Get started

Radzen Blazor Components are distributed as the Radzen.Blazor nuget package.

You can add them to your project in one of the following ways

• Install the package from command line by running dotnet add package Radzen.Blazor
• Add the project from the Visual Nuget Package Manager
• Manually edit the .csproj file and add a project reference

Open the _Imports.razor file of your Blazor application and add these two lines @using Radzen and @using Radzen.Blazor.

Open the _Host.cshtml file (server-side Blazor) or wwwroot/index.html (client-side WebAssembly Blazor) and include a theme CSS file by adding this snippet <link rel="stylesheet" href="_content/Radzen.Blazor/css/default-base.css"> This version requires only the Radzen Blazor CSS. Optionally you can include Bootstrap.

Alternatively you can include <link rel="stylesheet" href="_content/Radzen.Blazor/css/default.css"> which embeds Bootstrap.

Open the _Host.cshtml file (server-side Blazor) or wwwroot/index.html (client-side WebAssembly Blazor) and include this snippet <script src="_content/Radzen.Blazor/Radzen.Blazor.js"></script>

Use any Radzen Blazor component by typing its tag name in a Blazor page e.g. <RadzenButton Text="Hi"></RadzenButton>

If you are using client-side WebAssembly Blazor also add the following code to your .csproj file (after the closing RazorLangVersion element):

<BlazorLinkOnBuild>false</BlazorLinkOnBuild>

It is a workaround for a known issue when using IQueryable.

Data-binding a property

<RadzenButton Text="@text"></RadzenButton>
@code {
  string text = "Hi";
}

Handing events

<RadzenButton Click="@ButtonClicked" Text="Hi"></RadzenButton>
@code {
  void ButtonClicked()
  {
    //
  }
}

Open the Shared/MainLayout.razor file and include <RadzenDialog/>, <RadzenNotification/>, <RadzenContextMenu/> and <RadzenTooltip/>

Open the Startup.cs file (server-side Blazor) or Program.cs (client-side WebAssembly Blazor) and add DialogService, NotificationService, ContextMenuService and TooltipService.

Startup.cs (server-side Blazor)

    using Radzen;
    ...
    public void ConfigureServices(IServiceCollection services)
    {
        ...
        services.AddScoped<DialogService>();
        services.AddScoped<NotificationService>();
        services.AddScoped<TooltipService>();
        services.AddScoped<ContextMenuService>();
        ...
    }
    

Program.cs (client-side WebAssembly Blazor)

        using Radzen;
        ...
        public static async Task Main(string[] args)
        {
        var builder = WebAssemblyHostBuilder.CreateDefault(args);
        builder.RootComponents.Add<App>("app");

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

        ...

        builder.Services.AddScoped<DialogService>();
        builder.Services.AddScoped<NotificationService>();
        builder.Services.AddScoped<TooltipService>();
        builder.Services.AddScoped<ContextMenuService>();
        ...

        await builder.Build().RunAsync();
        }
