Button 4- How to: Create a Non-Rectangular Button

How to: Create a Non-Rectangular Button
This example demonstrates how to create a button that is a different shape from the standard rectangular button. The code adds a button in the shape of a circle to the form and creates an event handler that displays a message when the circle is clicked.

public Form2()
{
//
// Required for Windows Form Designer support.
//
InitializeComponent();
// Initialize the user-defined button,
// including defining handler for Click message,
// location and size.
myButtonObject myButton = new myButtonObject();
EventHandler myHandler = new EventHandler(myButton_Click);
myButton.Click += myHandler;
myButton.Location = new System.Drawing.Point(20, 20);
myButton.Size = new System.Drawing.Size(101, 101);
this.Controls.Add(myButton);
}
public class myButtonObject : UserControl
{
// Draw the new button.
protected override void OnPaint(PaintEventArgs e)
{
Graphics graphics = e.Graphics;
Pen myPen = new Pen(Color.Black);
// Draw the button in the form of a circle
graphics.DrawEllipse(myPen, 0, 0, 100, 100);
myPen.Dispose();
}
}
// Handler for the click message.
void myButton_Click(Object sender, System.EventArgs e)
{
MessageBox.Show("Click");
}
