+
+## Description
+
+I want to get the first and last date in my current Scheduler view. These start and end values should be updated when I change the view (DayView, WeekView, etc.), or when I navigate to a different date.
+
+## Solution
+
+Get these values using the `data-slot-start` and `data-slot-end` properties of the SchedulerSlot.
+
+First, retrieve the first and last slots using the `.k-scheduler-body .k-scheduler-cell.k-slot-cell` class, where the first item in the array represents the first slot while the last one represents the last one. This allows you to get the date value of the `data-slot-start` of the first slot, and `data-slot-end` of the last slot. This should be done in the [useEffect](https://react.dev/reference/react/useEffect) hook where the date and view should be added to the dependency array because we want the start and end dates to be updated when the view or date is updated.
+
+Following is an example demonstrates this approach:
