How to provide name to the TextBox in C#?

In Windows forms, TextBox plays an important role. With the help of TextBox, the user can enter data in the application, it can be of a single line or of multiple lines. In TextBox, you are allowed to assign a name to the TextBox control with the help of Name property of the TextBox. The default value of this property is an empty string. In Windows form, you can set this property in two different ways: 1. Design-Time: It is the simplest way to set the Name property of the TextBox as shown in the following steps:

• Step 1: Create a windows form. As shown in the below image: Visual Studio -> File -> New -> Project -> WindowsFormApp
• Step 2: Drag the TextBox control from the ToolBox and drop it on the windows form. You can place TextBox anywhere on the windows form according to your need. As shown in the below image:
• Step 3: After drag and drop you will go to the properties of the TextBox control to set the Name property of the TextBox. As shown in the below image: Output:

2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the Name property of the TextBox programmatically with the help of given syntax:

public string Name { get; set; }

Here, the value of this property is of System.String type. Following steps are used to set the Name property of the TextBox:

• Step 1 : Create a textbox using the TextBox() constructor provided by the TextBox class.

// Creating textbox
TextBox Mytextbox = new TextBox();

• Step 2 : After creating TextBox, set the Name property of the TextBox provided by the TextBox class.

// Set Name of the textbox
Mytextbox1.Name = "text_box1";

• Step 3 : And at last add this textbox control to form using Add() method.

// Add this textbox to form
this.Controls.Add(Mytextbox1);

• Example:

CSharp

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp2 {

public partial class Form1 : Form {

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // Creating and setting the properties of Lable1
        Label Mylablel1 = new Label();
        Mylablel1.Location = new Point(96, 54);
        Mylablel1.Text = "Enter First Name";
        Mylablel1.AutoSize = true;
        Mylablel1.BackColor = Color.GreenYellow;

        // Add this label to form
        this.Controls.Add(Mylablel1);

        // Creating and setting the properties of TextBox1
        TextBox Mytextbox1 = new TextBox();
        Mytextbox1.Location = new Point(187, 51);
        Mytextbox1.BackColor = Color.GreenYellow;
        Mytextbox1.AutoSize = true;
        Mytextbox1.Name = "text_box1";

        // Add this textbox to form
        this.Controls.Add(Mytextbox1);

        // Creating and setting the properties of Lable1
        Label Mylablel2 = new Label();
        Mylablel2.Location = new Point(96, 102);
        Mylablel2.Text = "Enter Last Name";
        Mylablel2.AutoSize = true;
        Mylablel2.BackColor = Color.GreenYellow;

        // Add this label to form
        this.Controls.Add(Mylablel2);

        // Creating and setting the properties of TextBox2
        TextBox Mytextbox2 = new TextBox();
        Mytextbox2.Location = new Point(187, 99);
        Mytextbox2.BackColor = Color.GreenYellow;
        Mytextbox2.AutoSize = true;
        Mytextbox2.Name = "text_box2";

        // Add this textbox to form
        this.Controls.Add(Mytextbox2);
    }
}
}
