I have a set of ASPX files (with c#) on an intranet which work fine when used. I can copy the files onto my machine under inetpub and they still work under //localhost from the browser. However if I take any file and save it (Using WebMatrix) even if I do not change any code then I get an error:

 CS0246: The type or namespace name 'DataGrid1' could not be found (are you missing a using directive or an assembly reference?)

But I get different errors for any file I change.

Is it a permissions things? I have admin permissions.


Urgent help appreciated from any gurus out there!

Thanks
