Code:
Go to your solution explorer and click the Show ALL button.
Then expand your Form1 and find the Designer.
When you open the designer you'll see this code:
[php]Inherits System.Windows.Forms.Form[/php]
Change it to:
[php]Inherits DevComponents.DotNetBar.Office2007RibbonForm[/php]
You might have to refer to this thread a few times to remember it, but you'll soon know it off by heart like me.
