6/25/2015 - By Pranav Singh 0

This article I will show you how you can pass multiple parameters in querystring or url in asp.net using c#.net.


<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm9.aspx.cs" Inherits="WebApplication2.WebForm9" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Asp.Net Pass Multiple Parameters in QueryString or URL in Asp.Net Using C#.Net</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Submit" onclick="Button1_Click" />
    </div>
    </form>
</body>
</html>

Now add the .cs code.

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

namespace WebApplication2
{
    public partial class WebForm9 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Redirect("WebForm10.aspx?FirstName=John&LastName=Mathu&Rank=20");
        }
    }
}

In above code I have passed the request querystring value in url.

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

namespace WebApplication2
{
    public partial class WebForm9 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Redirect("WebForm10.aspx?FirstName=John&LastName=Mathu&Rank=20");
        }
    }
}

Now on other page add the add the below code to retrieve the value passed in url.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm10.aspx.cs" Inherits="WebApplication2.WebForm10" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Result</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
      First Name : <asp:Label ID="lblFname" runat="server" Text="Label"></asp:Label><br />
       Last Name :<asp:Label ID="lblLname" runat="server" Text="Label"></asp:Label><br />
       Rank :<asp:Label ID="lblRank" runat="server" Text="Label"></asp:Label><br />
    </div>
    </form>
</body>
</html>

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

namespace WebApplication2
{
    public partial class WebForm10 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //FirstName=John&LastName=Mathu&Rank=20
            if (Request.QueryString["FirstName"] != null)
            {
                lblFname.Text = Request.QueryString["FirstName"].ToString();
            }
            if (Request.QueryString["LastName"] != null)
            {
                lblLname.Text = Request.QueryString["LastName"].ToString();
            }
            if (Request.QueryString["Rank"] != null)
            {
                lblRank.Text = Request.QueryString["Rank"].ToString();
            }
        }
    }
}

In above code I have checked the url value and display into the page. Now we have done run the application to check the output.


Now click on button. As we click on button break pint will hit and we will get the value.




Here is the URL



Now press F5 to see the final output.
