The mgt-agenda web component represents events in a user or group calendar. By default, the calendar displays the current signed in user events for the current day. The component can also use any endpoint that returns events from Microsoft Graph.

Example

The following example shows the signed-in user's calendar events displayed using the mgt-agenda component. You can use the code editor to see how properties change the behavior of the component.

HTML
React

Open this example in mgt.dev.

Properties

By default, the mgt-agenda component fetches events from the /me/calendarview endpoint and displays events for the current day. There are several properties you can use to change this behavior.

Attribute	Property	Description
date	date	A string that represents the start date of the events to fetch from Microsoft Graph. The value should be in a format that is suitable for the Date constructor. This value has no effect if the `event-query` attribute is set.
days	days	The number of days to fetch from Microsoft Graph. The default is 3. This value has no effect if `event-query` attribute is set.
show-max	showMax	A number to indicate the maximum number of events to show. The default value isn't set (no maximum).
group-id	groupId	A string ID for a group calendar to use instead of the current signed in user's calendar.
event-query	eventQuery	A string that represents an alternative query to be used when fetching events from Microsoft Graph. Optionally, add the delegated scope at the end of the string by delimiting it with `\|` (`/groups/GROUP-ID-GUID/calendar/calendarView \| group.read.all`).
events	events	An array of events to get or set the list of events rendered by the component. Use this property to access the events loaded by the component. Set this value to load your own events. The `date`, `days`, or `event-query` attributes have no effect if set by the developer.
group-by-day	groupByDay	A Boolean value to group events by day. By default, events aren't grouped.
preferred-timezone	preferredTimezone	Name of the IANA time zone to use when displaying events retrieved from Microsoft Graph; for example, `America/Los_Angeles`. For a list of IANA time zones, see List of tz database time zones. By default, events render using the current time zone settings of the device.

The following example changes the behavior of the component to fetch data for a specific date and up to three days.

<mgt-agenda group-by-day date="May 7, 2019" days="3"></mgt-agenda>

The following example changes the behavior of the component to fetch data from a specific query.

<mgt-agenda event-query="/me/events?orderby=start/dateTime"></mgt-agenda>

Methods

Method	Description
reload()	Call the method to reload the component with potential new data based on its properties.

Templates

The mgt-agenda component supports several templates that allow you to replace certain parts of the component. To specify a template, include a <template> element inside of a component and set the data-type to one of the following values:

Data type	Data context	Description
`default`	`events`: list of event objects	The default template replaces the entire component with your own.
`event`	`event`: event object	The template used to render each event.
`event-other`	`event`: event object	The template used to render other content for each event.
`header`	`header`: string	The template used to render the header for each day.
`loading`	No data context is passed	The template used when data is loading.
`no-data`	No data context is passed	The template used when no events are available.

The following examples illustrate how to use the event template:

<mgt-agenda>
  <template data-type="event">
    <button class="eventButton">
      <div class="event-subject">{{ event.subject }}</div>
      <div data-for="attendee in event.attendees">
        <mgt-person
          person-query="{{ attendee.emailAddress.name }}"
          view="twolines"
        >
        </mgt-person>
      </div>
    </button>
  </template>
  <template data-type="no-data"> There are no events found! </template>
</mgt-agenda>

The component allows you to specify a different Microsoft Graph query to call (such as /groups/{id}/calendar/calendarView). In this case, append the permission to the end of the string, delimited by |.
