Control.Layout Event

Occurs when a control should reposition its child controls.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event LayoutEventHandler Layout

The Layout event occurs when child controls are added or removed, when the bounds of the control changes, and when other changes occur that can affect the layout of the control. The layout event can be suppressed using the SuspendLayout and ResumeLayout methods. Suspending layout enables you to perform multiple actions on a control without having to perform a layout for each change. For example, if you resize and move a control, each operation would raise a Layout event.

For more information about handling events, see Handling and Raising Events.

The following code example centers a Form on the screen in the Layout event. This will keep the form centered as the user resizes it. This example requires that you have created a Form control.

   private void MyForm_Layout(object sender, System.Windows.Forms.LayoutEventArgs e)
   {
      // Center the Form on the user's screen everytime it requires a Layout. 
      this.SetBounds((Screen.GetBounds(this).Width/2) - (this.Width/2),
          (Screen.GetBounds(this).Height/2) - (this.Height/2),
		  this.Width, this.Height, BoundsSpecified.Location);	
   }
