Add an event handler to the FormClosing event:

private void MainPage_FormClosing(object sender, FormClosingEventArgs e)
{
   DialogResult dr = MessageBox.Show("Do you really wish to close?", "Closing...", MessageBoxButtons.YesNo);
   if (dr == DialogResult.No )
   {//don't close
      e.Cancel = true;
   }
}
