Context menu in Angular Schedule component

17 Jan 202316 minutes to read

You can display context menu on work cells and appointments of Scheduler by making use of the ContextMenu control manually from the application end. In the following code example, context menu control is being added from sample end and set its target as Scheduler.

On Scheduler cells, you can display the menu items such as New Event, New Recurring Event and Today option. For appointments, you can display its related options such as Edit Event and Delete Event. The default event window can be opened for appointment creation and editing using the openEditor method of Scheduler.

The deletion of appointments can be done by using the deleteEvent public method. Also, the selectedDate property can be used to navigate between different dates.

You can also display custom menu options on Scheduler cells and appointments. Context menu will open on tap-hold in responsive mode.
