Control.SizeChanged Event

Occurs when the Size property value changes.

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

member SizeChanged : IEvent<EventHandler,
    EventArgs>

It is preferable to use the Layout event to handle custom layouts. The Layout event is raised in response to Resize events, but also in other conditions when layout might need to be applied.

This event is raised if the Size property is changed by either a programmatic modification or user interaction.

For more information about handling events, see Consuming Events.

The following code example demonstrates the SizeChanged event. An instance of a Button control has been provided that can be scaled both horizontally and vertically. A NumericUpDown instance provides the horizontal and vertical scale value. The Button instance named OK is used to set the scale values for the Button control instance. Whenever the size of the control changes, the event handler associated with the SizeChanged event of the control is called. This event handler displays a message box indicating that the size of the control has changed.
