Hi,
You can take your regular expression as
[CODE=javascript]reg_exp = /^.+(\.(pdf))$/i[/CODE]
and match it with you file name.

Happy programming!

Hi ,
I gave the REV tag as:

<asp:RegularExp ressionValidato r ID="revInputfu " ValidationExpre ssion ="/^.+(\.(pdf))$/i" ControlToValida te ="fuFormTemplat e" display="Dynami c" Text ="$$" runat="server" ></asp:RegularExpr essionValidator >

File Path as:
"C:\Project\let ter\PDF\14_One Year DNR (Insured No Longer A Member) (7_93).pdf"
Its not working.
