Standalone Icon Component

Telerik UI for Blazor comes with the TelerikIcon component that you can use to render icons. It works with the following image types:

  • Telerik font icon - the Telerik.Blazor.IconName static class allows you to supply an Icon parameter that takes a Telerik icon from our built-in collection. To find the available Telerik icons, you can:

    Telerik UI for Blazor uses the same icons as the Kendo UI suite. You can find the rendered icons in the Kendo UI Web Font Icons Library article. When you use the icon names in this article, remove the k-i- prefix, and you will get the correct icon name for Blazor UI. You can use them as hardcoded strings as well. Their corresponding class members are in CamelCase.

  • Third party font-icon - the IconClass parameter lets you set a CSS class that provides the required font name, font size and content for the ::before pseudoelement.

  • Raster image - the ImageUrl is a string points to the image - it can be a path relative to the wwwroot folder, or an absolute URL.

  • Raster image sprite - the SpriteClass parameter lets you provide the classes from your site's stylesheet that produce the desired appearance and background positions for your sprites.

Render a standalone icon through the TelerikIcon component

<TelerikIcon Icon="@IconName.Audio" /> @* will render the audio note icon *@

@* <TelerikIcon Icon="audio" /> *@ @* This would also render the same audio icon *@

<TelerikIcon IconClass="oi oi-home" /> @* home icon from OpenIconic, assuming you have loaded the font on the page, you can use your own CSS classes and font icon fonts *@

<TelerikIcon ImageUrl="https://docs.telerik.com/blazor-ui/images/snowboarding.png" /> @* an image by URL, renders an actual <img /> tag *@

Icon Parameters - Order of Precedence

The priority order of the Icon properties, if more than one is defined, is:

  1. ImageUrl
  2. Icon
  3. IconClass
  4. SpriteClass

This order applies to other components that expose the same parameters, such as the TelerikButton or the grid command buttons.

Icon in Telerik Component

Some Telerik components expose icon features out-of-the box. These parameters match the TelerikIcon component described above.
