The Upload has two more of operation: synchronous and asynchronous. In sync mode the Upload must be placed in a form and the selected file is sent on form submission. In async mode the selected file is sent with a request to the server immediately upon selection or after confirmation through the Upload's UI. There is no need to use a form in this mode.
For more details on both modes of operation, refer to this documentation article: https://docs.telerik.com/kendo-ui/controls/editors/upload/modes
The following demo showcases the async upload functionality: https://demos.telerik.com/kendo-ui/upload/async
