SyncFusion Scheduler - struggling to obtain appointment details

问题

我有一个.Net MAUI应用程序（目标平台为Android、iOS和Windows），我正在尝试首次使用SyncFusion Scheduler。

我已经让一切都工作正常，但我在点击日程安排时难以获取预约详情。

XAML：

  1. <scheduler:SfScheduler x:Name="calendar" View="Month" FirstDayOfWeek="Monday" AllowedViews="Week,Month"   
  2.                        TodayHighlightBrush="Gray" AppointmentsSource="{Binding SchedulerEvents}" Tapped="calendar_Tapped">
  3.     <scheduler:SfScheduler.MonthView>
  4.         <scheduler:SchedulerMonthView AppointmentDisplayMode="Indicator"  />
  5.     </scheduler:SfScheduler.MonthView>
  6.     <scheduler:SfScheduler.BindingContext>
  7.         <local:SchedulerControlViewModel>
  8.             
  9.         </local:SchedulerControlViewModel>
  10.     </scheduler:SfScheduler.BindingContext>
  11. </scheduler:SfScheduler>

Code Behind：

  1. private void calendar_Tapped(object sender, SchedulerTappedEventArgs e)
  2. {
  3.     if (e.Appointments.Count < 0)
  4.     {
  5.         //没有预约 - 没问题
  6.     }
  7.     else
  8.     {
  9.         //点击的日期上有预约
  10.         //// 如何从e.Appointments中获取预约详情（例如预约主题）。
  11.     }
  12. }

ViewModel：

  1. namespace MyGolfSocietyApp.ViewModels
  2. {
  3.     public class SchedulerControlViewModel
  4.     {
  5.         public ObservableCollection<SchedulerAppointment> SchedulerEvents { get; set; }
  6.         public SchedulerControlViewModel()
  7.         {
  8.             this.SchedulerEvents = new ObservableCollection<SchedulerAppointment>
  9.             {
  10.                 new SchedulerAppointment
  11.                 {
  12.                     StartTime = new DateTime(2023, 8, 5, 00, 01, 01),
  13.                     EndTime = new DateTime(2023, 8, 5, 23, 01, 01),
  14.                     Subject = "测试预约",
  15.                     IsAllDay = true 
  16.                 }
  17.            };
  18.         }
  19.     }
  20. }

Tapped事件处理程序“calendar_Tapped”触发正常，但我难以获取预约内容。
我可以通过调试日志（立即窗口）看到数据从ViewModel返回：

  1. ?e.Appointments
  2. Count = 1
  3.     [0]: {Syncfusion.Maui.Scheduler.SchedulerAppointment}
  4. ?e.Appointments[0]
  5. {Syncfusion.Maui.Scheduler.SchedulerAppointment}
  6.     base: {Syncfusion.Maui.Scheduler.SchedulerRegionBase}
  7.     ActualEndTime: {System.DateTime}
  8.     ActualStartTime: {System.DateTime}
  9.     DataItem: (null)
  10.     EndTimeZone: {System.TimeZoneInfo}
  11.     Id: 311937363
  12.     IsAllDay: true
  13.     IsReadOnly: false
  14.     Location: ""
  15.     Notes: ""
  16.     RecurrenceId: (null)
  17.     Reminders: (null)
  18.     StartTimeZone: {System.TimeZoneInfo}
  19.     Subject: "测试预约"
  20.     Type: Syncfusion.Maui.Scheduler.SchedulerAppointmentType.Normal

I have a .Net MAUI app (target platform And, iOS & Win)
im trying to use the SyncFusion Scheduler for the first time..

I have everything working but I'm struggling to obtain appointment details when I tap on the scheduler..

XAML:

  1. &lt;scheduler:SfScheduler x:Name=&quot;calendar&quot; View=&quot;Month&quot; FirstDayOfWeek=&quot;Monday&quot; AllowedViews=&quot;Week ,Month&quot;   
  2.                              TodayHighlightBrush=&quot;Gray&quot; AppointmentsSource=&quot; {Binding SchedulerEvents}&quot; Tapped=&quot;calendar_Tapped&quot; &gt;
  4.             &lt;scheduler:SfScheduler.MonthView&gt;
  5.                 &lt;scheduler:SchedulerMonthView AppointmentDisplayMode=&quot;Indicator&quot;  /&gt;
  6.             &lt;/scheduler:SfScheduler.MonthView&gt;
  8.             &lt;scheduler:SfScheduler.BindingContext &gt;
  9.                 &lt;local:SchedulerControlViewModel&gt;
  10.                     
  11.                 &lt;/local:SchedulerControlViewModel&gt;
  12.             &lt;/scheduler:SfScheduler.BindingContext&gt;
  13. &lt;/scheduler:SfScheduler&gt;

Code Behind:

  1. private void calendar_Tapped(object sender, SchedulerTappedEventArgs e)
  2.     {
  5.        
  7.         if (e.Appointments.Count &lt; 0)
  8.         {
  9.             //No Appointment - no problem
  10.         }
  11.         else
  12.         {
  14.             //Appointment on date tapped
  16. 		//// HOW DO I GET THE APPOINTMENT DETAILS FROM e.Appointments (such as the appointment subject.
  17.         }
  19.     }

View Model:

  1. namespace MyGolfSocietyApp.ViewModels
  2. {
  3.     public class  SchedulerControlViewModel
  4.     {
  5.         public ObservableCollection&lt;SchedulerAppointment&gt; SchedulerEvents { get; set; }
  6.         public SchedulerControlViewModel()
  7.         {
  9.             this.SchedulerEvents = new ObservableCollection&lt;SchedulerAppointment&gt;
  10.             {
  11.                 new SchedulerAppointment
  12.                 {
  13.                     StartTime = new DateTime(2023, 8, 5,00,01,01),
  14.                     EndTime = new DateTime(2023, 8, 5,23,01,01),
  15.                     Subject = &quot;TEST Appointment&quot;,
  16.                     IsAllDay = true 
  17.  
  18.                 }
  19.            };
  21.         }
  23.     }
  24. }

The Tapped event handler "calendar_Tapped" triggers ok but im struggling to get the content of the Appointments..
im sure this is super basic c# but im really struggling - hoping you guys can help me please

I can see through the debug logs (immediate window) data is being retunred from the View Model:

  1. ?e.Appointments
  2. Count = 1
  3.     [0]: {Syncfusion.Maui.Scheduler.SchedulerAppointment}
  4. ?e.Appointments[0]
  5. {Syncfusion.Maui.Scheduler.SchedulerAppointment}
  6.     base: {Syncfusion.Maui.Scheduler.SchedulerRegionBase}
  7.     ActualEndTime: {System.DateTime}
  8.     ActualStartTime: {System.DateTime}
  9.     DataItem: (null)
  10.     EndTimeZone: {System.TimeZoneInfo}
  11.     Id: 311937363
  12.     IsAllDay: true
  13.     IsReadOnly: false
  14.     Location: &quot;&quot;
  15.     Notes: &quot;&quot;
  16.     RecurrenceId: (null)
  17.     Reminders: (null)
  18.     StartTimeZone: {System.TimeZoneInfo}
  19.     Subject: &quot;TEST Appointment&quot;
  20.     Type: Syncfusion.Maui.Scheduler.SchedulerAppointmentType.Normal

得分: 0

Appointments 是一个 object 集合

  1. public ReadOnlyCollection&lt;object&gt; Appointments { get; }

所以你需要进行强制类型转换

  1. ((SchedulerAppointment)e.Appointments[0]).Subject
英文:

Appointments is a collection of object

  1. public ReadOnlyCollection&lt;object&gt; Appointments { get; }

so you will need to cast it

  1. ((SchedulerAppointment)e.Appointments[0]).Subject
