Sample code that illustrates the problem

Description of Problem:
When DataGridView row is selected it send following StateChanged (printed using : Console.WriteLine("State: " + e.StateChanged)):
State: Selected, Visible
State: Displayed, Selected, Visible
Whereas .NET Framework reports every state independently. As a result this condition doesn't work:
         if (e.StateChanged == DataGridViewElementStates.Selected)

Steps to reproduce the problem:
1. Launch sample application.
2. Click "Fill" button few times.
3. Select any row.

Actual Results:
Nothing happens.

Expected Results:
MessageBox should appear.

How often does this happen? 

Additional Information:
Mono's StateChange handling isn't compatible with .NET Frameworks.
