ListView undo drag and drop

[Peter]

In the attached below, I don't want an Empty to be dragged to another Empty.   But anything else is allowed.

Is there an undo event?

Thanks

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,
