and you would notice that it is not showing the progress correctly.


I am having problems with IE9 with asyncupload with the progress but not in other versions / browsers

Hi Mohamed,

I tested http://demos.telerik.com/aspnet-ajax/progressarea/examples/asyncuploadintegration/defaultvb.aspx?product=asyncupload in IE9, but I was not able to reproduce an issue on this online example. Here you may find the result of my test.

Could you please explain in more details or record a sample video showing the exact issue you are facing?

Hi 

Please see attached image of ie9 browser doing the upload.

Also attached is the ie network capture file in xml -  http://wikisend.com/download/244162/recorded_ie.xml

For the IE9, I am using the vm image from https://www.modern.ie/en-us/virtualization-tools for IE9 on windows 7. I believe if you test on this VM, you will face same issue as me.

[Mohamed]

Just an update - I install chrome in the VM and the progress bar is showing update correctly

So no issues for chrome....but still having for IE9.

Hi Mohamed,

Thank you for the provided screenshot.

First let me clarify how the AsyncUpload works. In order to bring consistence between the older and modern browsers it uses Upload Modules. For IE8 and IE9 it uses Silverlight Module. To verify that right click on control if you see the Silverlight dialog then you using this module - http://screencast.com/t/UPA8IRrML3pU

In your case the progress you see on the ProgressArea is taken from the Silverlight. We just read and display it. Unfortunately it is not very precisely as this is a web uploading. Silverlight cannot predict the load of the server and the delay in the users connections. If this is the problem you face I would like to inform you that this is a limitation, which cannot be avoided. As far as I see on the attached image you highlighted the name of the file. Do you experience issues with that part of the progress? Does it show different name than the selected file? If so please let me know, so I can make further investigation.

I was just masking the filename ...it's returning the filename correctly.

However, have you checked from the xml file of the network, it keep returning 
var rawProgressData = {InProgress:false,ProgressCounters:false}; 

[Mohamed]

By the way, it is not using silverlight.

Checking the network it is using form post submit with polling requests which return the same data throughout.

Hello Mohamed,

Actually, the upload uses iframes to upload files (IFrame module) when neither Silverlight nor Flash is available. Consecutively,  we managed to reproduce a problem on our side where the polling to the sever didn't end with the file upload but continued afterwards returning default data.

In order to resolve the issue on your side please enable Flash or Silverlight while uploading files. On our side we will log the bug for fixing for the next release.
