The User Drawn Display Area event allows the developer to take over complete control of the presentation of the display area of the control.
The User Drawn Display Area event fires before the display area is painted. The event passes an e argument that contains the following custom properties …
· e.Graphics (of type Graphics): A handle to the graphics object responsible for drawing the control. Through the e.Graphics object the developer has access to the GDI+ methods for drawing objects to a display device.
· e.PaintDisplayArea (of type Boolean): Determines if the internal routines of the control should draw the Display Area. When the PaintDisplayArea property is set to False the control does not execute its internal paint routine and the developer has control over the painting of the Display Area.
· e.Rect (of type Rectangle): A rectangle representing the area being painted in the control. The rectangle is defined by an X,Y coordinate (top left of rectangle) and a width and height of the area being painted. All values are in pixels.
· e.Text (of type String): Determines the current text of the Display Area.
