Retrieves the HTML markup that provides information about the specified exception.
Assembly: System.Design (in System.Design.dll)
The method is typically called, if an exception is thrown in the GetDesignTimeHtml method.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 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.
