regex problem - 2.0 beta 2

[Guest]

Here is an interesting one. Running asp.net 2.0 beta 2. I have a regular
expression used in a regex validator that works on the client side in
Firefox but not in IE. Any ideas? IE always reports the field is invalid.
The expression is:


^(?!\d)(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\W_]).{8,25}$

If I enter "Test_Field1" Firefox considers it valid on client side, IE
doesnt. Server side considers it valid too because when I submit the form in
Firefox I am presuming it is checked on server-side too?

TIA!

Hi Param,

Welcome to ASPNET newsgroup.
As for the regular expression validation problem you mentioned, does it
also occur when using 1.1 validator? Also, based on my understanding, it is
likely the outputed regular expression is somewhat changed(escaped or....).
Have you compare the html source in the client browsers to see whether
there're any difference?

IE:

ctl00_sitepagecontent_regex_password.validationexpression =
"^(?!\\d)(?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\\W_]).{8,25}$";

FIREFOX:
ctl00_sitepagecontent_regex_password.validationexpression =
"^(?!\\d)(?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\\W_]).{8,25}$";Looks the same
to me. Any ideas?

Thanks for your followup Param,

I've also performed some tests on my local environment based on the regex
you provided. I'd have to admit that this is
a exiting problem of the regular expression support of the IE browser. Even
we direct use some simple script to validate it as below:

function test() {
var re = new
RegExp("^(?!\\d)(?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\\W_]).{8,25}$");
var m = re.exec("Test_Field1");
if (m == null) {
alert("No match");
} else {
var s = "Match at position " + m.index + ":\n";
for (i = 0; i < m.length; i++) {
s = s + m + "\n";
}
alert(s);
}

}

Also, currently I think the problem will still remain in the IE and we need
to workaround it through some other means such as using serverside
validation. Sorry for the inconvience it brings you.
