[shiva]

Hi ,

i have Few Query regarding Syncfuion Scheduler . 

 i am using syncfuion Scheduler in my app , i tried to bind my real data to the control so i used used your online documentation 1.2.2.2 Using Data Binding technique . There i am getting one exception regarding scheduler  . i would like to know how i can resolved that , i am using below code for that 

   protected async override void OnNavigatedTo(NavigationEventArgs e)

{

            scheduler.ScheduleType = ScheduleType.Month;

            List<AppointemenTabletdata> lstappointment = new List<AppointemenTabletdata>();

//this GetAppointment will give me real data 

            lstappointment = await GetAppointment();

            MappedAppointments = new ObservableCollection<AppointemenTabletdata>();

            for (int i = 0; i < lstappointment.Count; i++)

            {

                this.MappedAppointments.Add(new AppointemenTabletdata { Subject = lstappointment[i].Subject, StartTime = (lstappointment[i].StartTime), EndTime = (lstappointment[i].EndTime), Note = lstappointment[i].Note });

            };

            this.DataContext = this;

}

Note : this is i am using on Navigation but you have given in Constructor . 

Xaml code 

///

   <Schedule:SfSchedule x:Name="scheduler"  

                               ItemsSource="{Binding MappedAppointments}"

                 IntervalHeight="30" Background="WhiteSmoke" CurrentDateBackground="#63A028"  HeaderBackground="#FF25A0DA"   ScheduleType="Month" Margin="0,0,0,51" >

            <Schedule:SfSchedule.AppointmentMapping>

                <Schedule:ScheduleAppointmentMapping SubjectMapping="Subject" StartTimeMapping="StartTime"  EndTimeMapping="EndTime" NotesMapping="Note">

                </Schedule:ScheduleAppointmentMapping>

            </Schedule:SfSchedule.AppointmentMapping>

            

        </Schedule:SfSchedule>

Before that error it has binding the data Properly but now i am getting this exception 

System.NullReferenceException: Object reference not set to an instance of an object.

   at Syncfusion.UI.Xaml.Schedule.ScheduleMonthAppointmentViewControl.ScheduleMonthAppointmentViewControl_Loaded(Object sender, RoutedEventArgs e)

in my App.g.i.cs page .

I have Attached the Exception Image .

2- > one more thing is that earlier i could able to bind the data but i dont know how to update into my db after clicking on save or how to delete the Appointment if i am clicking Delete Button of our Add Event Flyout.

Hi Shiva,

 

We appreciate your patience.

 

Query #1 : Regarding Null reference exception.

 

We are not able to reproduce the mentioned issue in our current version v11.3.0.32. You can download it from the following link.

 

http://www.syncfusion.com/support/forums/winrt/113596/Syncfusion-Essential-Studio-for-WinRT-(XAML)-v113032-(Service-Pack)-available-for-download

 

We have also attached a simple sample for the same. Please find the sample in the attachment. In the provided sample we have used the Mapping feature of Schedule to Map the data available in SQLlite.

 

Note: You have to build one target for each. Select Build|Configuration Manager and select x86, x64 or ARM from the Platform drop-down list. (So that we can avoid warnings from the SQLite reference).

If the provided solution doesn't meet your requirement, please revert us back with more information about the reproducing scenario, so we could analyse on it more and provide your possible solution.

 

Query #2: Events for Delete and Save Button.

 

Currently we don’t have any special events to listen the “Save” and “Delete” button click. But your requirement can be achieve by the custom editor support. For the please refer the below sample

 

Dashboard -> WinRT -> Schedule -> CustomizationDemo

 

In the above sample, we have listened the delete and save button click events.

 

Please let us know, if you need any further assistance.

Do you have any update on this? I've a collection and when I bind to Schedule control, I'm getting following error:

System.NullReferenceException: Object reference not set to an instance of an object.

   at Syncfusion.UI.Xaml.Schedule.ScheduleMonthAppointmentViewControl.ScheduleMonthAppointmentViewControl_Loaded(Object sender, RoutedEventArgs e)

Although, this error occurs when I switch to control. i.e. when it receives focus. Data is perfects and binds well.
