ListView undo drag and drop

Hi Peter,

The Kendo UI Sortable widget exposes the End event. It can be prevented. What I can suggest is that you subscribe to this event and in case the value of the item is 0 or empty call the preventDefault() method.

.Events(ev=>ev.End("onEnd"))

function onEnd(e){
    if(condition){
        e.preventDefault();
     }
}

The item could be accessed via the e.item argument. More information could be found here:

In case further assistance is required, let me know.

Best regards,
