event handler for form closing in c#

[john1a98]

Hi,

I am new to c#. I am writing code to event handler when windowsform is closed

My code:

private void CANToolFormClosing(object sender, CancelEventArgs e)
        {
            DialogResult dr = MessageBox.Show("Do you want to exit from the application?", "Are you Sure???", MessageBoxButtons.YesNo, MessageBoxIcon.Question);


            if (dr == DialogResult.No)
                e.Cancel = true;
        }

I do not understand why this code is not working.

Thanks in advance
John
