Gets a value indicating whether the mouse pointer is located over this element (including child elements in the visual tree). This is a dependency property.
Assembly: PresentationCore (in PresentationCore.dll)
Metadata properties set to true
Typically, controls are composited such that the various elements inside the control (the visual tree) will all report the mouse state for the containing control. For example, a ListBox style control will report as true if the mouse is anywhere over its geometry, including any ListBoxItem.
If this element captures the mouse, this property remains true until mouse capture is lost and the mouse pointer leaves the element bounds.
Some controls deliberately capture the mouse on certain actions that do not appear to directly involve the mouse. This can lead to being true even though the mouse has not apparently moved.
