Gets a value that indicates whether the position of the mouse pointer corresponds to hit test results, which take element compositing into account.
Assembly: PresentationCore (in PresentationCore.dll)
Unlike IsMouseOver, this property is only true if the mouse pointer is over the literal element—as it is for a hit test. If the mouse pointer is instead over a child element, this property will be false. For most scenarios where you are not authoring controls, use IsMouseOver instead.
If the mouse is captured by this element, and this property is true at time of capture, this property will continue to return true until mouse capture is lost and the pointer is not over its bounds.
