This 4-minute video demonstrates creating a form region in Outlook with controls that are bound to Outlook data, and then importing the form region into a Visual Studio 2008 Beta 2 Outlook add-in project.
After the form region is in Visual Studio, you can add managed code to handle the events, but the data is still coming from Outlook. If you create the entire form region from scratch in Visual Studio, you can’t bind the controls to Outlook data.
You can find the steps and the code on MSDN:
