Textbox Data Transfer One Page to Another Page Using Various ASP.NET Techniques

We will see techniques for TextBox value retrievals from one page to another page.

Technique 1: Data Transfer with Cookies

In this example the TextBox data transfer uses cookies as in the following.

Form 1

Design: Add FillInfo.aspx.

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

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <div>
        <asp:Label ID="Label1" runat="server" Text="User name : "></asp:Label>
        <asp:TextBox ID="txtUsername" runat="server"></asp:TextBox>
        <asp:Button ID="btnsend" runat="server" Text="Send Text Value Next Page" OnClick="btnsend_Click" />
    </div>
</asp:Content>

Code: FillInfo.aspx.cs.

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

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

    }
    protected void btnsend_Click(object sender, EventArgs e)
    {
        HttpCookie Cookie = new HttpCookie("Username");
        Cookie.Value = txtUsername.Text;
        Cookie.Expires = DateTime.Now.AddHours(1);
        Response.Cookies.Add(Cookie);
        Response.Redirect("ShowInfo.aspx");
    }
}

Form 2

Design: Add ShowInfo.aspx.

Code: ShowInfo.aspx.cs.

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

public partial class UI_Cookies_ShowInfo : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.Cookies["Username"] != null)
        {
            Response.Write(Request.Cookies["Username"].Value.ToString());
        }
    }
}

Now run the FillInfo.aspx page and fill in the user name as in the following:

Technique 2: Data Transfer with Application Variable

In this example the TextBox data transfer uses an application variable as in the following.

First create two forms.

From 1

Design: FillApplicationVariable .aspx.

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

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <div>
        <asp:Label ID="Label1" runat="server" Text="User name : "></asp:Label>
        <asp:TextBox ID="txtUsername" runat="server"></asp:TextBox>
        <asp:Button ID="btnsend" runat="server" Text="Send Text Value Next Page" OnClick="btnsend_Click" />
    </div>

</asp:Content>

Code: FillApplicationVariable .aspx.cs.

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

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

    }
    protected void btnsend_Click(object sender, EventArgs e)
    {
        Application["Username"] = txtUsername.Text;
        Response.Redirect("ShowApplicationVariable .aspx");
    }
}

Form 2

Design: Add ShowApplicationVariable .aspx.

Code: ShowApplicationVariable .aspx.cs.

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

public partial class UI_Appvariable_ShowApplicationVariable_ : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Application["Username"] != null)
        {
            string Name = Application["Username"].ToString();
            Response.Write(Name);
        }
    }
}

Now run the form in the browser and fill in the application variable's value in the TextBox as in the following.

Technique 3: Data Transfer with Session Variable

In this example the TextBox data transfer uses a session variable as in the following.

Form 1

Design: Add FillSessionName.aspx.

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

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <div>
        <asp:Label ID="Label1" runat="server" Text="User name : "></asp:Label>
        <asp:TextBox ID="txtUsername" runat="server"></asp:TextBox>
        <asp:Button ID="btnsend" runat="server" Text="Send Text Value Next Page" OnClick="btnsend_Click" />
    </div>

</asp:Content>

Code: FillSessionName.aspx.cs.

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

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

    }
    protected void btnsend_Click(object sender, EventArgs e)
    {
        Session["Username"] = txtUsername.Text;
        Response.Redirect("ShowSessionName.aspx");
    }
}

Form 2

Design: Add ShowSessionName.aspx.

Code: ShowSessionName.aspx.cs.

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

public partial class UI_Session_ShowSessionName : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["Username"] != null)
        {
            Response.Write(Session["Username"].ToString());
        }
    }
}

Now run the form in a browser and fill in the session variable value in TextBox as in the following.

Technique 4: Data Transfer with Query String

In this example the TextBox data transfer in the next page of the browser URL path using a Query String is as in the following.

Form 1

Design: Add FillStringValue.aspx.

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

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <div>
        <asp:Label ID="Label1" runat="server" Text="User name : "></asp:Label>
        <asp:TextBox ID="txtUsername" runat="server"></asp:TextBox>
        <asp:Button ID="btnsend" runat="server" Text="Send Text Value Next Page" OnClick="btnsend_Click" />
    </div>

</asp:Content>

Code: FillStringValue.aspx.cs.

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

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

    }
    protected void btnsend_Click(object sender, EventArgs e)
    {
        Response.Redirect("ShowStringValue.aspx?Username=" + txtUsername.Text);
    }
}

Form 2

Design: Add ShowStringValue.aspx.

Code: ShowStringValue.aspx.cs.

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

public partial class UI_QueryString_ShowStringValue : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string Name = Request.QueryString["Username"].ToString();
        Response.Write(Name);
    }
}

Now run the form in a browser and fill in a string variable value into the TextBox as in the following.
