Blazor Scheduler Component in WebAssembly App using Visual Studio

10 Feb 20236 minutes to read

This article provides a step-by-step instructions for building Blazor WebAssembly App with Blazor Scheduler component using Visual Studio.

Prerequisites

Create a Blazor WebAssembly App in Visual Studio

You can create 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, Open ~/Program.cs file and register the Syncfusion Blazor Service in the client web app. Here, Syncfusion Blazor Service is registered by setting IgnoreScriptIsolation property as true to load the scripts externally in the next steps.

NOTE

From 2022 Vol-1 (20.1) version, the default value of IgnoreScriptIsolation is changed to true. It is not necessary to set the IgnoreScriptIsolation property to refer scripts externally, since the default value has already been changed to true, and this property is obsolete.

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();
await builder.Build().RunAsync();
....
using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            builder.Services.AddSyncfusionBlazor();
            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.

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 inside the <head> of wwwroot/index.html file in 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> of wwwroot/index.html file in client web app.

<head>
    ...
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="https://cdn.syncfusion.com/blazor/19.4.38/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>

NOTE

Syncfusion recommends to reference scripts using Static Web Assets, CDN and CRG by disabling JavaScript isolation for better loading performance of the Blazor application. Generate scripts and theme assets using CRG by selecting the components you were using in the 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" 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; }
    }
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion Blazor Scheduler component will be rendered in the default web browser.
