Joe,

>After I enter the remaining values I press my Next button I get the following error message:
>Cannot insert the value NULL into column 'VisitorType', table 'StellarVisiTrak.dbo.VisitorTypes'; column does not allow nulls. INSERT fails.

Is "VisitorTypes" specified as the TableName for the VisitorType business object? Is the "VisitorTypes" column bound to a user interface control? In Windows Forms binding back occurs automatically. When a user enters a value and the control loses focus the value is stored back to the specified DataColumn.

If all of this is set up correctly, it's possible you're running into an EndEdit issue with Windows Forms. Check out the MM .NET Dev Guide topics "AutoEndEdit: Automatically Ending Pending Edits" and "Why doesn't my data get saved to the back end?".
