    Hi Telerik,

    File filtering is not working in google chrome, but in IE it is ok.

    Telerik Version: 2012.3.1127.35
    Runtime Version: v2.0.50727

    <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1"  OnClientFileUploaded="OnFileUploaded"         OnClientFileUploadRemoved="OnClientValidationFailed"
                            OnClientFileDropped="OnClientValidationFailed" OnClientValidationFailed="OnClientValidationFailed" 
                            ManualUpload="false" MultipleFileSelection="Disabled" MaxFileInputsCount="1" MaxFileSize="5000000" width="220px">
            <telerik:FileFilter Description="Documents(pdf;tiff;tif)" Extensions="pdf,tiff,tif" />
        <Localization Select="Browse" />

    I'm filtering pdf and tiff documents only, but when I click Browse/Select in RadAsyncUpload it shows all the files in the directory when i use chrome.

    Please advice. Thanks!

    Hi Jay,

    RadAsyncUpload uses Upload Modules for different browsers. For Internet Explorer it uses Silverlight which allows to display the filter extensions in Open Dialog Window. For other modules that support rest of the browsers filter is working but it is not displayed in the Open Dialog Window as modules don't support it. Here is the help topic where this issue is explained.

    When will functional file filtering be available in the Telerik RadAsyncUploadcontrol? The HTML5 input type=file control provides this functionality without the use of silverlight or flash, which Telerik is rendering to the page. If I add the accepts property inline through a devloper tool, the filter works just fine. ​So I am unclear why Telerik does not support this, it only requires the addition of one property to the rendered input type=file html control
