Hi All!
First, Thanks very much. I also have another
problem. If in my page have 3 textboxes.. I want user
put "ONE" in first textbox, "TWO" in second textbox,
"THREE" in the third.. In the same time, for each
textbox, it will check immediately that it's valid
data, or not.. If it 's not, the user can't move to
the next text box.. How can I do it?
Thanks very very much in advance
Regs,
Moo

Hi Moo,
If textboxOne has not got valid content use textboxOne.focus at the end
of the validation routine to place the curser back in it. Since the
validation routine will be called again if the user moves the curser
(using the textboxOne onchange event) this will happen everytime, until
the data is valid.
If(notvalid)
textboxOne.focus
End If

YUou also can use the LostFocus() event of the text box. This will trigger
your validation routine when the focus is left from the text box. The
problem is that you can get the user in a LOOP if you constantly reset the
focus to the text box. Do your validation routine once, on lost focus, and
then at the time of submittal. This will keep data integrity, and also the
user wont get mad and leave your page.
