If a child control has been made visible since the last layout operation, the P:System.Windows.Forms.Control.Visible property is affected. The P:System.Windows.Forms.LayoutEventArgs.AffectedProperty property is set to null if no value was provided when the M:System.Windows.Forms.Control.PerformLayout method was called.

The following code example uses the P:System.Windows.Forms.LayoutEventArgs.AffectedProperty and P:System.Windows.Forms.LayoutEventArgs.AffectedControl properties as T:System.Windows.Forms.LayoutEventHandler arguments to coordinate the size of a Windows form and its controls with various property changes to both the Windows form and the controls.
