Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public function get Region () : Region 
public function set Region (value : Region)

Property Value

Type: System.Drawing.Region
The window Region associated with the control.

The window region is a collection of pixels within the window where the operating system permits drawing. The operating system does not display any portion of a window that lies outside of the window region. The coordinates of a control's region are relative to the upper-left corner of the control, not the client area of the control.

NoteNote:

The collection of pixels contained with the region can be noncontiguous.

The following code example demonstrates how to use the Region property by creating a round button. To run the example, paste the following code in a form containing a button called roundButton. This example requires that the Paint event is connected to the event handler defined in the example.
