Set and Get Textbox Value inside ascx Control from ASP.NET Page

Setting and getting Textbox value inside user control (ascx control) from aspx page is a usual practice in both simple and complex projects.
In this tutorial, we will
  • Create New User Control.
  • Add User Control in aspx Page.
  • Set Textbox Value inside User Control
  • Get Textbox value From User Control

Create New User Control

  1. Right Click on Project, Click Add New Item.
  2. A pop up window will be opened.
  3. Select Web User Control from list, change its Name to 'myControl' and click Add
  4. Two files will be added with name 'myControl.ascx' and 'myControl.ascx.cs'
Replace the code in 'myControl.ascx' file with following code.
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="myControll.ascx.cs" Inherits="Controls_myControll" %>
            Name :
            <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
            Age :
            <asp:TextBox ID="txtAge" runat="server"></asp:TextBox>
            Profession :
            <asp:TextBox ID="txtProfession" runat="server"></asp:TextBox>

Add following code in 'myControl.ascx.cs' File.
    public string Name
        get { return txtName.Text.ToString(); }
        set { txtName.Text = value; }
    public string Age
        get { return txtAge.Text.ToString(); }
        set { txtAge.Text = value; }
    public string Profession
        get { return txtProfession.Text.ToString(); }
        set { txtProfession.Text = value; }


Add User Control in aspx Page

  1. Create New aspx Page with name ‘PageForWebControl’.
  2. Open Design View and drag and drop user control on it. Some code will be added in 'PageForWebControl.aspx' page automatically. 
Page will look like this.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="PageForWebControl.aspx.cs" Inherits="PageForWebControl" %>

<%@ Register src="Controls/myControll.ascx" tagname="myControll" tagprefix="uc1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        <uc1:myControll ID="myControll1" runat="server" />   

Set Textbox Value inside User Control

Add following code snippet in Page Load Event of 'PageForWebControl.aspx' page to set Values of Textbox  inside User Control.
// Setting Values in ASCX Control
        myControll1.Name = "Waqas Ali";
        myControll1.Age = "24";
        myControll1.Profession = "Computer Scientist";

Get Textbox value From User Control

Add following code snippet in Page Load Event of PageForWebControl.aspx page to get values of Textbox from User Control.
        string _name = string.Empty;
        int _age = 0;
        string _profession = string.Empty;
// Getting Values from ASCX Control
        _name = myControll1.Name;
        _age = Convert.ToInt32(myControll1.Age);
        _profession = myControll1.Profession;

Now you are all done. Run Project and test your values.
