The ParseControl method accesses the string representing the register directives on the ASP.NET Web page using the services of the designer host. Designer host services are acquired through the ReferenceManager property of the RootDesigner object, or if that is not available, the IWebFormReferenceManager service.

The ParseControl method throws an exception if the parser cannot build the control.

The following code example shows how to create a control from HTML markup text. This code example is part of a larger example provided for the ControlParser class.

// Create a Web control from the persisted control String*.
System::Web::UI::Control^ ctrl = ControlParser::ParseControl( host, inputForm->tbox->Text->Trim() );
