Client-Side Update

Call update() on the client side to update the Scheduler after changing the properties.

For a server-side assisted update, please use CommandCallBack (ASP.NET WebForms, ASP.NET MVC, Java versions).

Changing a Date (Example)

dps.startDate = "2025-05-01";
dps.update();

Remember to have the events preloaded or to load them manually using events.add().

API: update.

The examples switch to December and clear the old event collection in one update() call. In an application, load and supply events for the selected month.

The framework examples use DayPilot Pro. For installation, see the Angular, React or Vue Scheduler guide.

Angular

The template's (click) binding invokes a component method, which calls update() on the control obtained through @ViewChild.

import {Component, ViewChild} from "@angular/core";
import {DayPilot, DayPilotModule, DayPilotSchedulerComponent} from "daypilot-pro-angular";

@Component({
  selector: "app-scheduler-example",
  standalone: true,
  imports: [DayPilotModule],
  template: `
    <button (click)="action0()">Show December</button>
    <daypilot-scheduler [config]="config" #scheduler></daypilot-scheduler>
  `
})
export class SchedulerExampleComponent {
  @ViewChild("scheduler") scheduler!: DayPilotSchedulerComponent;
  config: DayPilot.SchedulerConfig = {
    startDate: "2026-11-01",
    days: 30,
    scale: "Day",
    timeHeaders: [{groupBy: "Month"}, {groupBy: "Day", format: "d"}],
    resources: [{id: "A", name: "Room A"}, {id: "B", name: "Room B"}],
    events: [{id: 1, text: "Planning", resource: "A", start: "2026-11-03", end: "2026-11-06"}, {id: 2, text: "Delivery", resource: "B", start: "2026-11-08", end: "2026-11-11"}]
  };
  async action0() {
    const dp = this.scheduler.control;
    dp.update({startDate: "2026-12-01", days: 31, events: []});
  }
}

React

Store the control supplied by controlRef in a ref so the navigation button can call scheduler.current.update().

import React, {useRef} from "react";
import {DayPilot, DayPilotScheduler} from "daypilot-pro-react";

export default function SchedulerExample() {
  const scheduler = useRef(null);
  async function action0() {
    const dp = scheduler.current;
    dp.update({startDate: "2026-12-01", days: 31, events: []});
  }
  return <div>
    <button onClick={action0}>Show December</button>
    <DayPilotScheduler
      controlRef={control => { scheduler.current = control; }}
      startDate={"2026-11-01"}
      days={30}
      scale={"Day"}
      timeHeaders={[{groupBy: "Month"}, {groupBy: "Day", format: "d"}]}
      resources={[{id: "A", name: "Room A"}, {id: "B", name: "Room B"}]}
      events={[{id: 1, text: "Planning", resource: "A", start: "2026-11-03", end: "2026-11-06"}, {id: 2, text: "Delivery", resource: "B", start: "2026-11-08", end: "2026-11-11"}]}
    />
  </div>;
}

Vue

The button uses @click to invoke the script function. The component ref exposes the API through scheduler.value.control.

<script setup>
import {ref} from "vue";
import {DayPilot, DayPilotScheduler} from "daypilot-pro-vue";

const scheduler = ref(null);
const startDate = "2026-11-01";
const days = 30;
const scale = "Day";
const timeHeaders = [{groupBy: "Month"}, {groupBy: "Day", format: "d"}];
const resources = [{id: "A", name: "Room A"}, {id: "B", name: "Room B"}];
const events = [{id: 1, text: "Planning", resource: "A", start: "2026-11-03", end: "2026-11-06"}, {id: 2, text: "Delivery", resource: "B", start: "2026-11-08", end: "2026-11-11"}];
async function action0() {
  const dp = scheduler.value.control;
  dp.update({startDate: "2026-12-01", days: 31, events: []});
}
</script>
