I noticed some were having issues with case sensitivity. You can modify the mode in the regular expression by adding some modifiers. To turn off case sensitivity use (?-i) and to turn on multiline use (?m). So the regular expression would be:
(?-i)(?m)^(?=.*?\d)(?=.*?[a-z])(?=.*?[A-Z])[a-zA-Z].{8,20}$
(I also added code to require a password to start with a character)

Simply do

and use single backslash(\), ie.

(do not change the .* position otherwise it won't work.)

It appears that the Javascript implimenation consistantly performs a "greedy match" and does not backtrack correctly to impose constrants on the positionally relivent portion of the pattern i.e anything not inside (?= ). As a workaround the last pattern supplied is suitable. However, it does not correctly enforce the maximum number of characters. (?=[\w$#_ ]{6,20}) will match between 6 and 20 characters anywhere in the string. Therefore, the strings length is only limited by resources. A simple correction can be made to enforce the string start and beginning in the first zero-width lookahead match (FYI "_" is included in all implimenations of \w that I am aware of):
"(?=^[\w$#]{6,20}$)(?=.*?\d)(?=.*?[A-Z])(?=.*?[a-z])^[\w$#]*$"
This pattern has been validated for both Clientsidejavascript and ServerSide .NET validation controls. Thanks to all who contributed to this thread. I was going in circles trying to figure out why my client side validation was not matching proper

Password must contain 6 characters and no more than 20,
at least one upper case letter (A-Z),
one lower case letter (a-z),
and one numeric character (0-9).
The other characters may be from the set A-Za-z0-9$#_\ plus blank.

Steven,
I was trying to use your example regex because I need to extend it to do the following:
The password should have 3 out of 4 character classes:
1. Uppercase letters
2. Lowercase letters
3. Numerics
4. Special characters [@#$%^&]
Any help that you can provide will be greatly appreciated.

Comment:
Using ClientTarget="downlevel" does force the page to handle expression on the server-side. However, other parts of the page look bad. Try setting the EnableClientScript attribute to false for the regular expression that is giving you problems. All other validators on the page will still use the client-side validation. It appears that the portion that causes these client-side errors are the "(?=.*" patterns.
