I am trying to create a webapp using C# and ASP. I have created a login page using forms authentication. I am kind of new to this, so please be mindful as to how you respond to me. I wish that there was a way to just simply upload the Project solution file because I may be having issues with the Web.config file as well as the login.aspx file. I am using Visual Studios 2019 to accomplish this. Please HELP

What I have tried:

HTML

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="AOIWebApp01.Login" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div style="font-family:Arial">
<table style="border: 1px solid black">
    <tr>
        <td colspan="2">
            Please Enter Your Credentials
        </td>
    </tr>
    <tr>
        <td>
            User Name
        </td>    
        <td>
            :<asp:TextBox ID="txtUserName" runat="server">
            </asp:TextBox>
        </td>    
    </tr>
    <tr>
        <td>
            Password
        </td>    
        <td>
            :<asp:TextBox ID="txtPassword" TextMode="Password" runat="server">
            </asp:TextBox>
        </td>    
    </tr>
    <tr>
        <td>
                    
        </td>    
        <td>
            <asp:Button ID="btnLogin" runat="server" Text="Login" OnClick="btnLogin_Click" />
        </td>    
    </tr>
    <tr>
        <td colspan="2">
            <asp:Label ID="lblMessage" runat="server" ForeColor="Red">
            </asp:Label> 
        </td>

    </tr>
</table>
<br />
<a href="Registration/Register.aspx">Click here to register</a> 
if you do not have a user name and password.
        </div>
    </form>
</body>
</html>

Login.aspx.cs

C#

using System;
using System.Web.Security;

namespace AutOSImageWeb01 {

	public partial class Login : System.Web.UI.Page {

		protected void Page_Load(object sender, EventArgs e) {}
	
		[Obsolete]
		protected void btnLogin_Click(object sender, EventArgs e) {
			if (FormsAuthentication.Authenticate(txtUserName.Text, txtPassword.Text)) {
				FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, false);
			}
			else {
				lblMessage.Text = "Invalid Username and/or Password.";
			}
		}
	}
}

The form looks to be OK, but without seeing the code on Login.aspx.cs it is hard to tell if it is ok; particularly the btnLogin_Click method which would read the values from the form and then verify/validate

Derrick Chandler 31-Mar-20 9:39am

Here is the code for the login.aspx.cs file:

using System;
using System.Web.Security;

namespace AutOSImageWeb01
{
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}

[Obsolete]
protected void btnLogin_Click(object sender, EventArgs e)
{
if (FormsAuthentication.Authenticate(txtUserName.Text, txtPassword.Text))
{
FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, false);
}
else
{
lblMessage.Text = "Invalid Username and/or Password.";
}
}
}
}

RedirectFromLoginPage should take the user to the page they requested in the first place.
If you want this to do something different, comment that line out and add in your own Redirect routine

Derrick Chandler 31-Mar-20 12:23pm

I have done so in the followng:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;

namespace AOIWebApp01
{
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnLogin_Click(object sender, EventArgs e)
{

if (txtUserName.Text == "enduser1, enduser2, enduser3")
{
Response.Redirect("client.aspx");
}

else if (txtUserName.Text == "ITAdmin1, ITAdmin2, ITAdmin3")
{
Response.Redirect("admin.aspx");
}

}

}

}

You forgot to Authenticate them first, and then this should only be done IF authentication was successful

Solution 1

In your login code after you validate the username and password you can use Response.Redirect("urltogoto"); to take them to a new page.

Would I put the Response.Redirect line into the web.config file for the login.aspx fie? Forgive me as I am somewhat new to this.

ZurdoDev 31-Mar-20 9:49am

It would be in the code behind file. There is no code in a webconfig or really even in an aspx file. Code goes in your .cs (C sharp) file.

Derrick Chandler 31-Mar-20 10:13am

Gotcha. I want to do this based on a certain username and password. From the login page, if the users are end users, they will be redirected to a client page, but if they are IT Admins, they will be redirected to an Admin page. I want to do this without having to use an SQL database.

ZurdoDev 31-Mar-20 10:22am

Then you have to hardcode everything, which is a really bad idea. But then you can do something like

... code to verify username and password...
...
if (Group == "IT Admins") {
Response.Redirect("somepage.aspx");
}
else if (Group == "Users")
{
Response.Redirect("SomeOtherPage.aspx");
}
...
etc.

Derrick Chandler 31-Mar-20 10:32am

Where would I specify the group in VS 2019? If you're not too busy, could we possibly do a TeamViewer session?

ZurdoDev 31-Mar-20 10:36am

No, I am way too busy. But this does not sound like something you should be doing. You really need to understand development more.

There is no built-in group thing, unless you are talking about Active Directory groups. But we would need more info from you.

The problem is you are going to have one question after another after another. You really need to either pay someone or learn some basics of coding.

Derrick Chandler 31-Mar-20 11:01am

If there was availability via Team Viewer, there would NOT be any further questions. I did what you suggested and now I am still having other things go wrong. This is for a team project for school and I am more of a Network Admin guy, rather than a coder.

I will not pay anyone to do anything. If you cannot help me any longer, I will either figure it out, or ask someone else on this site. Good Day.

ZurdoDev 31-Mar-20 11:03am

As you said "I am still having other things go wrong."

We are all here to help but we can't spend all day doing your work.

But I suggest since you have gotten past this, to open a new question with whatever specific step you are stuck on.

Derrick Chandler 31-Mar-20 11:36am

Because of the resolution that you gave me. That's why I said that. I never asked you or anyone else to do my work for me, so we will NOT go there. Do not respond to me any more or I will report you.

ZurdoDev 31-Mar-20 12:03pm

You have clearly gotten upset by something I said and I'm not sure why. I'm taking my time to volunteer to help you. I'm not sure why that bothers you.

Your original question is how to redirect users based on something. I have answered that based on the information you have provided me.

Derrick Chandler 31-Mar-20 12:27pm

I appreciate the volunteering to help, but you are saying things like "this is not for you", or "i cant do your work for you" (I am paraphrasing just in case you feel the need to correct me). I never asked you to do my work for me. If you would have read in the initial question where I stated that I am kind of new to this, you would understand my reason for frustration.

ZurdoDev 31-Mar-20 12:29pm

I certainly understand your reason for frustration. But you also need to understand that you are not just asking one simple question where we can answer it and then you move on. Being new means you need a lot of hand-holding and the questions you are asking makes me suggest you hire somebody. It's not meant to be personal.

Derrick Chandler 4-Apr-20 17:58pm

I actually do not need any hand holding. I was able to fix this issue. There will be another question. Please feel free to skip it or just flat out not answer it. Thank you.

ZurdoDev 4-Apr-20 19:15pm

There is no need to be rude. I answered your question and would be happy to answer another one anytime.

Derrick Chandler 19-Apr-20 13:13pm

I agree. There was no need for EITHER of use to be rude. Contrary to what you may believe, there was rudeness on both parts. Take care of yourself and stay healthy.
