Hi,

I am getting following error while uploading files. To reproduce the issue, select multiple files and make sure that one of the file is open.

Please help me in handling this issue.

Microsoft JScript runtime error: Unhandled Error in Silverlight Application [IO.IO_SharingViolation_File]

I could capture the error as below but not sure how to suppress the error using set_handled()

Hi Sanjivani,

Invoke the set_handled with a true parameter, like this:

args.set_handled(true);

Thank you. It seems it is stopping subsequent errors. But still left with one more problem. If I upload multiple files and lets say second file is in use, then second file shows red bullet and the files next to second file keep on blinking and never stops uploading.

Any way to make remaining files working?

Hello Sanjivani,

Hi, Has this issue been addressed?. If so, could you please let me know the version info?...I just downloaded the latest Trail version and I can repro this error...The Version# on the Telerik.Web.UI is 2013.1.220.35


Thanks,

Hello,

This used to happen in the Silverlight version. As of now, Silverlight is only supported under IE7/8/9.
Please check whether the problem still prominent.

All the best,

In my case it had to do with the IE-compatibility...

Event thought I was using IE 10, the response was always being rendered in IE7 compatibility mode. The locked multiple attachments using the RadAsyncUpload failed with the IO.IO_SharingViolation_File exception.

Adding the following to the web.config under <system.webServer>  resolved the issue...

        <httpProtocol>       
            <customHeaders>         
                <add name="X-UA-Compatible" value="IE=Edge"/>       
            </customHeaders>     
        </httpProtocol>

Hi Sashi,

Thank you for sharing your solution with the community.
