different window that has its own visual tree.
