Forces the control to apply layout logic to all its child controls.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The AffectedControl and AffectedProperty properties of the LayoutEventArgs created are set to a null reference (Nothing in Visual Basic) if no values were provided when the PerformLayout method was called.
The following code example demonstrates how to use the PerformLayout method. It also demonstrates ways in which the Layout event is raised. In this example, the Click event handler for Button1 explicitly calls PerformLayout. The Click event handler for Button2 implicitly calls PerformLayout. PerformLayout is also called when the form is loaded. Button3 returns the control to the state it was in when loaded. In each case, the Layout event is raised.
This is a complete example. To run the example, paste the following code in a blank form.
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
