Hi Mikiya,

RadAsyncUpload utilizes four different modules for file uploading – Iframe, Flash, Silverlight and File Api. The module with highest priority is File Api. If the browser does not support File Api that module is automatically changed to Silverlight. If there is no Silverlight installed on the client machine, RadAsyncUpload will utilize the Flash module. If neither Flash nor Silverlight is installed – the IFrame module takes place and this is the order of selecting upload modules.

In the case of Internet Explorer, File Api Upload module is not suppoerted in any of its version and hence IE by default select the Silverlight upload module which has the next higher priority. Also note that there is an exception in IE9 that RadAsyncUpload implements only IFrame and Silverlight Upload modules in IE9. (Flash module can be applied in IE10 as well as IE versions prior to IE9.)

Thanks,
Shinu.

Hi Mikiya,

According to this Telerik help documentation on browser support for different Upload Modules, IE is supporting only Silverlight, Flash and IFrame. I have tested the same scenario in IE10 and IE9 and found that IE9 loads the Silverlight module by default but IE10 loads FileApi.

Suppose you want to know which upload module is used, you can try the following JavaScript.

JavaScript:

<script type="text/javascript">

function OnClientFileUploaded(sender, args) {

//returns the current upload module name

alert(sender.get_loadedModuleName());

}

</script>

If you want IE10 to use Silverlight module to upload files, you can disable the FileApi with the help of the following JavaScript.

JavaScript:

<script type="text/javascript">

Telerik.Web.UI.RadAsyncUpload.Modules.FileApi.isAvailable = function () { return false; }

</script>

Thanks,
Shinu.
