Invalidates the specified region of the current View (adds it to the control's update region which will be repainted during the next paint operation), and sends a paint message to the scheduler control.
public virtual void Invalidate( Rectangle bounds )
Public Overridable Sub Invalidate( bounds As Rectangle )
A Rectangle structure that specifies the region to paint.
The Invalidate method does not force a synchronous paint. To force a synchronous paint, call the Update method of your scheduler control after calling the Invalidate method.
A View is automatically invalidated when necessary. You can force invalidation manually to implement specific behavior, such as custom painting of scheduler elements.
