Getting Started with Blazor Scheduler Component

24 May 202216 minutes to read

This section briefly explains about how to include Blazor Scheduler component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

To get start quickly with Blazor Scheduler, you can check on this video:

Prerequisites

Create a new Blazor App in Visual Studio

You can create Blazor Server App or Blazor WebAssembly App using Visual Studio in one of the following ways,

Install Syncfusion Blazor Schedule NuGet in the App

Syncfusion Blazor components are available in nuget.org. To use Syncfusion Blazor components in the application, add reference to the corresponding NuGet. Refer to NuGet packages topic for available NuGet packages list with component details.

To add Blazor Scheduler component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.Blazor.Schedule and then install it.

Register Syncfusion Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor namespace.

@using Syncfusion.Blazor

Now, register the Syncfusion Blazor Service in the Blazor Server App or Blazor WebAssembly App. Here, Syncfusion Blazor Service is registered by setting IgnoreScriptIsolation property as true to load the scripts externally in the next steps.

From 2022 Vol1 (20.1) version - The default value of IgnoreScriptIsolation is changed as true, so, you don’t have to set IgnoreScriptIsolation property explicitly to refer scripts externally.

Blazor Server App

  • For .NET 6 app, open the ~/Program.cs file and register the Syncfusion Blazor Service.

  • For .NET 5 and .NET 3.X app, open the ~/Startup.cs file and register the Syncfusion Blazor Service.

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor(options => { options.IgnoreScriptIsolation = true; });

var app = builder.Build();
....
using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Startup
    {
        ...
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddRazorPages();
            services.AddServerSideBlazor();
            services.AddSyncfusionBlazor(options => { options.IgnoreScriptIsolation = true; });
        }
        ...
    }
}

Blazor WebAssembly App

Open ~/Program.cs file and register the Syncfusion Blazor Service in the client web app.

using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor(options => { options.IgnoreScriptIsolation = true; });
await builder.Build().RunAsync();
....
using Syncfusion.Blazor;

namespace WebApplication1
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            builder.Services.AddSyncfusionBlazor(options => { options.IgnoreScriptIsolation = true; });
            await builder.Build().RunAsync();
        }
    }
}

Add Style Sheet

Checkout the Blazor Themes topic to learn different ways (Static Web Assets, CDN and CRG) to refer themes in Blazor application, and to have the expected appearance for Syncfusion Blazor components. Here, the theme is referred using Static Web Assets. Refer to Enable static web assets usage topic to use static assets in your project.

To add theme to the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.Blazor.Themes and then install it. Then, the theme style sheet from NuGet can be referred as follows,

Blazor Server App

  • For .NET 6 app, add the Syncfusion bootstrap5 theme in the <head> of the ~/Pages/_Layout.cshtml file.

  • For .NET 5 and .NET 3.X app, add the Syncfusion bootstrap5 theme in the <head> of the ~/Pages/_Host.cshtml file.

<head>
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
<head>
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

Blazor WebAssembly App

For Blazor WebAssembly App, Refer the theme style sheet from NuGet in the <head> of wwwroot/index.html file in the client web app.

<head>
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

Add Script Reference

Checkout Adding Script Reference topic to learn different ways to add script reference in Blazor Application. In this getting started walk-through, the required scripts are referred using Static Web Assets externally inside the <head> as follows. Refer to Enable static web assets usage topic to use static assets in your project.

Blazor Server App

  • For .NET 6 app, Refer script in the <head> of the ~/Pages/_Layout.cshtml file.

  • For .NET 5 and .NET 3.X app, Refer script in the <head> of the ~/Pages/_Host.cshtml file.

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>
<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>

Blazor WebAssembly App

For Blazor WebAssembly App, Refer script in the <head> of the ~/index.html file.

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>

Syncfusion recommends to reference scripts using Static Web Assets, CDN and CRG by disabling JavaScript isolation for better loading performance of the Blazor application.

Add Blazor Scheduler component

  • Open ~/_Imports.razor file or any other page under the ~/Pages folder where the component is to be added and import the Syncfusion.Blazor.Schedule namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Schedule
  • Now, add the Syncfusion Scheduler component in razor file. Here, the Scheduler component is added in the ~/Pages/Index.razor file under the ~/Pages folder.
<SfSchedule TValue=AppointmentData>
    <ScheduleViews>
        <ScheduleView Option="View.Day"></ScheduleView>
        <ScheduleView Option="View.Week"></ScheduleView>
        <ScheduleView Option="View.WorkWeek"></ScheduleView>
        <ScheduleView Option="View.Month"></ScheduleView>
        <ScheduleView Option="View.Agenda"></ScheduleView>
    </ScheduleViews>
</SfSchedule>
@code {
    public class AppointmentData
    {
        public int Id { get; set; }
        public string Subject { get; set; }
        public string Location { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public string Description { get; set; }
        public bool IsAllDay { get; set; }
        public string RecurrenceRule { get; set; }
        public string RecurrenceException { get; set; }
        public Nullable<int> RecurrenceID { get; set; }
    }
}
  • Press Ctrl+F5 (Windows) or +F5 (macOS) to run the application. Then, the Syncfusion Blazor Scheduler component will be rendered in the default web browser.

Populating appointments

To populate the Scheduler with appointments, bind the event data to it by assigning the DataSource property under ScheduleEventSettings.

<SfSchedule TValue="AppointmentData" Height="650px" @bind-SelectedDate="@CurrentDate">
    <ScheduleEventSettings DataSource="@DataSource"></ScheduleEventSettings>
    <ScheduleViews>
        <ScheduleView Option="View.Day"></ScheduleView>
        <ScheduleView Option="View.Week"></ScheduleView>
        <ScheduleView Option="View.WorkWeek"></ScheduleView>
        <ScheduleView Option="View.Month"></ScheduleView>
        <ScheduleView Option="View.Agenda"></ScheduleView>
    </ScheduleViews>
</SfSchedule>

@code{
    DateTime CurrentDate = new DateTime(2020, 2, 14);
    List<AppointmentData> DataSource = new List<AppointmentData>
    {
        new AppointmentData { Id = 1, Subject = "Paris", StartTime = new DateTime(2020, 2, 13, 10, 0, 0) , EndTime = new DateTime(2020, 2, 13, 12, 0, 0) },
        new AppointmentData { Id = 2, Subject = "Germany", StartTime = new DateTime(2020, 2, 15, 10, 0, 0) , EndTime = new DateTime(2020, 2, 15, 12, 0, 0) }
    };
    public class AppointmentData
    {
        public int Id { get; set; }
        public string Subject { get; set; }
        public string Location { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public string Description { get; set; }
        public bool IsAllDay { get; set; }
        public string RecurrenceRule { get; set; }
        public string RecurrenceException { get; set; }
        public Nullable<int> RecurrenceID { get; set; }
    }
}

Blazor Scheduler with Appointments

Setting date

The Blazor Scheduler usually displays the system date as its current date. To change the current date of Scheduler with specific date, define the two-way binding for SelectedDate property.

<SfSchedule TValue="AppointmentData" Height="650px" @bind-SelectedDate="@CurrentDate">
    <ScheduleViews>
        <ScheduleView Option="View.Day"></ScheduleView>
        <ScheduleView Option="View.Week"></ScheduleView>
        <ScheduleView Option="View.WorkWeek"></ScheduleView>
        <ScheduleView Option="View.Month"></ScheduleView>
        <ScheduleView Option="View.Agenda"></ScheduleView>
    </ScheduleViews>
</SfSchedule>
@code{
    DateTime CurrentDate = new DateTime(2020, 1, 10);
    public class AppointmentData
    {
        public int Id { get; set; }
        public string Subject { get; set; }
        public string Location { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public string Description { get; set; }
        public bool IsAllDay { get; set; }
        public string RecurrenceRule { get; set; }
        public string RecurrenceException { get; set; }
        public Nullable<int> RecurrenceID { get; set; }
    }
}

Setting view

The Scheduler displays Week view by default. To change the current view, define the applicable view name to the two-way binding of CurrentView property. The applicable view names are,

  • Day
  • Week
  • WorkWeek
  • Month
  • Agenda
  • MonthAgenda
  • TimelineDay
  • TimelineWeek
  • TimelineWorkWeek
  • TimelineMonth
  • TimelineYear
  • Year
<SfSchedule TValue="AppointmentData" Height="650px" @bind-CurrentView="@CurrentView">
    <ScheduleViews>
        <ScheduleView Option="View.Day"></ScheduleView>
        <ScheduleView Option="View.Week"></ScheduleView>
        <ScheduleView Option="View.WorkWeek"></ScheduleView>
        <ScheduleView Option="View.Month"></ScheduleView>
        <ScheduleView Option="View.Agenda"></ScheduleView>
    </ScheduleViews>
</SfSchedule>
@code{
    View CurrentView = View.Month;
    public class AppointmentData
    {
        public int Id { get; set; }
        public string Subject { get; set; }
        public string Location { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public string Description { get; set; }
        public bool IsAllDay { get; set; }
        public string RecurrenceRule { get; set; }
        public string RecurrenceException { get; set; }
        public Nullable<int> RecurrenceID { get; set; }
    }
}

Individual view customization

Each individual Scheduler views can be customized with its own options such as setting different start and end hour on Week and Work Week views, whereas hiding the weekend days on Month view alone which can be achieved by defining the ScheduleView.

<SfSchedule TValue="AppointmentData" Height="650px" @bind-SelectedDate="@CurrentDate">
    <ScheduleViews>
        <ScheduleView Option="View.Week" StartHour="07:00" EndHour="15:00"></ScheduleView>
        <ScheduleView Option="View.WorkWeek" StartHour="10:00" EndHour="18:00"></ScheduleView>
        <ScheduleView Option="View.Month" MaxEventsPerRow="2" ShowWeekend="false"></ScheduleView>
    </ScheduleViews>
</SfSchedule>
@code{
    DateTime CurrentDate = new DateTime(2020, 2, 13);
    public class AppointmentData
    {
        public int Id { get; set; }
        public string Subject { get; set; }
        public string Location { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
        public string Description { get; set; }
        public bool IsAllDay { get; set; }
        public string RecurrenceRule { get; set; }
        public string RecurrenceException { get; set; }
        public Nullable<int> RecurrenceID { get; set; }
    }
}
