Day view is used to display a single day; current day will be visible by default. Appointments on a specific day will be arranged in respective timeslots based on its duration.

ViewHeader Appearance

You can customize the default appearance of view header in DayView by using ViewHeaderStyle property of SfSchedule.

C#

//Create new instance of Schedule
SfSchedule schedule = new SfSchedule(this);
schedule.ScheduleView = ScheduleView.DayView;
//Customize the schedule view header
ViewHeaderStyle viewHeaderStyle = new ViewHeaderStyle();
viewHeaderStyle.BackgroundColor = Color.Rgb(0, 150, 136);
viewHeaderStyle.DayTextColor = Color.Rgb(255, 255, 255);
viewHeaderStyle.DateTextColor = Color.Rgb(255, 255, 255);
viewHeaderStyle.DayTextStyle = Typeface.DefaultFromStyle(TypefaceStyle.Italic);
viewHeaderStyle.DateTextStyle = Typeface.DefaultFromStyle(TypefaceStyle.Italic);
schedule.ViewHeaderStyle = viewHeaderStyle;

You can customize the height of the ViewHeader in DayView by setting ViewHeaderHeight property of SfSchedule.

C#

schedule.ScheduleView = ScheduleView.DayView;
schedule.ViewHeaderHeight = 50;

Customize Font Appearance

You can change the appearance of Font by setting the DayTextStyle and DateTextStyle properties of ViewHeaderStyle property in Schedule.

C#

viewHeaderStyle.DayTextStyle = Typeface.CreateFromAsset(Assets, "Lobster-Regular");
viewHeaderStyle.DateTextStyle = Typeface.CreateFromAsset(Assets, "Lobster-Regular");

Refer this to configure the custom fonts in Xamarin.Android.

ViewHeader Date Format

You can customize the date and day format of SfSchedule ViewHeader by using DateFormat and DayFormat properties of DayLabelSettings.

C#

schedule.ScheduleView = ScheduleView.DayView;
//Creating new instance of DayViewSettings
DayViewSettings dayViewSettings = new DayViewSettings();
//Creating new instance of DayLabelSettings
DayLabelSettings dayLabelSettings = new DayLabelSettings();
//Customizing date format
dayLabelSettings.DateFormat = "dd";
dayLabelSettings.DayFormat = "EEEE";
dayViewSettings.DayLabelSettings = dayLabelSettings;
schedule.DayViewSettings = dayViewSettings;

ViewHeader Tapped Event

You can handle single tap action of ViewHeader by using ViewHeaderTapped event of SfSchedule. This event will be triggered when the ViewHeader is Tapped. This event contains ViewHeaderTappedEventArgs argument which holds Calendar details in it.

C#

//Creating  new instance of Schedule
SfSchedule schedule = new SfSchedule();
schedule.ScheduleView = ScheduleView.DayView;
schedule.ViewHeaderTapped += Handle_ViewHeaderTapped;

...

void Handle_ViewHeaderTapped(object sender, ViewHeaderTappedEventArgs e)
{
    var calendar = e.Calendar;
}

Change Time Interval

You can customize the interval of timeslots in DayView by setting TimeInterval property of SfSchedule.

C#

schedule.ScheduleView = ScheduleView.DayView;
schedule.TimeInterval = 120;

NOTE
If you modify the TimeInterval value (in minutes), you need to change the time labels format by setting the TimeFormat value as “hh:mm”. By default, TimeFormat value is "h a". You can refer here for changing TimeFormat value.

Change Time Interval Height

You can customize the interval height of timeslots in DayView by setting TimeIntervalHeight property of SfSchedule.

C#

schedule.ScheduleView = ScheduleView.DayView;
schedule.TimeIntervalHeight = 180;

Change Working hours

Working hours in DayView of Schedule control will be differentiated with non-working hours by separate color. By default, working hours will be between 09 to 18. You can customize the working hours by setting WorkStartHour and WorkEndHour properties of DayViewSettings. You can also customize the working hours along with minutes by setting double value which will be converted to time.

C#

schedule.ScheduleView = ScheduleView.DayView;
//Create new instance of DayViewSettings
DayViewSettings dayViewSettings = new DayViewSettings();
DayLabelSettings dayLabelSettings = new DayLabelSettings();
dayLabelSettings.TimeFormat = "hh:mm";
dayViewSettings.WorkStartHour = 11.5;
dayViewSettings.WorkEndHour = 17.5;
dayViewSettings.DayLabelSettings = dayLabelSettings;
schedule.DayViewSettings = dayViewSettings;

NOTE
No need to specify the decimal point values for WorkStartHour and WorkEndHour, if you don’t want to set the minutes.

Changing StartHour and EndHour

Default value for StartHour and EndHour value is 0 to 24 to show all the time slots in DayView. You need to set StartHour and EndHour property of DayView, to show only the required time duration for end users. You can also set StartHour and EndHour in double value which will be converted to time to show required time duration in minutes.

C#

schedule.ScheduleView = ScheduleView.DayView;
//Create new instance of DayViewSettings
DayViewSettings dayViewSettings = new DayViewSettings();
DayLabelSettings dayLabelSettings = new DayLabelSettings();
dayLabelSettings.TimeFormat = "hh:mm";
dayViewSettings.StartHour = 7.5;
dayViewSettings.EndHour = 18.5;
dayViewSettings.DayLabelSettings = dayLabelSettings;
schedule.DayViewSettings = dayViewSettings;

NOTE

• StartHour must be greater than or equal to 0 and EndHour must be lesser than or equal to 24, otherwise InvalidDataException will be thrown.
• EndHour value must be greater than StartHour, otherwise InvalidDataException will be thrown.
• Schedule UI such as Appointments and NonAccessibleBlocks 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 don’t 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 time interval is given, then the number of time slots calculated based on given time interval should result in integer value, otherwise given time interval will be neglected and default time interval (60 minutes) will be considered.
• If the custom start hour and end hour is given, then the number of time slots calculated based on given start hour, end hour should result in integer value, otherwise given end hour will be rounded off. For example, if StartHour is 7.2 (07:12AM), EndHour is 18.6 (06:36AM) and TimeInterval is 60 minutes, then EndHour will be rounded off to 18.2 (06:12PM).
