Hi Alex,

Here is the code for the event trigger, this is put in the xaml

</ig:XamScheduleDataManager>

......... all the usual stuff here

 <ei:Interaction.Triggers>
        <ei:EventTrigger EventName="Loaded">
                <ei:InvokeCommandAction
                       Command="{Binding CalendarLoadedCommand}"
                       CommandParameter="{Binding CalendarGroups, ElementName=DataManager}"/>
           </ei:EventTrigger>
 </ei:Interaction.Triggers>

</ig:XamScheduleDataManager>

In the view model you have the following

 public ICommand CalendarLoadedCommand
        {
            get
            {
                if (_calendarLoadedCommand == null)
                {
                    _calendarLoadedCommand = new RelayCommand(
                        param => CalendarLoaded(param)
                    );
                }
                return _calendarLoadedCommand;
            }
        }

Then the method called by command, retrieves param and stores to local variable

 private CalendarGroupCollection _calendarGroups = new CalendarGroupCollection();

 private void CalendarLoaded(object param)
        {
            _calendarGroups = (CalendarGroupCollection)param;
        }

And then I have a method which is called by my code where I need to create the groups and all it does is add it to this private collection and that's it job done.

private void CreateCalendarGroups(ResourceCalendar calendar)
        {
            CalendarGroup groupWithCalendarAdded =
                            _calendarGroups.FirstOrDefault(cg => cg.Calendars.Contains(calendar));
            if (groupWithCalendarAdded != null)
            {
                groupWithCalendarAdded.Calendars.Remove(calendar);
                if (groupWithCalendarAdded.Calendars.Count == 0)
                    _calendarGroups.Remove(groupWithCalendarAdded);
            }
                
            CalendarGroup calGroup;
            if (_calendarGroups.Count > 0)
            {
                int index = 0;
                calGroup = _calendarGroups[index];
                calGroup.Calendars.Add(calendar);
            }
            else
            {
                calGroup = new CalendarGroup();
                calGroup.Calendars.Add(calendar);
                _calendarGroups.Add(calGroup);
            }
        }

Any questions just drop a message here, apologies for the delay I was on leave.

Hello Alex,

I have been looking into your post and would you please explain what code snippet you want exactly ?

If it is not regarding the discussed topic, please create a new thread.

Would you please post code snippet for event trigger? Thanks

Hello Anne,

You can easy determine it by handling ‘PreviewMouseUp’ event of the XamScheduleView  like :

   private void scheduleView_PreviewMouseUp(object sender, MouseButtonEventArgs e)

        {

            if (this.scheduleView.SelectedActivities.Count != 0 && this.scheduleView.SelectedActivities[0] is Appointment)

            {

                Appointment app = this.scheduleView.SelectedActivities[0] as Appointment;

            }

        }

Please in future create a separate thread for each of your questions.

Let me know, if you need any further assistance on this matter.

Is there a way to determine which appointment selected?
