Hi Mastermehdi,

I have tested your sample code(with the latest version of our control) and everything works fine on my side. Please review the following video. Also please clarify which version of our control are you using.

All the best,

I have same problem but only on one single machine. It works everywhere in all the browsers we've tested. But on one of the computers in IE asyncUpload.UploadedFiles[i].ContentType is null.

I'm using Telerik.Web.UI.dll version 2013.2.717.40

I understand that more information is required but I don't have any at the time being. Still working on it.

Peter,

Here is what I could get:

I have no idea how this happens. They've tried different files and it's always the same. It could be something with the client's browser.

Hi Sergey,

I have tested to upload a pdf file under IE10 and the returned content type is the correct one. Does the issue exists for the user under different browser? Do you use a custom handler?

I've tested it under different versions of IE and couldn't reproduce the error. Neither I get the error in other browsers.
No, I don't use a custom handler.

It happened for couple of other users. Here is some info about their systems:

UserAgent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.3; WOW64; Trident/7.0; .NET4.0E; .NET4.0C; .NET CLR 3.5.30729; .NET CLR 2.0.50727; .NET CLR 3.0.30729)

ctl00_cphMain_rupAttachments_ClientState: {'isEnabled':'true','uploadedFiles':[{"fileInfo":{"FileName":"Report.PDF","ContentType":null,"ContentLength":382599,"DateJson":"2014-04-22T17:42:50.565Z","Index":0},"metaData":"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"},{"fileInfo":{"FileName":"4096 INV.PDF","ContentType":null,"ContentLength":43464,"DateJson":"2014-04-22T17:40:22.599Z","Index":1},"metaData":"CS8S/Z0J/b2982DRxDin0BBslA7fI0cWMuWlPu4W3FmIgh1kJLpmV/tNKc1jkGTbCyPR/icMqGEpM5l9hu0iYcz282ymGmjo559eYix/JRw3sKDJhnU2GVsHvtrs96pxHqIxbHmewE7pynqtP29VjEVJ5GluSRMIKO6xxz6gU6Zrs5rGIwl6UQT6oWhevRTewudXF/UiGJnyd30kuscMcSD5DY1/hLxfT+PRooFgFeR6nJOgc07G5phCcmMJMLm+2Xc3ryGtnLIsTZ9qYkPKmOMTKl/GMXUWrPSwplUAASRpNjlfGmdLq8GwsuDwh3JbSFopBouo0cLKZvipJWahMJohBG2RDl6IMq/wALpRZtkjNjY02umeGj1AydGCJxF5cZps+h4E0HlT3XGkLp/oHSDxnurBg0H6QSN1p0yh/FMLpk3+dBRfWm9SGJ2C9p/JmQnoBvGywU+rdK4Q2KLRGpd+Sk7LcGfy9rSUQWZkMJu89thh1hIrhcbqQTKGWF3H"}]}

As you can see browser sends "ContentType":null. They've emailed me the files they tried to upload and I didn't have any problems uploading them myself. So the files aren't corrupted.

Here is how I define the control:

<telerik:RadAsyncUpload ID="rupAttachments" runat="server" ControlObjectsVisibility="RemoveButtons, AddButton"
                    ReadOnlyFileInputs="True" AllowedFileExtensions=".pdf,.xml" OnClientAdded="OnClientAddedHandler"
                    OnClientFileUploadRemoving="OnClientFileUploadRemoving" OnClientFileUploadRemoved="OnClientFileUploadRemoved"
                    TemporaryFileExpiration="01:00:00" OnClientValidationFailed="OnClientValidationFailed">
</telerik:RadAsyncUpload>

I don't know what other information can be helpful in this case. And I don't have access to the clients' machines to test it myself.
It's not a major issue for us as there is an easy workaround by checking that property for null. But there is definitely an issue with RadAsyncUpload control.

Hi Sergey,

It is really strange behavior. Probably it is related with some custom configuration of the IE. Until now, we haven't a report with similar problem. Please contact us if you reproduce the problem.

Hello,

We deployed and tested the sample scenario that you described with multiple files of different types, but at our end the behavior with the ContentType returning null was not reproduced. Could you provide more details whether the issue can be observed in all browsers or it is browser-specific s owe could be more helpful?
