The code behind not matched to the design.For example , it gives me an error
Login1 cannot be found in the current context
And when I try to add event to the login it is written as the following:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication4._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Any idea to solve this problem , the big problem is that the code doesn't see the design and vise verse
Firstly :
Make sure that your name space is :
WebApplication4
and the class name is:
_Default
in your code behind file.like this:
namespace WebApplication4
{
public partial class _Default : System.Web.UI.Page
{
}
}
secondly:
Make sure the consistency of the .aspx.designer.cs file.
I mean make sure that there is a reference of your control in this file .like this:
protected global::System.Web.UI.WebControls.Login Login1;
and tell us which Visual studio version does u use.
It sounds like the designer.cs file is out of sync. If you go into the designer.cs file, you can declare the control, like this:
/// <summary>
/// Login1 control.
/// </summary>
/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
/// </remarks>
protected global::System.Web.UI.WebControls.Login Login1;
You might also try cutting and pasting the markup, so the designer registers all of the controls.
