ControlDesigner::CreatePlaceHolderDesignTimeHtml Method

Provides a simple rectangular placeholder representation that displays the type and ID of the control.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

protected:
String^ CreatePlaceHolderDesignTimeHtml()

Return Value

Type: System::String
A string that contains design-time HTML markup providing basic information about the control.

Notes to Inheritors:

The typical design pattern is to try to get HTML markup through the associated control, and then if an error is encountered, call the GetErrorDesignTimeHtml method. If no markup is returned by the control, call the GetEmptyDesignTimeHtml method, which if it is not overridden to provide specific markup, calls the CreatePlaceHolderDesignTimeHtml method, which should contain information about the type and ID of the control.
