Breaking Changes in 4.0.0

Common Changes

This section applies to changes to multiple components.

Icons

Some built-in icons have been renamed. See the full list of changes in article New Icon Names in Telerik UI for Blazor 4.0.

Icon

The Icon parameter type changes from string to object to facilitate the addition of Telerik Font and Svg Icons.

To use built-in Telerik icons, register the new icon namespaces - Telerik.FontIcons or Telerik.SvgIcons.

To define custom icon classes inline, use Icon="@( "my-icon-class" )".

To use Telerik font icons with UI for Blazor 4.6.0 and above, register font-icons.css.
