Restricting The Bullets Levels in WPF

Question

Hi,

How do i restrict the Bullets levels to max 3 level in a WPF/Win Forms. i.e the user should not be able to add more levels than 3.

I have downloaded "richtextboxinputpanel" from the MSDN site, where it uses "EditingCommands.ToggleBullets" for Bullets.

Thanks in Advance .
