hi i'm new to .net field, i'm developing one application using ASP.NET
and C#.NET in that i get one problem that is how to validate user
entered date and time formate, for this problem wheather i have to use
RegularExpressi onValidator or any other Code, Give the response soon
i'm waiting for reply
I'm sure there are good reasons for doing this client side, but I've never
found one.
Data entry validation always needs to be done server-side when the user
submits the form: so why not just settle for that and do the validation
server side? You're doing a postback anyway, so there's no extra time taken
worth talking about.
I know that some people like to do validation as the data is entered, but I
don't really like that - as a user or as a designer: but I know opinions
vary. However, good practice determines that all the data is checked
server-side on submit anyway, so checking client-side is just doing the job
twice IMHO.
[In case anyone asks, the reason that data entry has to be checked server
side anyway is because you cannot be certain that the data was submitted
from the form exactly as you wrote it. People can turn off scripting; they
can save the page and modify it. All sorts of nefarious stuff can go on
between the server and client]
I'm tempted to sign off as Paranoid Peter, but I'll just make do with my
usual

Not true at all...
E.g. if you are writing a subscription site where users need to register,
and one of the criteria for registration is that registrants needs to be at
least 18 years old, then a simple client-side validation is perfectly fine -
there's no need for a round trip just to do that...
Or for checking that a date value is greater or less than another date value
e.g. today's date...
Or, even more importantly, to validate that mandatory fields actually do
contain a value...

I would have to agree with Peter on this one. For the reason that the
submittal of the form may be from a source that has script disabled, or
posted from another screen, or something similar....the client-validation
would never run, yet the postback would...or maybe the postback wouldn't
with script turned off....hmm...I' ll check it out.

Glad I double-checked. A form submittal is caused (usually) by a "submit"
input button and not through script, unless you are using a control that has
the AutoPostBack set to True or a LinkButton (or similar) control, which
then uses script and will not perform a postback if script is disabled on
the client...

Use the RegEx-validator, e.g.:
<asp:RegularExp ressionValidato r ID="myRegExVali dator" runat="server"
ControlToValida te="myBtn" ErrorMessage="W rong input, you need to write
a date in format dd/mm/yyyy" ValidationExpre ssion="^\d{1,2} \/\d{1,2}\/
\d{4}$" ></asp:RegularExpr essionValidator >
You can find examples of different date and time expressions here: http://regexlib.com/(A(eJE4ziet-S-qk...4&categoryId=5

or should I be binding, somehow, separately in the vb code? Please view my
