Assembly: System.Design (in System.Design.dll)
Normally, the method is not overridden in derived designers. The base class causes the design host to call the SetEditableDesignerRegionContent method for the region. Override the method when custom data is required for the control before calling SetEditableDesignerRegionContent method.
Use the method to insert HTML markup into a region of the control.
