A set of 60+ free and open source native Blazor UI controls.

Radzen Blazor Components are open source and free for commercial use. You can install them from nuget or build your own copy from source.

Paid support is available as part of the Radzen Professional subscription.

The components are implemented in C# and take full advantage of the Blazor framework. They do not depend on or wrap existing JavaScript frameworks or libraries.

Blazor Server and Blazor WebAssembly are fully supported.

We add new components and features on a regular basis.

Short development cycle. We release as soon as new stuff is available. No more quarterly releases.

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 before .NET 6) or wwwroot/index.html (Blazor WebAssembly) and include the CSS file of 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">

Open Pages\_Layout.cshtml (Blazor Server .NET 6+), Pages\_Host.cshtml (Blazor Server before .NET 6) or wwwroot/index.html (Blazor WebAssembly) 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>

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

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

  }
}
