I'm not sure I'm interpreting you correctly, but:

1. To detect when the textbox has lost focus, use the TextBox.LostFocus
event. See its MSDN entry for more info. See here for a sample of some C#
code using it:

2. To update the label, simply modify the Text property of the label. You
can get the values in the textboxes using the TextBox.Text property. You may
also want to consider using a read-only textbox instead of a label, which
allows copying to the clipboard.

I hope this helps - please write back if I misunderstood your question or
you need more help.
