How do I prevent the Designer-Grid from being drawn on a container control during design-time?

Override the DrawGrid property in the custom designer:

public class CustomContainerDesigner : ParentControlDesigner 
{ 
  protected override bool DrawGrid 
  { 
    get { return disableDrawGrid ? false : base.DrawGrid; } 
  } 
}
