For some reason I am getting ID row pop up in my AddEditReview.aspx file
When I look at the example on the book, it shows that there is no ID row.
When I open it up in the browser and leave ID empty while the other forms Title, Body, summary, GenreID filled according to the book and submit I get this:
Server Error in '/' Application.
Cannot insert the value NULL into column 'Id', table 'C:\BEGASPNET\SITE\SITE1\SITE1\APP_DATA\PLANETWR0X .MDF.dbo.Review'; column does not allow nulls. INSERT fails.
The statement has been terminated.
I have been trying at this for 3 hours. I would love some enlightened thoughts on this (please)
