invalidate() [1/6]

virtual void xtd::forms::control::invalidate ( ) const

virtual

Invalidates the entire surface of the control and causes the control to be redrawn.

Remarks

Calling the invalidate method does not force a synchronous paint; to force a synchronous paint, call the update method after calling the Invalidate method. When this method is called with no parameters, the entire client area is added to the update region.
