Icons

The default icon type in the Telerik UI for Blazor suite changes from FontIcon to SvgIcon. This marks the next milestone in a series of improvements related to the Content Security Policy (CSP).

All Telerik UI for Blazor components will now use SVG icons by default

When upgrading your application to 4.3.0 you might experience two possible scenarios related to the new default icon type:

Custom CSS that targets icons may stop working
Failing HTML tests

Changes In The Rendering

The built-in icons in Telerik UI for Blazor will now render with different HTML markup and CSS classes. This can break any CSS selectors that are targeting the icons:

UI for Blazor 4.2.0	UI for Blazor 4.3.0
`<span class="k-icon k-i-camera"></span>`	`<span class="k-svg-icon k-svg-i-camera"> <svg>...</svg> </span>`

Failing HTML Tests

If you are testing the rendered HTML by the Telerik UI for Blazor components, some tests will fail due to the Changes In the Rendering of the icons.

Continuing with FontIcons

To continue using FontIcons as the default icon type in the application, set the global icon type to Font.

As part of the R3 2023 release, the font icons will be detached from the Telerik UI for Blazor themes. To continue using the font icons in your application, either add a separate CDN reference or download and reference the stylesheet included in the Telerik UI for Blazor package.

`<a class="k-button-decrease">`	`<button class="k-button-decrease">`
`<a class="k-button-increase">`	`<button class="k-button-increase">`

Built-in Dialogs

In an attempt to unify the look and feel of our components, the action buttons in all built-in dialogs now follow a common set of guidelines:

Action buttons are now rendered inside a dedicated footer <div class="k-actions"> element.
The confirmation button always precedes the cancellation one, when such is present.
When part of a non-resizable dialog, the action buttons are stretched. Such an example is the Filter or the Column Menu.

Such dialogs are any edit forms, filter menus, column menus, editor's tools, as well as the TimePicker and DateTimePicker popups.
