Hi Terry
Tested a bit more and I can confirm that the OnFileValidating event is the one firing.
However in my case I DONT have a OnFileValidating event and so don't want that postback to happen.
I can see that CuteWebUI_AjaxUploader_OnSelect() gets called but returning false stops the entire select process and return will then just let it continue and then calls the OnFileValidating event.
Is there any way we can stop the OnFileValidating postback/event happening?
