The ControlDesigner.OnAutoFormatApplied(DesignerAutoFormat) method is called after a System.Web.UI.Design.DesignerAutoFormat object has applied a predefined format to the associated control. A System.Web.UI.Design.DesignerAutoFormat object defines the automatic formatting scheme name and style settings that are applied to the control.

Classes deriving from the System.Web.UI.Design.ControlDesigner class override the ControlDesigner.OnAutoFormatApplied(DesignerAutoFormat) method to perform additional processing when an automatic formatting scheme is applied to the associated control.
