MessageBoxButtons Enumeration

.NET Framework 4.5

Specifies constants defining which buttons to display on a MessageBox.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

public enum MessageBoxButtons

	Member name	Description
	OK	The message box contains an OK button.
	OKCancel	The message box contains OK and Cancel buttons.
	AbortRetryIgnore	The message box contains Abort, Retry, and Ignore buttons.
	YesNoCancel	The message box contains Yes, No, and Cancel buttons.
	YesNo	The message box contains Yes and No buttons.
	RetryCancel	The message box contains Retry and Cancel buttons.

This enumeration is used by the MessageBox class.

The following code example shows how to use a MessageBox to give the user an opportunity to prevent a form from closing. This example requires that the method is called from the FormClosing event of the form.

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    const string message =
        "Are you sure that you would like to close the form?";
    const string caption = "Form Closing";
    var result = MessageBox.Show(message, caption,
                                 MessageBoxButtons.YesNo,
                                 MessageBoxIcon.Question);

    // If the no button was pressed ... 
    if (result == DialogResult.No)
    {
        // cancel the closure of the form.
        e.Cancel = true;
    }
}
