You should check your ShowDialog(); calls return values in order to find out which button was actually pressed.

Something like that

......................................
// Show dlg as a modal dialog and determine if DialogResult = OK.
if (dlg.ShowDialog() == DialogResult.OK)
{
...............................
}
