Button in C#

A Button is an essential part of an application, software, or webpage. .NET Framework, the Button class is used to represent Windows button control and it is inherited from the ButtonBase class. It is defined under System.Windows.Forms namespace.

It allows users to interact with applications. Clicking an exit button closes the app, for example. Buttons enable actions like submitting or downloading, varying in appearance and reusable across programs.

Ways to Create a Button in Windows Forms

There are mainly two ways to create a button in Windows forms which are mentioned below.

• Drag and drop (Design-Time)
• Custom Button (Run-Time)

Drag and drop (Design-Time)

This is the easiest way to create a button in Windows Forms using Visual Studio we just have to open the toolbox and drag and drop the button on the form in the designer and further we can change the appearance of the button using the properties. Follow these steps to create a button.

Step 1: Locate the project in Visual Studio. In this example, we are using the default project name, Form1. Open the form in the editor to modify it further.

In the image, we have two files that are open one Design and there is Form1.cs these two play a major role. We use the Form 1.cs file for the custom logic.

Step 2: Now open a Toolbox go to the view > Toolbox or ctrl + alt + x.

Step 3. Now open the Common Controls section, then drag and drop a button onto the form where you want it to be placed.

Step 4. Now open the properties of the button press right-click on the button and it will open the properties solution explorer now we can change the button name to Click here.

Now we are changing the Text property from button1 to Click Here.

Step 5: We can change the appearance and the behaviour of the button using the properties.

Output:

Custom Button (Run-Time)

In this method we are going to modify the Form1.cs file and add custom code modification in C# to change the appearance of the button according to our requirements. Follow these step by step process.

Step 1: Create a button using the Button() constructor provided by the Button class.

// Creating Button using Button class

Button MyButton = new Button();

Step 2: After creating the Button, set the properties of the Button provided by the Button class.

// Set the location of the button

Mybutton.Location = new Point(225, 198);

// Set text inside the button

Mybutton.Text = "Submit";

// Set the AutoSize property of the button

Mybutton.AutoSize = true;

// Set the background color of the button

Mybutton.BackColor = Color.LightBlue;

// Set the padding of the button

Mybutton.Padding = new Padding(6);

// Set font of the text present in the button

Mybutton.Font = new Font("French Script MT", 18);

Step 3: And last add this button control to form using the Add() method.

// Add this Button to form

this.Controls.Add(Mybutton);

Step 4: Now double-click on the button in Design and it will open the Form cs file where code is written in C#. Here the program file is Form 1.cs Now write this code in Form1.cs file

Form1.cs file:

namespace WinFormsApp1 {
public partial class Form1 : Form {
    public Form1() { InitializeComponent(); }

    private void Form1_Load(object sender, EventArgs e)
    {
        // Creating and setting the properties of label
        Label l = new Label();
        l.AutoSize = true;
        l.Text = "Do you want to submit this project?";
        l.Location = new Point(222, 145);
        l.Font = new Font("French Script MT", 18);
        // Adding this label to form
        this.Controls.Add(l);

        // Creating and setting the properties of Button
        Button Mybutton = new Button();
        Mybutton.Location = new Point(225, 198);
        Mybutton.Text = "Submit";
        Mybutton.AutoSize = true;
        Mybutton.BackColor = Color.LightBlue;
        Mybutton.Padding = new Padding(6);
        Mybutton.Font = new Font("French Script MT", 18);

        // Adding this button to form
        this.Controls.Add(Mybutton);

        // Creating and setting the properties of Button
        Button Mybutton1 = new Button();
        Mybutton1.Location = new Point(360, 198);
        Mybutton1.Text = "Cancel";
        Mybutton1.AutoSize = true;
        Mybutton1.BackColor = Color.LightPink;
        Mybutton1.Padding = new Padding(6);
        Mybutton1.Font = new Font("French Script MT", 18);

        // Adding this button to form
        this.Controls.Add(Mybutton1);
    }

    private void button1_Click(object sender, EventArgs e)
    {
    }
}
}

Output:

Properties of Button

These are the important properties of the button
