Button Icons

You can put an image, sprite or a font icon in the button to illustrate its purpose for your end users. To apply them, use the following properties:

• for a font icon, use the Icon attribute to set the font icon class.
• for an image, use the ImageUrl attribute to provide the URL
• for a sprite, set the SpriteClass attribute to k-icon MySpriteClass where MySpriteClass defines the CSS rules for the sprite.

You can see how to use the built-in icons in the Font Icons article.

For a custom font icon, define the font and glyph in your Icon CSS class.

The following example shows how to use an image from a URL, a sprite image, and the built-in font icons.

How to use icons in Telerik Button

<TelerikButton SpriteClass="k-icon netherlandsFlag">Sprite</TelerikButton>
<TelerikButton Icon="filter">Font Icon</TelerikButton>
<TelerikButton ImageUrl="https://docs.telerik.com/blazor-ui/images/snowboarding.png">Image URL</TelerikButton>

<style>
    /* the sprite for the first button is defined through a CSS rule matchin its Class */
    .netherlandsFlag {
        background-image: url("https://docs.telerik.com/blazor-ui/images/flags.png");
        background-position: 0 -64px;
    }
</style>

The result from the code snippet above

You can use relative paths to your images in the wwwroot folder. The example above uses absolute paths to make it easy for you to see the results without preparing images.

If you don't add text to the button, the button will center the icon on all sides.

Images used as icons should generally be small enough to fit in a line of text - the button is an inline element and is not designed for large images. If you want to use big icon buttons, consider one of the following options:

• defining a Class on the button that provides height and width. The width and height can be set in px sufficient to accommodate the icon or to auto,
• or attaching an @onclick handler to an icon/span/img element instead of using a button,
• or adding your own HTML inside the button, something like: <TelerikButton><img style="width: 400px; height: 400px;" src="my-icon.svg" />some text</TelerikButton>
