i know i know... i minimized the window and forgot where i was at... i thought i was making a thread but i was looking up the answer to his question.

use:

<%@ Page Language="C#" AutoEventWireUp="true" CodeFile="FirstPageCodeBehind.aspx.cs" Inherits=classname %>

Code File is self explanitory but Inherits links you to the class in the code file. just type a class name.
