DeclarativeCatalogPartDesigner.GetDesignTimeHtml Method ()
Overrides the parent method to prevent rendering of the control.
Assembly: System.Design (in System.Design.dll)
If there is no WebPartsTemplate associated with the control, the designer displays the standard gray box with the class name and instance name of the control. Otherwise, no design-time rendering occurs at all because the check boxes and Web Parts titles are rendered by the CatalogPartChrome instead of the DeclarativeCatalogPart itself.
