Button.DialogResult Property

public virtual DialogResult DialogResult { get; set; }

Implements

If the DialogResult for this property is set to anything other than None, and if the parent form was displayed through the ShowDialog method, clicking the button closes the parent form without your having to hook up any events. The form's DialogResult property is then set to the DialogResult of the button when the button is clicked.

For example, to create a "Yes/No/Cancel" dialog box, simply add three buttons and set their DialogResult properties to Yes, No, and Cancel.

The following code example creates a Button, sets its DialogResult property to OK, and adds it to a Form.

private void InitializeMyButton()
 {
    // Create and initialize a Button.
    Button button1 = new Button();

    // Set the button to return a value of OK when clicked.
    button1.DialogResult = DialogResult.OK;

    // Add the button to the form.
    Controls.Add(button1);
 }
