C# Windows Forms Button Examples

Learn Buttons in C# Windows Forms via simple examples

This tutorial will help you learn the following concepts:

1. How to create a Windows Form with a Button programmatically.
2. How to set Button properties like Text and Location programmatically.
3. How to handle button clicks in a button programmatically.

Example 1: Simple Button Example

Learn button in C# via these simple step by step exammples.

This example will comprise the following files:

• Button.cs

Step 1: Create Project

1. The first step is to create a C# Project.
2. Go to FILE-->New-->Project to create a new project.

Step 2: Write Code

Write Code as follows:

*(a). Button.cs

Create a file named Button.cs

Add using statements:

using System;
using System.Windows.Forms;

Create namespace:

namespace Examples {

Inherit from the Form class:

  class Form1 : Form {

Instantiate our Buttons as insance fields of this class:

    private Button button1 = new Button();
    private Button button2 = new Button();
    private Label label1 = new Label();
    private Label label2 = new Label();
    private int button1Clicked = 0;
    private int button2Clicked = 0;

Create our Main() method:

    public static void Main() {
      Application.EnableVisualStyles();
      Application.Run(new Form1());
    }

Declare the constructor:

    public Form1() {

Set the current form as the parent of our Button

      button1.Parent = this;

Set the Text property of our Button

      button1.Text = "button1";

Set the location of our button:

      button1.Location = new System.Drawing.Point(50, 50);

Handle click events of the button and subsequently update our label:

       button1.Click += delegate (object dender, EventArgs e) {
        label1.Text = string.Format("button1 clicked {0} times", ++button1Clicked);
      };

Create another button

      button2.Parent = this;
      button2.Text = "button2";
      button2.Location = new System.Drawing.Point(50, 100);
      button2.Size = new System.Drawing.Size(200, 75);
      button2.Click += delegate (object sender, EventArgs e) {
        label2.Text = string.Format("button2 clicked {0} times", ++button2Clicked);
      };

Here is the full code

using System;
using System.Windows.Forms;

namespace Examples {
  class Form1 : Form {
    private Button button1 = new Button();
    private Button button2 = new Button();
    private Label label1 = new Label();
    private Label label2 = new Label();
    private int button1Clicked = 0;
    private int button2Clicked = 0;
    public static void Main() {
      Application.EnableVisualStyles();
      Application.Run(new Form1());
    }

    public Form1() {
      button1.Parent = this;
      button1.Text = "button1";
      button1.Location = new System.Drawing.Point(50, 50);
       button1.Click += delegate (object dender, EventArgs e) {
        label1.Text = string.Format("button1 clicked {0} times", ++button1Clicked);
      };

      button2.Parent = this;
      button2.Text = "button2";
      button2.Location = new System.Drawing.Point(50, 100);
      button2.Size = new System.Drawing.Size(200, 75);
      button2.Click += delegate (object sender, EventArgs e) {
        label2.Text = string.Format("button2 clicked {0} times", ++button2Clicked);
      };
      label1.Parent = this;
      label1.Text = "button1 clicked 0 times";
      label1.Location = new System.Drawing.Point(50, 200);
      label1.Width = 200;

      label2.Parent = this;
      label2.Text = "button2 clicked 0 times";
      label2.Location = new System.Drawing.Point(50, 230);
      label2.Width = 200;
    }

  }
}

Example 2: C# Button Example

Simple step by step Button example in C#.

This tutorial will help you learn the following concepts:

1. How to create buttons programmatically in C# WinForms.
2. How to handle Button clicks using delegate

This example will comprise the following files:

• Button2.cs

Step 1: Create Project

1. The first step is to create a C# Project.
2. Go to FILE-->New-->Project to create a new project

Step 2: Write Code

Write Code as follows:

*(a). Button2.cs

Create a file named Button2.cs

Add the following namespace

namespace Examples {

Extend the System.Windows.Forms.Form:

  class Form1 : System.Windows.Forms.Form {

Define our Form1 constructor

```csharp
    public Form1() {

Onto the Controls property of our Form, instantiate our System.Windows.Forms.Button objects, set their properties and add them

      this.Controls.Add(new System.Windows.Forms.Button { Text = "button1", Location = new System.Drawing.Point(50, 50) });
      this.Controls.Add(new System.Windows.Forms.Button { Text = "button2", Location = new System.Drawing.Point(50, 100), Size = new System.Drawing.Size(200, 75) });
      this.Controls.Add(new System.Windows.Forms.Label { Text = "button1 clicked 0 times", Location = new System.Drawing.Point(50, 200), Size = new System.Drawing.Size(200, 20) });
      this.Controls.Add(new System.Windows.Forms.Label { Text = "button2 clicked 0 times", Location = new System.Drawing.Point(50, 230), Size = new System.Drawing.Size(200, 20) });
      this.Controls[0].Click += (sender, e) => this.Controls[2].Text = string.Format("button1 clicked {0} times", ++this.button1Clicked);
      this.Controls[1].Click += (sender, e) => this.Controls[3].Text = string.Format("button2 clicked {0} times", ++this.button2Clicked);
    }

Here is the full code

namespace Examples {
    //end
  class Form1 : System.Windows.Forms.Form {
        //end
        //Create the main method and inside it EnableVisualStyles and run the application:
    public static void Main() {
      System.Windows.Forms.Application.EnableVisualStyles();
      System.Windows.Forms.Application.Run(new Form1());
    }
        //end

    public Form1() {
            //end
      this.Controls.Add(new System.Windows.Forms.Button { Text = "button1", Location = new System.Drawing.Point(50, 50) });
      this.Controls.Add(new System.Windows.Forms.Button { Text = "button2", Location = new System.Drawing.Point(50, 100), Size = new System.Drawing.Size(200, 75) });
      this.Controls.Add(new System.Windows.Forms.Label { Text = "button1 clicked 0 times", Location = new System.Drawing.Point(50, 200), Size = new System.Drawing.Size(200, 20) });
      this.Controls.Add(new System.Windows.Forms.Label { Text = "button2 clicked 0 times", Location = new System.Drawing.Point(50, 230), Size = new System.Drawing.Size(200, 20) });
      this.Controls[0].Click += (sender, e) => this.Controls[2].Text = string.Format("button1 clicked {0} times", ++this.button1Clicked);
      this.Controls[1].Click += (sender, e) => this.Controls[3].Text = string.Format("button2 clicked {0} times", ++this.button2Clicked);
    }

    private int button1Clicked = 0, button2Clicked = 0;
  }
}
