You could try to match for an extension, but there's no requirement for a file to have an extension.

There are probably dozens of way to format a phone number.

Your user interface should take care of the formatting problem by having a clear documentation on the format and/or split the phone into parts (area, exchange, number) and/or have an entry mask.

The following expression is pretty lenient on the format and should accept 999-999-9999, 9999999999, (999) 999-9999.

This will LEAVE the content of the tags within the string.

Ok so I've searched, found and reviewed/tested mutiple validation controls that all seem to not work for me when trying to limit only down to .jpg/. What I have right now, All I get is my message about only uploading jpg's. ANd i'm really only wanting client side validation. Hi Tim, I believe the reason this isn't working is that the File Upload control doesn't actually do the processing of uploading the file.

Consult the regular expression documentation or the regular expression solutions to common problems section of this page for examples. You can create range of characters using the hyphen character such as A-Z (A to Z).

If you need more examples or solutions, please contact me. Note that in character sets, special characters (., *, ) do not have any special meaning. This means match anything that is a single white space character OR anything that is not a white space character!

Make sure to be in global mode (g flag), case insensitive and to have the dot all option on.
