I have an existing website, built in Visual Studio 2010, that I would like to integrate with a web application I wrote in ASP.NET/C# (also in VS2010). When I try to move the pages to the website (just dragging and dropping), the MyPage.aspx.designer.cs file doesn't stay in the 'group' of files. (.aspx, .aspx.cs)For reference, (if it matters), my application is an Online Application for my company, where people can apply online.Any help is appreciated!!-E[Update]: This is the error I get when trying to view an integrated page in the browser:\[code\]Line 1: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TheEnd.aspx.cs" Inherits="ApplicantEntry.TheEnd" %>Line 2: Line 3: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\[/code\]
