    Hi,

    We have upgraded our Telerik Version to 2013 Q2 (2013.2.611.40) and since then the RadAsyncUpload control does not work in IE9. When i select a file to upload it straight away rejects the file and shows me a red light. We use a custom asynhandler that uploads the file.

    The same file works fine in Firefox & Chrome. 

    Our markup looks as below 
    <telerik:RadAsyncUpload runat="server" id="fileUpload"  Width="100%"
                                HttpHandlerUrl="~/CustomAsyncHandler.ashx"
                                DisablePlugins="True" DisableChunkUpload="True"
                                EnableInlineProgress="true"
                                MultipleFileSelection="Automatic"
                                AllowedFileExtensions="xls,csv,txt,xlsx"                             
                                OnClientValidationFailed="onFileValidationFailed"
                                />


    Regards

    Hi,

    We are also facing the same issue. Infact it does not work in any versions of IE.
    Only a single file can be upload.
    We are using the following version of  2013.1.417.35

    Thanks in advance!

    Hi Mangleeswaran,

     
    I have tested the described scenario and it worked properly at my side and on our on-line demo here. I am attaching my test web page.

    You can also refer to this help topic where is described when the multifileselection is possible with RadAsuncUpload.

    Hope this will be helpful.

    Hi Plamen,

    Thanks for the quick reply.

    As I mentioned in my previous post the issue happenig only in Internet explorer browser.
    Even if you see in the help link provided by you is  using mozilla browser.

    Please do the needful.

    Regards

    Hi,

    We have finally resolved the issue and now know as to why this happens. We are using a custom async handler that returns the result object of type IAsyncUploadResult which has a string property that contains encoded XML. Even if we encode the XML it doesn't work in IE9 but works in other browsers. 

    We have now removed this property of the result object from having an encoded XML and everything is working fine now.

    Regards
    Rajesh
