Syncfusion Aspnetcore Scheduler

Implementing ASP.NET Core Scheduler

The Syncfusion ASP.NET Core Scheduler is a comprehensive component for managing appointments, events, and schedules. It provides rich functionality for creating calendar-based applications with support for multiple views, resources, recurring events, and extensive customization options.

When to Use This Skill

• Appointment Management: Creating, editing, and deleting calendar appointments
• Multi-User Scheduling: Implementing resource scheduling for multiple users or resources
• Calendar Views: Displaying events in day, week, month, timeline, or agenda formats
• Recurring Events: Managing repeating appointments with complex recurrence rules
• Data Integration: Binding local or remote data sources to the Scheduler
• Custom Templates: Customizing event appearance and templates
• Working Hours: Configuring business hours, working days, and timezones
• Event Operations: Drag-and-drop rescheduling, resizing, and inline editing

Quick Start Example

<!-- _Layout.cshtml -->
<head>
    <!-- refer syncfusion theme -->
    <!-- refer syncfusion script -->
</head>
<body>
    <!-- Scheduler will render here -->
    <ejs-scripts></ejs-scripts>
</body>

<!-- Index.cshtml -->
@addTagHelper *, Syncfusion.EJ2

<ejs-schedule id="schedule" width="100%" height="550" selectedDate="new DateTime(2024, 3, 28)" currentView="Week">
    <e-schedule-eventsettings dataSource="ViewBag.datasource"></e-schedule-eventsettings>
</ejs-schedule>

// Controller
public class HomeController : Controller
{
    public IActionResult Index()
    {
        ViewBag.datasource = new List<AppointmentData>
        {
            new AppointmentData { 
                Id = 1, 
                Subject = "Meeting", 
                StartTime = new DateTime(2024, 3, 28, 9, 0, 0),
                EndTime = new DateTime(2024, 3, 28, 10, 0, 0)
            }
        };
        return View();
    }
}

public class AppointmentData
{
    public int Id { get; set; }
    public string Subject { get; set; }
    public DateTime StartTime { get; set; }
    public DateTime EndTime { get; set; }
}

Common Patterns

Adding Events Programmatically

// Use addEvent method to create appointments
<script>
var scheduleObj = document.getElementById('schedule').ej2_instances[0];
scheduleObj.addEvent({
    Id: 2,
    Subject: 'New Meeting',
    StartTime: new Date(2024, 2, 28, 10, 0),
    EndTime: new Date(2024, 2, 28, 11, 0)
});
</script>

Handling CRUD Operations

// Server-side in DataManager with CrudUrl
var dataManager = new DataManager() {
    Url = "Home/GetData",
    Adaptor = "UrlAdaptor",
    CrudUrl = "Home/UpdateData",
    // Configure server-side CORS with explicit allowed origins rather than relying on a client-side CrossDomain flag.
};

Creating Recurring Events

// RecurrenceRule follows iCalendar (RFC 5545) format
new AppointmentData {
    Id = 1,
    Subject = "Daily Standup",
    StartTime = new DateTime(2024, 3, 28, 9, 0, 0),
    EndTime = new DateTime(2024, 3, 28, 9, 30, 0),
    RecurrenceRule = "FREQ=DAILY;INTERVAL=1;COUNT=10"
}

Configuring Multiple Views

<ejs-schedule id="schedule" currentView="Week">
    <e-schedule-views>
        <e-schedule-view option="Day"></e-schedule-view>
        <e-schedule-view option="Week"></e-schedule-view>
        <e-schedule-view option="Month"></e-schedule-view>
        <e-schedule-view option="TimelineDay"></e-schedule-view>
    </e-schedule-views>
</ejs-schedule>
