Kendo Upload control is completed

I am using the Kendo Upload control in a form and didn't want the form to be submit if the upload is still in process. I dont see any event I can use to let me know all files have been uploaded.

You can see a list of all events for the Kendo UI Upload here.

Among them you'll find the following events:

• progress - provides you with the list of selected files and the percentage of the upload progress
• success - Fires when the upload has finished (can be used only in async mode)
