Can't change the column properties in a table in a database in Visual Web Developer 2010 Express MVC

Question

When I try to edit the Identity Specification from No to Yes there isn't a way to do so. No drop-down arrow or any way to edit the text. How can I change it so that I can actually change the value to 'Yes'?

Answer 1

I found that the problem was in fact that I had set the data type to a nvarchar() instead of int.
