I am using the Regular Expressions given below to validate files to be uploaded using FileUpload control
Above regular expression are working fine in Internet explorer but not working in Firefox 3.0.3...
Let me know if you have any expression which works fine in both the browsers ... and any reason u know .. Why it is not working in Firefox

If you are using that client-side, Firefox 3 probably has restrictions about accessing the FileUpload control client-side (which is the way it is supposed to be). The only sure way is to do the validation server-side.

If you look at the value of the file input control in Firefox closely you will see thta it only shows the file name and not a full path. If your reg exp taking that into account?

Try this expression instead of above (.*\.([gG][iI][fF]|[jJ][pP][gG]|[jJ][pP][eE][gG]|[bB][mM][pP])$)
I have tested in ie and mozilla as well working fine.

How exactly did you write the expression to make it work in firefox?
I wrote it like this and it still only works in IE and not firefox:
In firefox, it gives the error messgae but it still uploads non validated files to the server.
Can you show me exactly what you wrote for your expression and does this really work in firefox?

Just Copy and Paste this expression:

I don't know what I'm missing or entering wrong but it still doesn't do client side validation
in firefox. In IE it gives the error message and does not upload a non validated file.
In firefox it gives the error message but still uploads the non validated file to the server.
Here's what I entered:
<asp:RegularExpressionValidator ID="valUploadFile" runat="server"
ErrorMessage="must be a jpg, bmp. or gif file">*</asp:RegularExpressionValidator>
Is it possible that using asp.net 1.1 is causing the expression not to work?

Update: It's working now
My web application is in asp.net 1.1.
I requested the web hosting company to switch the server to run asp.net 2.0(the hosting company runs both 1.1 & 2.0)
Now the expression is working perfectly in firefox, IE, and Opera. I haven't checked any other browsers.

None of the expressions I tried in Firefox worked until I put the expression in (), then they all worked in both IE and Firefox.
[a-zA-Z\\].*(.pdf|.PDF)$ -- does not work in Firefox
