Does Visual Basic.NET support the ClipControls property?
No. When your application is upgraded and this property is referenced in the code, it is left as-is and is marked with upgrade warnings. To correct this issue, you must replace references to the property with a call to the Graphics.SetClip method. By providing an event handler for the Paint event, you can access the Graphics object associated with the control that is going to be drawn. Using this object, the SetClip method can be called to specify a clipping region. This is a somewhat advanced technique that requires additional work; before writing custom drawing routines you should test the drawing performance of your upgraded application. The ClipControls property is used to improve performance in hardware that has limited capabilities. Modern high-performance computers and video cards are often sufficient to render displays without the need for clipping.
