You need to check for the part after the " . " from right side of the filename.

If you have the file name in a string variable, you can use
[CODE=cpp]if(fileName.End sWith(".pdf"))[/CODE]

I have file path stored in a variable.But this code works in code file.I need to do it from client side (java Script).
I wrote a function and achive the result.
But i want another solution.

Gyanender,

U can use the below example as reference...

<asp:RegularExp ressionValidato r
id="RegularExpr essionValidator 1" runat="server"
ErrorMessage="O nly mp3, m3u or mpeg files are
allowed!" ValidationExpre ssion="^(([a-zA-
Z]:)|(\\{2}\w+)\$ ?)(\\(\w[\w
].*))+(.mp3|.MP3 |.mpeg|.MPEG|.m 3u|.M3U)$"
ControlToValida te="File1">
</asp:RegularExpr essionValidator >

As ur case is to check for .pdf extension, then just repalce +(.mp3|.MP3|.mp eg|.MPEG|.m3u|. M3U) with +(.pdf|.PDF)
