asp.net C# - Login.aspx issues

Posted 01 August 2011 - 08:21 PM

The issues started when I put the loginview,AnonymousTemplate and LoggedInTemplate status in the login.aspx page. The code was working fine before then it but if you login and then went back to login.aspx the login form would still show, so i put the loginview now but in the login.aspx.cs code behind page the textboxs and labels now give me an error. Is there a way I can find the aspx controls in the code behind file with the loginview?


<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.master" AutoEventWireup="true" CodeFile="login.aspx.cs" Inherits="login" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
    <style type="text/css">
label {
  width:130px;    /*Or however much space you need for the formís labels*/
    float:left;
}
i 
{
    color:Red;
}
</style>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
    <div style="margin-left: 300px;margin-top: 100px">
<table style="border: 2px solid #000;background-color:#CCFF66;">
    
<tr>
<th>Homezid.com Login</th></tr>
<tr>
<td><label><i>*</i> Email</label><asp:TextBox ID="email" BackColor="#FFFF99"  runat="server"></asp:TextBox></td></tr>
<tr>
<td><label><i>*</i> Password</label><asp:TextBox ID="password" TextMode="Password"  BackColor="#FFFF99" runat="server"></asp:TextBox><br /></td></tr>
<tr><td align="center">
    <asp:Button ID="Loginsite" runat="server" Text="Login" 
        onclick="Loginsite_Click" /></td>
    </tr>
<tr><td>
    <asp:Label ID="errormessage" ForeColor="Red" runat="server" Text=""></asp:Label></td>
    </tr>
<tr><td>
    <asp:HyperLink ID="HyperLink1" NavigateUrl="~/register.aspx" runat="server">Register Account</asp:HyperLink></td>
    <td><asp:HyperLink ID="HyperLink2" runat="server">Forgot Password?</asp:HyperLink></td>
    </tr>
</table>
</div>
</AnonymousTemplate>
    <LoggedInTemplate>
        <asp:LoginStatus ID="LoginStatus1" runat="server" />

        command = new SqlCommand("SELECT email,password FROM registration WHERE [email]=@email AND [password]=@password",connect);
        command.Parameters.AddWithValue("@email", email.Text);
        command.Parameters.AddWithValue("@password", password.Text);
        connect.Open();
        reader = command.ExecuteReader(Commandbehavior.CloseConnection);
        if (email.Text=="" || password.Text == "")
        {
            
            errormessage.Text = " Please fillout the email and/or password";
        }
        else if (reader.Read())
        {
            FormsAuthentication.RedirectFromLoginPage(email.Text, true);
            Response.Redirect("edit.aspx");

        }


        else
        {
             errormessage.Text= "Email or Password is invalid";
        }
        connect.Close();
       
        
    }
}
