Edit DataGridView via Designer in inherited UserControl

I created a UserControl with a Button, a TextBox and a DataGridView. I set the modifiers of all controls to public.

Now If I inherit from that UserControl, I can modify the TextBox and the Button via Designer (move around, change properties) just as I expected. But for the DataGridView all properties are disabled.

Is there any reason, why I can't modify a DataGridView via the Designer in an inh开发者_开发百科erited UserControl?

Found a solution here: http://adamhouldsworth.blogspot.com/2010/02/winforms-visual-inheritance-limitations.html

In short:

1. Add a reference to System.Design

2. Inherit from DataGridView with this code:

   [Designer(typeof(ControlDesigner))]
   public class InheritableDataGridView : DataGridView
   {
       public InheritableDataGridView()
           : base()
       { }
   }
   

3. ???
4. Profit!!!
