Occurs when this element loses mouse capture.
Assembly: PresentationCore (in PresentationCore.dll)
When an element captures the mouse, it receives mouse input even if the pointer is outside its bounds. The mouse is typically captured only during drag-and-drop operations.
Because this event uses bubbling routing, the element that loses capture might be a child element instead of the element where the event handler is actually attached. Check the Source in the event data to determine the actual element that lost capture.
This event creates an alias for the Mouse.LostMouseCapture attached event for this class, so that is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying Mouse.LostMouseCapture attached event and receive the same event data instance.
