AppointmentsSource not showing in the control

[Christie Admin]

Hi,

I use a WeekView definition, I set the FirstDayOfWeek to Monday and the VisibleDays to 5 to see only Monday to Friday. I add 5 appointments, 1 for each day of the week. If my computer datetime is different than Sunday, all my appointments are visible in the control. If my computer datetime is on Sunday, no one are visible in the control!!!

Thank's
Alain

Hi,

I suggest you check whether the generated appoinments dates are in the visible range of RadScheduleView.

If this does not help and the problem continues to persist,  please send us your code to review it and give you more instructions.

Ho Rosi,

just try it with your online demo. Set your computer date to a sunday and try using the weekviewdefinition. Setting your computer to any other week day cause the demo to display the appointments but when you set it to a sunday, nothing are visible.

Thank's

Hi Alain,

I tried to reproduce the explained issue but not avail. I tested it in our online Silverlight demos - with the Appointment Template example. I'm attaching a video which shows my test - check it and let me know if I'm missing anything here.

I'm looking forward to your response

Hi Kalin,

I can reproduce it easily with your WPF online demo... Set your computer to a sunday, go in the FirstLook example of the scheduleview control, click on the week view definition. Nothing was shown... Go on an another control, set your computer date to any other day than a sunday, go back on the first look example of the scheduleview, click on the week view definition button, now you can see data.

Hi Alain,

I successfully managed to reproduce the described issue. After further investigation appears that the LoadAppointmentsSource is not calculating correctly the the first day of the week and when is Sunday it moves the Appointments to the next week. However we will fix the demo as soon as possible, for now you can use the modified method below:

protected static IEnumerable<T> LoadAppointmentsSource(Uri appointmentsSource)
{
    if (appointmentsSource != null)
    {
#if WPF
        IEnumerable<T> appointments = Application.LoadComponent(appointmentsSource) as IEnumerable<T>;
#else
        string text = new System.IO.StreamReader(Application.GetResourceStream(appointmentsSource).Stream).ReadToEnd();
        ObservableCollection<T> appointments = System.Windows.Markup.XamlReader.Load(text) as ObservableCollection<T>;
#endif
        DateTime firstDate = appointments.Min(new Func<T, DateTime>(GetStart));
        DayOfWeek firstDay = CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek;

        var dayDifference = (int)DateTime.Today.DayOfWeek - (int)firstDay;
        dayDifference = dayDifference >= 0 ? dayDifference : DateTimeFormatInfo.CurrentInfo.DayNames.Length + dayDifference;

        DateTime firstDayOfCurrentWeek = DateTime.Today.Subtract(TimeSpan.FromDays(dayDifference));
        TimeSpan offset = firstDayOfCurrentWeek - firstDate;
        foreach (IAppointment appointment in appointments)
        {
            appointment.Start += offset;
            appointment.End += offset;
        }

        return appointments;
    }

    return Enumerable.Empty<T>();
}

Hope this helps. I have also updated you Telerik points for the involvement.

Hi Kalin,

where should I use the provided protected method???

Thank's
Alain

Hi Alain,

I'm sorry for the misunderstanding, I thought you are using the same approach in your application as the one used in the demo. The mentioned method is located in the ExampleViewModel.cs file of the online example and it is causing the explained issue. If you are not using the same approach you shouldn't have the issue present. So if your case is different I'll ask you to provide us with more details on the ScheduleView implementation, sharing some sample code would be really helpful.

I'm looking forward to your reply.

Hi Kalin,

no, I refered to the demo just as a reference. I use a collection of object and I assign it to the AppointmensSouce member of the control.

Thank's

Hello Alain,

We are not able to reproduce the described issue outside of the example. What I'm going to ask you is to open a support ticket with a sample project attached and also include information about the used version of the controls, so we can reproduce the issue on our side.

Hope this helps.

Hi Kalin,

you just have to set the date of your pc on a sunday and add a collection of objects to the AppointmentsSource of the ScheduleView. Nothing should be visible in the ScheduleView... The same pattern work well if the date of your pc is set on any other day than a sunday.

Thank's

Hello Alain,

Your ticket came to my attention as it looks like there is some kind of confusion or misunderstanding. I've read all of the messages and I would like to clarify the problem and what could be causing it. Your explanation seems clear enough and as a matter of fact I've tried to reproduce the issue, but without success. I'm sending you my test project and a short video showing my steps. Could you take a look at them - maybe I've missed something? If you are able to reproduce the issue with the project I've sent you, could you give us more details for the exact version of Telerik UI for WPF that you are using and the Culture that's set on your machine.

If the issue is not reproducible with the attached project, could you modify it and send it back to us, so we'll be able to investigate it further. We'll be glad to assist you further, but we'll need more information on your scenario.

I'm looking forward to hearing from you.

Hello Alain,

It looks like there is a problem in the referenced assemblies - could you verify that all of them are the same version? It looks like one of them is from 2013.3.1204.40 version, while the others are not.

Hope this helps.
