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'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.
@mehdi You need to update in order to get fix. It is not possible to workaround the issue.
@ Let me know if you have more information on the case.

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.
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?

No, I don't use a custom handler.

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.
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.

Hi Peter,
Seems like the problem still exists,
Telerik web.ui.dll = Version 2015.1.225.45
USER AGENT: Browser (IE 11.0 on a Personal computer running Windows 8.1)

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?
