Notifies the System.Web.UI.HtmlControls.HtmlInputFile control that the state of the control has changed.
The System.Web.UI.HtmlControls.HtmlInputFile control implements the System.Web.UI.IPostBackDataHandler interface, which has two methods: System.Web.UI.IPostBackDataHandler.LoadPostData(string, System.Collections.Specialized.NameValueCollection) and System.Web.UI.IPostBackDataHandler.RaisePostDataChangedEvent. The System.Web.UI.IPostBackDataHandler.RaisePostDataChangedEvent method does not participate in the processing of the System.Web.UI.HtmlControls.HtmlInputFile control and is included to complete the interface implementation.
The HtmlInputFile.RaisePostDataChangedEvent method is used primarily by control developers to extend the functionality of the System.Web.UI.HtmlControls.HtmlInputFile control.
