Disable rest of toolbar when command is clicked.

Using C#.NET in VS 2010.

I have a custom toolbar implementing BaseToolbar.  On the toolbar are commands, menus, and tools implementing BaseCommand, BaseMenu, and BaseTool.  When clicking on a tool that, for example, shows a form, I would like to have other tools on the toolbar disabled.  I have researched many leads I had for this problem, but I am coming up short.  Any suggestions would be appreciated!
