    Scheduler

    SignalR Service

    Documentation

    This demo shows how two users can edit data in the Scheduler simultaneously. A SignalR service is used to broadcast push notifications.

    Each Scheduler has an individual store to emulate the situation when Schedulers are being edited on two different clients. Changes made in one Scheduler are repeated in the other and persist until the browser session has expired.
