How to show time indicator on a specific time when dragging an appointment in WPF Scheduler?
You can show the popup on specific time when do drag and drop the appointment in WPF SfScheduler by using the ShowTimeIndicator property of DragandDropSettings in a AppointmentDragOver event in WPF 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 = Brushes.Green;
Meetings.Add(meeting);
}
}
XAML
Bind the appointments to a schedule using the Scheduler.ItemsSource property and enable the appointment drag and drop by setting the AppointmentEditFlag as DragDrop
<Window.DataContext>
<local:SchedulerViewModel/>
</Window.DataContext>
<Grid>
<syncfusion:SfScheduler
x:Name="Schedule"
ViewType="Week"
ItemsSource="{Binding Meetings}"
AppointmentEditFlag="DragDrop">
<syncfusion:SfScheduler.AppointmentMapping>
<syncfusion:AppointmentMapping
StartTime="From"
EndTime="To"
Subject="EventName"
AppointmentBackground="Color"
IsAllDay="AllDay" >
</syncfusion:AppointmentMapping>
</syncfusion:SfScheduler.AppointmentMapping>
<interactivity:Interaction.Behaviors>
<local:SchedulerBehavior/>
</interactivity:Interaction.Behaviors>
</syncfusion:SfScheduler>
</Grid>
C#
ShowTimeIndicator property updated in the AppointmentDragOver event based on the dragging time.
public class SchedulerBehavior : Behavior<SfScheduler>
{
SfScheduler scheduler;
protected override void OnAttached()
{
base.OnAttached();
scheduler = this.AssociatedObject;
this.AssociatedObject.AppointmentDragOver += Scheduler_AppointmentDragOver;
}
private void Scheduler_AppointmentDragOver(object sender, AppointmentDragOverEventArgs e)
{
if (e.DraggingTime.Minute == 30 || e.DraggingTime.Minute == 00)
{
this.AssociatedObject.DragDropSettings.ShowTimeIndicator = true;
}
else
this.AssociatedObject.DragDropSettings.ShowTimeIndicator = false;
}
protected override void OnDetaching()
{
base.OnDetaching();
this.AssociatedObject.AppointmentDragOver -= Scheduler_AppointmentDragOver;
this.scheduler = null;
}
}
