How to use custom appointment?

[anatoly]

Hi,

I've tried to use custom appointment calss similar to RadScheduler as described here but not successfull.

I see neither NewAppointment property in AppointmentCreatingEventArgs class nor BaseAppointmentCollection<IAppointment> in the RadScheduleView assembly.

What am I doing wrong?

Thanks,
Anatoly

Hello Anatoly,

In RadScheduleView it is a bit different.

1) Instead of using BaseAppointmentCollection<IAppointment> you could use plain ObservableCollection<CustomAppointment>. It is important to use your CustomAppointment class as generic parameter for the ObservableCollection in order to enable RadScheduleView to properly instantiate appointments of your class.

2) You should use the AppointmentCreated event to set properties on the newly created appointment through the Appointment property of the event args.

Hello Valeri,

I've tried your solution and got an exception when adding new appointment. It happens between AppointmentCreating and AppointmentCreated events.

The value "New Subject : 18.11.2010 0:00:00 - 25.11.2010 0:00:00" is not of type "MyWpfApplication.MyAppointment" and cannot be used in this generic collection.

   at System.ThrowHelper.ThrowWrongValueTypeArgumentException(Object value, Type targetType)
   at System.Collections.ObjectModel.Collection`1.System.Collections.IList.Add(Object value)
   at Telerik.Windows.Controls.ScheduleView.ScheduleViewDataConnection.HackCollectionViewBug(Boolean isCommit) in c:\Builds\WPF_Scrum\Release_WPF_2010_Q3\Sources\Development\Controls\ScheduleView\ScheduleView\Controls\ScheduleViewDataConnection.cs:line 887

MyAppointment is my custom appointment class. By the way, e.Appointment is of correct type MyAppointment on AppointmentCreating.

Could you please advise?

Regards,
Anatoly.

the same is happening with me

I solve the problem implementing copyfrom, copy.

Hello Everybody,

 As Nuno correctly noticed, it is very important to implement the Copy method, because it creates a new instance and we need this in various scenarios. In this case this should be enough to fix the problem.

I now have another problem. I want to change the style of AppointmentItem, but that the bindings to the propridades CostumAppoitment not work.

[nuno]

I know what it was. My properties must be defined as follows:

public string ClientCode

{

    get

    {

        return base.Storage<ServiceAppointment>().clientCode;

    }

    set

    {

        ServiceAppointment storage = base.Storage<ServiceAppointment>();

        if (storage.clientCode!= value)

        {

            storage.clientCode= value;

            this.OnPropertyChanged<string>(() => this.ClientCode);

        }

    }

}

[nuno]

Sorry but the solution is not complete, the binding dont work

<Setter Property="ContentTemplate">
   <Setter.Value>
       <DataTemplate>
           <TextBlock Text="{Binding Path=ClienteCode}" />
       </DataTemplate>
   </Setter.Value>
</Setter>

The binding dont work with ClienteCode but work with End, subject  etc....

Datacontext have a Appointment proxy, i need a CostumAppointment proxy  

[Miroslav Nedyalkov]

Hi Nuno,

 You could use the Appointment property of the proxy which is the actual appointment. We are currently working on overcoming this limitation.

I have the same problem. Working with custum appointments is more complex then neccessary. I suugest that your solution will offer een factory that can be injected in the ScheduleView. Product of the factory.Create will be a IAppointment.

Success

[Miroslav Nedyalkov]

Hi Cees,

 We don't need a factory as we use an EditableCollectionView which creates objects correctly. For more information about creating custom appointments you could refer the following blog post - http://blogs.telerik.com/blogs/posts/10-11-25/how_to_create_custom_appointments_and_custom_appointment_dialog_in_telerik_scheduleview.aspx.

Hope this helps!
