    script type="text/javascript">



    function OnClientFileSelectedHandler(sender, eventArgs)







    var input = eventArgs.get_fileInputField();



    //check the extension



    if (sender.isExtensionValid(input.value))




    var img = document.getElementById('<%= imgAttach.ClientID %>');



    if (img)

    The limitation of above code is, it will work correctly on IE browser only, since in Firefox the input.value returns the filename instead of the full path to the file. For security reasons the code will work only on localhost, to make it work remotely you need to add the site to the Trusted Sites.

    Please check the Limitations part of this help article.



    Also go through the following forum link which discusses a similar scenario.
