This article provides a step-by-step instructions for building Blazor Server App with Blazor Calendar component using Visual Studio, Visual Studio Code and .NET CLI.

Using Playground

Blazor Playground allows you to interact with our Blazor components directly in your web browser without need to install any required NuGet packages. By default, the Syncfusion.Blazor package is included in this.

Manually Creating a Project

This section provides a brief explanation on how to manually create a Blazor Server App using Visual Studio, Visual Studio Code and .NET CLI.

Prerequisites

Create a new Blazor Server App in Visual Studio

You can create a Blazor Server App using Blazor Web App template in Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension.

Install Syncfusion® Blazor Calendars and Themes NuGet in the App

Here’s an example of how to add Blazor Calendar component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Calendars and Syncfusion.Blazor.Themes. Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.Calendars -Version 30.2.4
Install-Package Syncfusion.Blazor.Themes -Version 30.2.4

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Prerequisites

Create a new Blazor Server App in Visual Studio Code

You can create a Blazor Server App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension.

Alternatively, you can create a Server application using the following command in the terminal(Ctrl+`).

dotnet new blazor -o BlazorApp -int Server
cd BlazorApp

This command creates new Blazor app project and places it in a new directory called BlazorApp inside your current location. See Create Blazor app topic and dotnet new command topics for more details.

Install Syncfusion® Blazor Calendars and Themes NuGet in the App

  • Press Ctrl+` to open the integrated terminal in Visual Studio Code.
  • Ensure you’re in the project root directory where your .csproj file is located.
  • Run the following command to install a Syncfusion.Blazor.Calendars and Syncfusion.Blazor.Themes NuGet package and ensure all dependencies are installed.
dotnet add package Syncfusion.Blazor.Calendars -Version 30.2.4
dotnet add package Syncfusion.Blazor.Themes -Version 30.2.4
dotnet restore

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Prerequisites

Latest version of the .NET Core SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet --version

Create a new Blazor Server App in .NET CLI

Run the dotnet new blazor command to create a new Blazor Server application in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet new blazor -o BlazorApp -int Server
cd BlazorApp

This command creates new Blazor app project and places it in a new directory called BlazorApp inside your current location. See Create Blazor app topic and dotnet new CLI command topics for more details.

Install Syncfusion® Blazor Calendars and Themes NuGet in the App

Here’s an example of how to add Blazor Calendar component in the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a Syncfusion.Blazor.Calendars and Syncfusion.Blazor.Themes NuGet package. See Install and manage packages using the dotnet CLI topics for more details.

dotnet add package Syncfusion.Blazor.Calendars -Version 30.2.4
dotnet add package Syncfusion.Blazor.Themes -Version 30.2.4
dotnet restore

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Add Import Namespaces

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

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Calendars

Register Syncfusion® Blazor Service

Register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Server App.

....
....
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
....
....
builder.Services.AddSyncfusionBlazor();

....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script in the <head> and the script reference at the end of the <body> in the App.razor file as shown below:

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

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion® Blazor component

Add the Syncfusion® Blazor Calendar component in the ~/Components/Pages/Home.razor file. If an interactivity location as per page/component, define a render mode at the top of the Home.razor page.

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Server, the render mode is configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveServer

<SfCalendar TValue="DateTime" />
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Calendar component in your default web browser.
