Hi,
I am sorry , it should be (Postback not PostBack):
<script>
function CuteWebUI_AjaxUploader_OnPostback()
{
alert("The file is uploaded , there will be a server error soon.");
}
</script>
I think that is server side error , and maybe that is caused by the new version of MSAJAX.
We will also test it .
Regards,
Terry
