Get started with Radzen Blazor Components

1. Install

Radzen Blazor Components are distributed as a 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

2. Import the namespace

Open the _Imports.razor file of your Blazor application and add this line @using Radzen.Blazor.

3. Include a theme

Radzen Blazor components come with five free themes: Material, Standard, Default, Dark, Software and Humanistic.

To use a theme

  1. Pick a theme. The online demos allow you to preview the available options via the theme dropdown located in the header. The Material theme is currently selected by default.
  2. Include the theme CSS file in your Blazor application. Open Pages\_Layout.cshtml (Blazor Server .NET 6), Pages\_Host.cshtml (Blazor Server .NET 7) or wwwroot/index.html (Blazor WebAssembly) and include a theme CSS file by adding this snippet
    <link rel="stylesheet" href="_content/Radzen.Blazor/css/material-base.css">

To include a different theme (i.e. Standard) just change the name of the CSS file:

<link rel="stylesheet" href="_content/Radzen.Blazor/css/standard-base.css">

4. Include Radzen.Blazor.js

Open Pages\_Layout.cshtml (Blazor Server .NET 6), Pages\_Host.cshtml (Blazor Server .NET 7) or wwwroot/index.html (Blazor WebAssembly) and include this snippet:

<script src="_content/Radzen.Blazor/Radzen.Blazor.js"></script>

5. Use a component

Use any Radzen Blazor component by typing its tag name in a Blazor page e.g.

<RadzenButton Text="Hi"></RadzenButton>

Data-binding a property

<RadzenButton Text=@text />
<RadzenTextBox @bind-Value=@text />
@code {
  string text = "Hi";

Handing events

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


Run demos locally

Use Radzen.Server.sln to open and run demos as Blazor server application or Radzen.WebAssembly.sln to open and run demos as Blazor WebAssembly application. Radzen.sln has reference to all projects including tests.
