Class NoHitTestDrawingVisual

NoHitTestDrawingVisual is a visual object that can be used to render vector graphics on the screen. The content is persisted by the system. Use this derived object instead of the base class DrawingVisual when you do not want the object to participate in hit-testing, as for example when you want to draw a solid background rectangle over selected cells in a grid but still want the hit-test to be passed down to the underlying cells when the user moves the mouse over the rectangle.
