Occurs when the element captures the mouse.

This interface is not intended for public implementation. For more information, see remarks for the IInputElement interface.
When an element captures the mouse, that element receives mouse input even if the cursor is outside its bounds. The mouse is typically captured in this manner only during drag-and-drop operations and retains capture until the drop action of the drag-and-drop operation occurs.
