Prevent Kendo Scheduler events from inconsistent removal

[Nick]

Hi, 

We do have a kendo scheduler bound to a remote data source.

The "transport" configuration of this scheduler's data source is done using remote urls (for CRUD), and this works perfectly,

On the server side, we make a lot of checks. So if some requirements are missing, Create, Update or event Destroy operations wouldn't pass and user will be shown the meaningful error.

The problem we're facing now is like the following :

For the Destroy action, what kind of response should we send back (from the server)  to the scheduler component (in the browser on the client side )  to prevent removal of events in the UI?

We've tried :

• Sending back HTTP 500 status code
• Putting an error field in the response and linking it to the schema.error configuration

But events are still removed from the UI, nevertheless the error event is fired. We even use this event to notify errors to end used.

Thank you.

Hi Nick,

I am afraid we do not provide a mechanism that would prevent the removing of the task in Scheduler in the described scenario. However, what you could try is to call the dataSource read method after the error is returned from the server. 

- https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/read

Using the read method will send a new request to the 'read' endpoint. Thus, the Scheduler will be populated with all the tasks that are still present in the data.

I hope this helps.
