RadAsyncUpload : Showing all the files

[Vimal]

Hi,

We are using  “RadAsyncUpload” to upload the files. We are restricted files selection types by specifying AllowedFileExtensions=".zip,.rar".
Its working as expected but  when we try to open the file selection dialog it list all the files in XP Operating system  (IE8) .

Controls Version details.
Telerik.Web.UI
FileVersion:2011.1.519.40
ProductVersion:2001.1.519.40

Code:
 <telerik:RadAsyncUpload ID="PatchFileUploadControl" runat="server" MaxFileInputsCount="1"
   OnClientFileSelected="FileSelected" OnClientFilesUploaded="FileUploaded" AllowedFileExtensions=".zip,.rar">
</telerik:RadAsyncUpload>

Please let  us know any changes to be done.

Hi Vimal,

The file filtering is available with Silverlight and Flash module only. Note that when RadAsyncUpload is utilizing its IFrame module (when neither Flash nor Silverlight is installed) no filtering capabilities are available. This is because browsers don’t provide native file filtering support. Please check the upload module used in the appilcation and try to disble the FileApi and IFrame module as follows.

JavaScript:

<script type="text/javascript">
    Telerik.Web.UI.RadAsyncUpload.Modules.FileApi.isAvailable = function () { return false; };
    Telerik.Web.UI.RadAsyncUpload.Modules.IFrame.isAvailable = function () { return false; };
</script>

Thanks,
Princy.
