[Solved] When uploading multiple files, user cancelling file uploads does not always trigger OnComplete

[Sebastian S]

Hi,
We've noticed a problem that occurs irregularly when uploading multiple files (Chrome/Firefox). 
When the user cancels multiple uploads, the .OnComplete handler does not always get triggered
(sometimes it is triggered before the cancel).

Code is as below. Help!

Sebastian

@(Html.Telerik().Upload()
		.Name("files")
		.Multiple(true)
		.Async(async => async
			.Save("Save", "Job")
			.AutoUpload(true)
		)
		.ClientEvents(events => events
			.OnComplete("onUploadComplete")
			.OnError("onUploadError")
			.OnCancel("onUploadCancel")
			.OnSuccess("onUploadSuccess")
			)
)
<script type="text/javascript">

	function onUploadCancel(e) {
		console.log('upload cancel :' + e.files[0].name);
 
		//setTimeout('$(".t-upload-files").remove();', 1300);
	}
 
	function onUploadComplete(e) {
		console.log('upload complete');
		//$('.t-upload-files').remove();
		setTimeout('$(".t-upload-files").remove();', 1300);
	}
 
	function onUploadError(e) {
		console.log('upload error');
		console.dir(e);
	}
 
	function onUploadSuccess(e) {
		console.log('upload success: ' + e.files[0].name);
		console.dir(e);
	}

</script>

Hi Sebastian S,

I reproduced the case in which the OnComplete event never gets fired. It seems to occur when you cancel the last upload. We will try to fix this in one of the next official releases.
Could you share a little more information in which circumstances the OnComplete event gets fired before the OnCancel? Thanks in advance.

Can't really give you an exact example(It seems pretty random) - but it usually happens when uploading multiple files and a few files in the process of uploading get cancelled.
