Closing form taking user confirmation on buttton click event

Question

code to close a form on button click event and taking confirmation (Yes/No message box) from user before closing it?

You'll need to handle the form's FormClosing event (add the handler from the Properties Box). The code will be something like this: private void Form1_FormClosing(object sender FormClosingEventArgs e) { DialogResult dr = MessageBox.Show(Are you sure you want to close this form? Confirmation of Form Closure MessageBoxButtons.YesNo); if (dr == DialogResult.No) e.Cancel = true; }
