ControlDesigner.OnControlResize Method

Note: This API is now obsolete. The non-obsolete alternative is OnComponentChanged.

Called when the associated Web server control has been resized in the design host at design time.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

[ObsoleteAttribute("The recommended alternative is OnComponentChanged(). OnComponentChanged is called when any property of the control is changed.")]
protected virtual void OnControlResize()


The OnControlResize method is obsolete. Use the OnComponentChanged method for equivalent control designer functionality.

The OnControlResize method typically is called only by the design-time environment when a user action causes the associated Web server control to be resized. The OnControlResize method might be called several times during a resizing process to display the updated size of the control before the resizing is completed. The width and height properties of the control are updated before the OnControlResize method is called.
