Parameters

designerHost

An IDesignerHost instance that is the designer host for the page.

controlText

The HTML markup for the control.

Return Value

The Control that controlText represents; otherwise, a null reference (Nothing in Visual Basic), if the parser cannot build the control.

Exception typeCondition

ArgumentNullException

A parameter is not valid.

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() );
