I have a file upload control that has been working fine until I made some unrelated (in theory) changes over the last couple of weeks and now the file upload doesn't work.
The OnClientUploadComplete is an client side event handler. And it must be bound to JavaScript function. Just add onto your page script element with this function:
So, you should have something as below in your js code:
<script type="text/javascript">
function UploadComplete() {
alert("File uploaded");
}
function UploadStart() {
alert("File uploaded");
}
You could refer to the tutorial below about how to use AjaxFileUpload:

ajaxToolkit:AjaxFileUpload Issues

Hi,
I have a file upload control that has been working fine until I made some unrelated (in theory) changes over the last couple of weeks and now the file upload doesn't work.

As a test, I created a new file upload:
But as soon as I apply client events, it doesn't render (see above):
I've compared the output and the two versions are identical, apart from the initialisation function that is automatically created:
// PREVIOUS BUILD (WORKING) ... <script type="text/javascript"> //<![CDATA[ Sys.Application.add_init(function() { $create(Sys.Extended.UI.AjaxFileUpload.Control, {"allowedFileTypes":"mp3","clearFileListAfterUpload":true,"clientStateField":$get("cphPageContent_ModalAudioUpload_AjaxFileUpload_ClientState"),"contextKey":"cphPageContent_ModalAudioUpload_AjaxFileUpload","maximumNumberOfFiles":1,"postBackUrl":"/my_page?id=12345","serverPollingSupport":true}, {"uploadComplete":UploadComplete,"uploadStart":UploadStart}, null, $get("cphPageContent_ModalAudioUpload_AjaxFileUpload")); }); //]]> </script> </form>// CURRENT BUILD (NOT WORKING) ... <script type="text/javascript"> //<![CDATA[ Sys.Application.add_init(function() { $create(Sys.Extended.UI.AjaxFileUpload.Control, {"allowedFileTypes":"mp3","clearFileListAfterUpload":true,"clientStateField":$get("cphPageContent_ModalAudioUpload_AjaxFileUpload_ClientState"),"contextKey":"{DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}","enabled":true,"maximumNumberOfFiles":1,"postBackUrl":"/my_page?id=12345","serverPollingSupport":true,"uploadHandlerPath":"/AjaxFileUploadHandler.axd"}, {"uploadComplete":UploadComplete,"uploadStart":UploadStart}, null, $get("cphPageContent_ModalAudioUpload_AjaxFileUpload")); }); //]]> </script> </form>Anyone know what's happened and how to fix?

Thanks Cathy, somehow I had deleted the UploadStart() function!
