Hi!
I've a form and I've 6 textbox.
If i send the form with 5 textbox written, i've an oblligatory error.
How can i manage the error??

:D

If I understood...
If you want to prevent the form's submitting if any of the textboxes is empty you can write some JavaScript code, and on the server side you will not receive an error caused by empty textbox.

HTH.
