Page::RegisterRequiresPostBack Method (Control^)
Registers a control as one that requires postback handling when the page is posted back to the server.
Assembly: System.Web (in System.Web.dll)
The control to be registered must implement the IPostBackDataHandler interface or an HttpException is raised. When implemented by a control, the IPostBackDataHandler interface enables handling of post back data and raising of any post back data changed events. For more information on the server control event model, see ASP.NET Web Forms Server Control Event Model.
Register controls with the page at or before the Page_PreRender event of the page life cycle.
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
