Syntax
public class ScheduleToolBarPrevious : SfOwningComponentBase, IComponent, IHandleEvent, IHandleAfterRender, IDisposable
Remarks

This component is intended to be used as a child of ScheduleToolBar, which itself must be placed inside an SfSchedule<TValue>. When declared, it registers a previous navigation segment with the parent toolbar so that the header renderer reuses the built-in previous navigation logic for moving to the previous date range based on the current view (e.g., day, week, month).

Examples

Demonstrates how to configure the ScheduleToolBarPrevious to declare the previous navigation tool in the Scheduler.

<SfSchedule TValue="AppointmentData" @bind-SelectedDate="@SelectedDate">
    <ScheduleToolBar>
        <ScheduleToolBarPrevious />
    </ScheduleToolBar>
</SfSchedule>
@code {
    public class AppointmentData
    {
        public string Subject { get; set; }
        public DateTime StartTime { get; set; }
        public DateTime EndTime { get; set; }
    }
    private DateTime SelectedDate { get; set; } = DateTime.Today;
}
