Could not load type 'WebApplication3.itemdetails'.

[Guest]

On my application's first page, the codebehind statement is set as"

<%@ Page language="vb" Codebehind="WebForm1.aspx.vb" AutoEventWireup="false"
Inherits="WebApplication3.WebApplication3.WebForm1" %>

and works fine (although I dont know why webaplication3 has to be there
twice, it just does)

However, I have a details page defined with

<%@ Page language="vb" Codebehind="itemdetails.aspx.vb"
AutoEventWireup="false"
Inherits="WebApplication3.WebApplication3.itemdetails" %>

that gives the Could not load type 'WebApplication3.itemdetails'. error

Also tried the inherits with a single WebApplication3, to no avail. any
ideas TIA
