How to show time indicator in WinUI Scheduler ?
Show the popup at a specific time when you drag and drop the appointment in the WinUI WinUI Scheduler by using the ShowTimeIndicator property of the DragandDropSettings in an AppointmentDragOver event in the Scheduler.
C#
Create a custom class Meeting with mandatory fields From, To, EventName and color.
public class Meeting : INotifyPropertyChanged
{
private string eventName;
private bool allDay;
private Brush color;
private DateTime to;
private DateTime from;
}
C#
Create a ViewModel class and add the appointment details.
public class SchedulerViewModel : INotifyPropertyChanged
{
private ObservableCollection<Meeting> meetings;
public SchedulerViewModel()
{
Meetings = new ObservableCollection<Meeting>();
Meeting meeting = new Meeting();
meeting.From = DateTime.Today.AddHours(13);
meeting.To = meeting.From.AddHours(1);
meeting.EventName = "Anniversary";
meeting.AllDay = false;
meeting.Color = new SolidColorBrush(Colors.Green);
Meetings.Add(meeting);
}
}
XAML
Bind the appointments to a schedule using the ItemsSource property, and enable the appointment drag and drop by setting the AppointmentEditFlag as DragDrop.
<Grid>
<Grid.DataContext>
<local:SchedulerViewModel/>
</Grid.DataContext>
<scheduler:SfScheduler
x:Name="Schedule"
ViewType="Week"
ItemsSource="{Binding Meetings}"
AppointmentEditFlag="DragDrop"
AppointmentDragOver="OnAppointmentDragOver">
<scheduler:SfScheduler.AppointmentMapping>
<scheduler:AppointmentMapping
StartTime="From"
EndTime="To"
Subject="EventName"
AppointmentBackground="Color"
IsAllDay="AllDay" >
</scheduler:AppointmentMapping>
</scheduler:SfScheduler.AppointmentMapping>
</scheduler:SfScheduler>
</Grid>
C#
The ShowTimeIndicator property updated in the AppointmentDragOver event is based on the dragging time.
//Event Customization
private void OnAppointmentDragOver (object sender, AppointmentDragOverEventArgs e)
{
if(e.DraggingTime.Minute == 30 || e.DraggingTime.Minute == 00)
{
this.Schedule.DragDropSettings.ShowTimeIndicator = true;
}
else
this.Schedule.DragDropSettings.ShowTimeIndicator = false;
}
