    Button to select files for uploading unavailable in IE

    The button to select files for uploading is not always working Internet Eplorer. It looks enabled, but clicking on it does nothing. It does not bring up the file selection dialog.
    Other browsers don't have this issue. It is IE only.
     
    I'm using Internet Explorer 9 under Windows Vista.
     
    I see the same problem on your demo page at eg. http://ajaxuploader.com/Demo/select-multiple-files-upload.aspx 
     
    What can we do to solve this?

    Regards, Marja

    Re: Button to select files for uploading unavailable in IE

    Hi MarjaR,
     
    What version silverlight/flash plug-in you are using with your ie browser?
     
    Some time load the plug-in will take a few seconds. You just need to wait for the plug-in load complete.
     
    Regards,

    Re: Button to select files for uploading unavailable in IE

    Silverlight version 5.0.61118.0
    Shockwave Flash version 11.1.102.62
     
    Waiting a few seconds does not help. The button just won't work at all, no matter how long I wait.

    Re: Button to select files for uploading unavailable in IE

    Hi MarjaR,
     
    This issue should cause by your silverlight 5.
     
    Please download the latest version here http://ajaxuploader.com/download/Ajax-Uploader.zip and try again. It should work for you.

    Re: Button to select files for uploading unavailable in IE

    I tried the new DLL but it still doesn't work in Internet Explorer.
    The button to bring up the file selection dialog is black (enabled), then gray (disabled) and then black (enabled) again. But clicking on it does absolutely nothing.
     
    I have the latest version of the Silverlight plugin. So what else should I do to get this working?

    Re: Button to select files for uploading unavailable in IE

    Hi MarjaR,
     
    Please try on demo http://www.ajaxuploader.com/Demo/select-multiple-files-upload.aspx with your ie browser. Does it work for you?
     
    What I mean is the problem causes by your silverlight 5. I suggest you use silverlight 4. If you must use silverlight 5, please refer to the info below
     
    -------------------------------------------------- 
    It is the microsoft silverlight plug-in bug, silverlight 5 must use with Silverlight 5 Tools for Visual Studio .you can download the tools at http://www.silverlight.net/getting-started, it will fix the problem.
    Silverlight will not automatic updates to 5.0,If your client manually update to 5.0, then please let him instal the Silverlight 5 Tools too.
    --------------------------------------------------

    Re: Button to select files for uploading unavailable in IE

    The demo at http://www.ajaxuploader.com/Demo/select-multiple-files-upload.aspx doesn't work for me, regretfully.
    I will try downgrading Silverlight to version 4 and see if that changes anything.

    Re: Button to select files for uploading unavailable in IE

    I can' t find how to downgrade Silverlight to a lower version. It seems only version 5 (the one I already had) is available for download.
     
    So I tried setting UploadType="Flash" explicitly on the CuteWebUI:Uploader, to bypass Silverlight alltogether, but then I run into an error in the Ajax Uploader component:
    "Line: 1  Error: Unable to get value of the property 'length': object is null or undefined" 
     
    I get this same error in IE (without the Silverlight plugin being installed) on your demo page at http://ajaxuploader.com/Demo/select-multiple-files-upload.aspx 
    The upload itself succeeds, but the error is annoying.

    I can't ask my clients to install the Silverlight 5 tools. My clients are organisations and I don't know all the individual users.
    Asking them all to downgrade their Silverlight plugin (if at all possible) is simply not an option, nor is asking them all the install any additional tools.
     
    It should work out-of-the-box.

    Re: Button to select files for uploading unavailable in IE

    Hi MarjaR,
     
    The silverlight plug-in will not update to version 5 automatically.
     
    You can disable the silverlight upload mode by the code above, then it will not be the problem any more. 
     
       protected override void OnLoad(EventArgs e)
        {
            uploader1.SetAdvancedOption(UploaderAdvancedOption.NoSilverlight, "true");
            base.OnLoad(e);
        }

    Re: Button to select files for uploading unavailable in IE

    Like I wrote before, bypassing the Silverlight plugin (and thus using Flash instead) results in a JavaScript error in Internet Explorer:
    "Microsoft JScript runtime error: Unable to get value of the property 'length': object is null or undefined".

    Re: Button to select files for uploading unavailable in IE

    Test results in IE9 (with latest Silverlight plugin installed):

    1. Auto: does NOT work
    2. IFrame: works fine
    3. Flash: file gets uploaded, but I get a JavaScript error (afterwards?)
    4. Silverlight: does NOT work

    Re: Button to select files for uploading unavailable in IE

    Hi MarjaR,
     
    Do you mind disable your Anti-virus software and firewall to try again? By the way, reset the security settings of IE browser too.
     
    It works very well for me

    Re: Button to select files for uploading unavailable in IE

    Hi.
    I'm also experiencing this same issue with IE when I've deployed the web application to the web server. The weird think is that it's running ok in my development machine, and it also works fine in both machines, the development one and the server, with Opera, Firefox and Safari, but accessing using IE to the application deployed in the web server, the button simply doesn't fire the files selection dialog.
     
    I've downloaded the version from http://www.cutesoft.net/downloads/folders/44395/download.aspx so it seems that here isn't the solution. I've written an example that you can run in my web server with this url: http://peritaciones.tandemcr.com/pruajaxuploader/default.aspx. And below you can find the code.
     
    Thank you in advance
