When radPropertyGrid is grouped, we should check in IsCompatible() method that the item is not a PropertyGridGroupItem because the GroupItem is not compatible with the PropertyGridItem.

public class DefaultPropertyGridItemElement : PropertyGridItemElement
{

   public override bool IsCompatible(PropertyGridItemBase data, object context)
   {
      return (data is PropertyGridItem) && data.Label != "DbCounterState";
   }

}
