• Windows Forms Bringing controls out from design-time

  I'm using standard DesignSurface for control design in my custom editor and I'm trying to serialize designed controls with my custom serializator that simply recursively parses the root component and emits custom serialization data for each and every component.

My serialization process cannot generically differentiate these design-time objects from real ones. The solution could be to remove the components from design-t ...Show All
