Hi,

I have a situation where I need to move a RadAsyncUpload control in the DOM. After I move it the AllowedFileExtensions seems to be reset to allow all extensions. I have not been able to work out how to set the AllowedFileExtensions via javascript.

Here is the problem isolated in a simple example. Initially only jpg and wmv files can be selected. But once I click the bt_MoveDiv button and move the control in the DOM, all file types can be selected.

<body>

<form id="form1" runat="server">

<script language="javascript" type="text/javascript">

function buttonClick() {

var container = document.getElementById('container');

var ph = document.getElementById('holder');

ph.appendChild(container);

}

</script>

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<div id="container">

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="jpg,wmv">

</telerik:RadAsyncUpload>

<telerik:RadProgressArea ID="RadProgressArea1" runat="server">

</telerik:RadProgressArea>

<asp:Button ID="bt_Submit" runat="server" Text="Submit" onclick="bt_Submit_Click" />

</div>

<div id="holder">

</div>

<asp:Button ID="bt_MoveDiv" runat="server" Text="Move div" OnClientClick="buttonClick();return false;" />

</div>

</form>

</body>

I had similar problems some time ago with RadEditor being moved in the DOM. This problem was fixed with the onParentNodeChanged() function. Is there something similar I can do for RadAsyncUpload?

Thanks
Andrew

Hi Andrew Dixon,

A possible solution is to use the Flash module to upload files. You need to disable your Silverlight module. Please add the following code to your page:

<script language="javascript" type="text/javascript">

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

</script>

Another solution is to check the allowed file extensions client-side with the method get_allowedFileExtensions(). For more details refer to the help article.
