Rendering Changes in 15.0.0

Updated on Aug 11, 2026

Make sure that you are using a compatible Telerik CSS theme every time you upgrade Telerik UI for Blazor.

Scheduler

• The popup edit form has a new simpler and cleaner horizontal layout.
• The recurrence management UI is moved from the main edit form to a separate modal Dialog that shows up on button click in the main edit form. The recurrence Dialog has a CSS class .k-scheduler-recurrence-dialog.
• The default Scheduler toolbar has a New Event button that opens the popup edit form on the first date from the current view.
• The SchedulerToolBarNavigationTool renders flat buttons instead of solid buttons.
• The SchedulerToolBarViewsTool renders as a SegmentedControl on wide screens and as a DropDownButton on narrow screens.
• The appointment delete button is moved to the bottom of the popup edit form.
• The appointment recurrence and exception icons are moved to the bottom-right.
• The overflow button in the Month view shows how many appointments overflow, instead of three dots.
