Gets or sets a value indicating whether the element will be captured in pointer pressed event (MouseLeftButtonDown in SL and WPF and PointerPressed in UWP) or in the first pointer move event (MouseMove in SL and WPF and PointerMoved in UWP).Capturing the element on mouse down will cause Click, DoubleClick and MouseLeftButtonUp events not to be fired in sub-elements (nested elements in the visual tree), whereas capturing the element on the first mouse move can make it difficult for final users to drag small elements quickly.
