RadAsyncUpload and CustomValidator

[Mark]

I am trying to get the CustomValidator to work with the RadAsyncUpload, but not having any luck.

I have tried the example from here http://www.telerik.com/community/forums/aspnet-ajax/async-upload/required-validator-and-radasyncupload.aspx but the javascript never fires. What links the 2 controls togther? Normally I would set the ControlToValidate property of the CustomValidator, but that also does not work.

I have simplified the example (Should always fail validataion), but still no luck

   <script type="text/javascript">
      function validateUpload(sender, args) {
            args.IsValid = false;
        }
   </script>

 <div>
     <tel:RadAsyncUpload ID="RadAsyncUpload1" runat="server" MultipleFileSelection="Automatic" />
      <asp:CustomValidator runat="server" ID="CustomValidator" ClientValidationFunction="validateUpload" ErrorMessage="Select at least a single file" />
</div>

Bit of an update..

If I add a textbox onto the page with validation, the RadSyncUpload validation will trigger when the textbox is updated and its seperate validation is triggered

Fixed, I just call Page_ClientValidate('MyGroup') on FileUploaded
