Timeline Views in WinUI Scheduler (SfScheduler)

19 Apr 202223 minutes to read

The TimelineView displays the dates in the horizontal time axis with the desired day’s count. Scheduler supports displaying the TimelineDay, TimelineWeek, TimelineWorkWeek, and TimelineMonth views. See the past or future dates by scrolling to the right or left. Each view displays the events accurately across the time slots with an intuitive drag-and-drop feature. It provides the support to highlight the selected region of time slots and handle the interaction.

Change time interval

Customize the interval of timeslots in the timeline views by using the TimeInterval property of TimelineViewSettings. This property will be applicable to TimelineDay, TimelineWeek, and TimelineWorkWeek views.

<scheduler:SfScheduler x:Name="Schedule" 
                       ViewType="TimelineWeek" >
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
this.Schedule.TimelineViewSettings.TimeInterval = new System.TimeSpan(0, 120, 0);

change-time-interval-in-winui-scheduler

NOTE

If the timeInterval value is modified (in minutes), change the time labels format by setting the timeFormat value to hh:mm.

Change time interval width

Customize the interval width of timeslots in the Timeline views by setting the TimeIntervalSize property of TimelineViewSettings. This property will be applicable to all timeline views. By default, it’s value is 50 for the TimelineDay, TimelineWeek, and TimelineWorkWeek views and 150 for TimelineMonth view.

<scheduler:SfScheduler x:Name="Schedule" ViewType="TimelineWeek">
    <scheduler:SfScheduler.TimelineViewSettings>
        <scheduler:TimelineViewSettings 
            TimeIntervalSize="120"/>
    </scheduler:SfScheduler.TimelineViewSettings>
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
this.Schedule.TimelineViewSettings.TimeIntervalSize = 120;

Flexible working days

By default, the WinUI Scheduler considers the week days from Monday to Friday as Working days. The days which are defined in this non-working days collection are considered as non-working days. Therefore, when the weekend days are set to hide from Scheduler.

The Timeline workweek view displays exactly the defined working days on Scheduler control, whereas other views displays all the days.

<scheduler:SfScheduler x:Name="Schedule" ViewType="TimelineWeek">
    <scheduler:SfScheduler.TimelineViewSettings>
        <scheduler:TimelineViewSettings 
             NonWorkingDays="Monday,Tuesday"/>
    </scheduler:SfScheduler.TimelineViewSettings>
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWorkWeek;
this.Schedule.TimelineViewSettings.NonWorkingDays = new ObservableCollection<DayOfWeek>() { DayOfWeek.Monday, DayOfWeek.Tuesday };

flexible-working-days-in-winui-scheduler

Flexible working hours

The default values for the StartHour and EndHour are 0 and 24 to show all the time slots in a timeline view. Set the StartHour and EndHour properties of TimelineViewSettings to show only the required time duration for users. Set the StartHour and EndHour in time duration to show the required time duration in minutes. The StartHour and EndHour properties do not apply to the TimelineMonth view.

<scheduler:SfScheduler x:Name="Schedule" ViewType="TimelineWeek">
    <scheduler:SfScheduler.TimelineViewSettings>
        <scheduler:TimelineViewSettings 
            StartHour="8"
            EndHour="13"/>
    </scheduler:SfScheduler.TimelineViewSettings>
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
this.Schedule.TimelineViewSettings.StartHour = 8;
this.Schedule.TimelineViewSettings.EndHour = 16;

flexible-working-hours-in-winui-scheduler

NOTE

  • The NonWorkingDays property will be applicable only for workWeek and TimelineWorkWeek views only, and not applicable for the remaining views.
  • The Scheduler Appointments UI, which does not fall within the StartHour and EndHour will not be visible and if it falls partially, it will be clipped.
  • No need to specify the decimal point values for StartHour and EndHour if you do not want to set the minutes.
  • The number of time slots will be calculated based on total minutes of a day and time interval (total minutes of a day ((start hour - end hour) * 60) / time interval).
    If the custom timeInterval is given, then the number of time slots calculated based on the given TimeInterval should result in an integer value (total minutes % timeInterval = 0). Otherwise, the next immediate time interval that results in integer value when dividing total minutes of a day will be considered. For example, if TimeInterval= 2 Hours, 15 minutes and total minutes = 1440 (24 Hours per day), then the TimeInterval will be changed to ‘144’ (1440%144=0) by considering (total minutes % TimeInterval = 0), it will return integer value for time slots rendering.
  • If the custom StartHour and EndHour are given, then the number of time slots calculated based on given StartHour and EndHour should result in integer value, otherwise next immediate TimeInterval will be considered until the result is integer value. For example, if StartHour is 9 (09:00AM), EndHour is 18.25 (06:15 PM), TimeInterval is 30 minutes, and total minutes = 555 ((18.25-9)*60), then the TimeInterval will be changed to ’37 minutes’ (555%37=0) by considering (total minutes % timeInterval = 0). It will return integer value for time slots rendering.

Change days count

Change the day’s count of timeslots in the timeline view by setting the DaysCount property of TimelineViewSettings. This property is only applicable for the TimelineDay view. By default, its value is set to 1.

<scheduler:SfScheduler x:Name="Schedule" ItemsSource="{Binding Appointments}" ViewType="TimelineDay">
    <scheduler:SfScheduler.TimelineViewSettings>
        <scheduler:TimelineViewSettings 
            DaysCount="2"/>
    </scheduler:SfScheduler.TimelineViewSettings>
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineDay;
this.Schedule.TimelineViewSettings.DaysCount = 2;

Blackout dates

Disable the interaction for certain dates in the scheduler TimelineMonth view by adding those specific dates to the BlackoutDates collection property of SfScheduler. Using this, allocate or restrict the specific dates for predefined events. This property does not apply to the TimelineDay, TimelineWeek, and TimelineWorkWeek views.

<scheduler:SfScheduler x:Name="Schedule" ViewType="TimelineMonth">
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineMonth;
this.Schedule.BlackoutDates = GetBlackoutDates();

/// <summary>
/// Method to get all blackout date collections.
/// </summary>
private ObservableCollection<DateTime> GetBlackoutDates()
{
    var blackoutDateCollection = new ObservableCollection<DateTime>()
    {
        DateTime.Now.Date.AddDays(-1),
        DateTime.Now.Date.AddDays(-3),
        DateTime.Now.Date.AddDays(-4),
        DateTime.Now.Date.AddDays(1),
        DateTime.Now.Date.AddDays(3),
        DateTime.Now.Date.AddDays(5)
    };
    return blackoutDateCollection;
}

Special time regions

Restrict the user interaction such as selection and highlights specific regions of time in the timeline views by adding the SpecialTimeRegions property of SfScheduler. Set the StartTime and EndTime properties of SpecialTimeRegion to create a SpecialTimeRegion, use the timeZone property to set the specific timezone for the start and end time of the SpecialTimeRegion. The SpecialTimeRegion will display the text or image on it that set to the text or icon property of SpecialTimeRegion. This property will be applicable to the TimelineDay, TimelineWeek, and TimelineWorkWeek views.

Selection restriction in timeslots

Enable or disable the touch interaction of SpecialTimeRegion using the CanEdit property of SpecialTimeRegion. By default, its value is set to true.

<scheduler:SfScheduler x:Name="Schedule" 
                       ViewType="TimelineWeek" >
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
this.Schedule.TimelineViewSettings.SpecialTimeRegions.Add(new SpecialTimeRegion
{
    StartTime = new System.DateTime(2021, 03, 26, 13, 0, 0),
    EndTime = new System.DateTime(2021, 03, 26, 14, 0, 0),
    Text = "Lunch",
    CanEdit = false,
    Background = new SolidColorBrush(Colors.LightGray),
    Foreground = new SolidColorBrush(Colors.White)
});

selection-restriction-in-timeslots-in-winui-scheduler

NOTE

This property only restricts the interaction on region and it does not restrict the following:

  • Programmatic selection (if the user updates the selected date value dynamically).
  • Does not clear the selection when the user selects the region and dynamically changes the CanEdit property to false.
  • It does not restrict the appointment interaction when the appointment is placed in the region.
  • It does not restrict the appointment rendering on a region when the appointments are loaded from data services or adding programmatically.

Recurring time region

The recurring time region on a daily, weekly, monthly, or yearly interval. The recurring special time regions can be created by setting the RecurrenceRule property in SpecialTimeRegion.

<scheduler:SfScheduler x:Name="Schedule" 
                       ViewType="TimelineWeek" >
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
this.Schedule.TimelineViewSettings.SpecialTimeRegions.Add(new SpecialTimeRegion
{
    StartTime = new System.DateTime(2021, 03, 21, 13, 0, 0),
    EndTime = new System.DateTime(2021, 03, 21, 14, 0, 0),
    Text = "Lunch",
    CanEdit = false,
    Background = new SolidColorBrush(Colors.LightGray),
    Foreground = new SolidColorBrush(Colors.White),
    RecurrenceRule = "FREQ=DAILY;INTERVAL=1"
});

Recurrence exception dates

Delete any of occurrence that is an exception from the recurrence pattern time region by using the RecurrenceExceptionDates property of SpecialTimeRegion. The deleted occurrence date will be considered as a recurrence exception date.

<scheduler:SfScheduler x:Name="Schedule" 
                       ViewType="TimelineWeek" >
</scheduler:SfScheduler>
this.Schedule.ViewType = SchedulerViewType.TimelineWeek;
DateTime recurrenceExceptionDates = DateTime.Now.Date.AddDays(-1);
DateTime recurrenceExceptionDates1 = DateTime.Now.Date.AddDays(2);
this.Schedule.TimelineViewSettings.SpecialTimeRegions.Add(new SpecialTimeRegion
{
    StartTime = new System.DateTime(2021, 03, 26, 12, 0, 0),
    EndTime = new System.DateTime(2020, 03, 26, 13, 0, 0),
    Text = "Lunch",
    CanEdit = false,
    Background = new SolidColorBrush(Colors.LightGray),
    Foreground = new SolidColorBrush(Colors.White),
    RecurrenceRule = "FREQ=DAILY;INTERVAL=1",
    RecurrenceExceptionDates = new ObservableCollection<DateTime>()
    {
        recurrenceExceptionDates,
        recurrenceExceptionDates1,
    }
});

Special time region customization

The SpecialTimeRegion background color can be customized by using the Background and SpecialTimeRegionTemplate properties of SpecialTimeRegion that is used to customize the text style for the image of the SpecialTimeRegion.
