My program was working fine and after making some changes I get this error when I try to bring up the default.aspx page. all other pages come up fine. Does anybody have an idea as to why?

Hi there,

Since this is not related to my book directly, try posting questions like this one in a general ASP.NET 4 category from this list: http://p2p.wrox.com/asp-net-4-539/

That said, your _Default designer class is missing the Inherits attribute that makes it inherit System.Web.UI.Page. Check out the differences between the last two files you posted.

Cheers,

Imar

I looked at the last two programs I have listed as you said, and I'm not sure what to look for. I compared these default files with another program and they look almost similar. I posted this also in the general section of P2P...so hopefully someone there can help me.

Thanks for trying, much appreciated,
Fred

Oh, my bad. I thought that the designer file had to inherit Page explicitly as well but since it's a partial class, it doesn't have to.

It looks like iGrades._Default in the markup is not a valid type, which could indicate the (root) namespace of the project has changed. To find out what it needs to be, add a new Web Form to the project and look at the Inherits in markup up.

Cheers,
