The Web Parts control set calls this method after personalization data has been applied to the control. A control that tracks its change state should use this method to reset its internal state to indicate that subsequent property-setting methods should call erload:System.Web.UI.WebControls.WebParts.WebPart.SetPersonalizationDirty. By the time the ITrackingPersonalizable.EndLoad method is called, the Web Parts control set has completed any application of personalization data to the control. As a result, subsequent changes to the control's state should be considered valid indicators that the control has changed (is "dirty").
This method is also called when personalization data is applied after importing a Web Parts control.
