How to show warning when updating events?

[Boris]

Hello guys,

is it possible to display a warning on the scheduler when Update action is triggered? It happens often that users change the dates by mistake when using scheduler (they drag and drop or expand).

Thanks.

Hello Boris,

If Dragging and Dropping events and expanding them is not desired you can disable those features via the .Editable() configuration and setting the .Move(false) and .Resize(false):

.Editable(e=>e.Move(false).Resize(false))

If the functionality is required you can handle the MoveEnd and ResizeEnd events and prompt the user to confirm the change, for example you can implement the following handler for the MoveEnd event:

function scheduler_moveEnd(e) {
          var scheduler = e.sender;
          var task = e.event;
          var start = e.start;
          var end = e.end;
          e.preventDefault()
          kendo.confirm("Save changes").then(function(){
            var editedEvent = scheduler.dataSource.get(task.id);
            editedEvent.set("start",start);
            editedEvent.set("end",end);
          })
        }

Here is a dojo that demonstrates this in action.
