AppointmentTemplate is not working properly

[palak]

Dear telerik,

I've a one dropdown(out of scheduleview) for localization and in that dropdown there are different languages option available.
I've made one AppointmentTemplate which is like below:

<DataTemplate x:Key="AppointmentTemplate">
           <Grid>
               <Grid.RowDefinitions>
                   <RowDefinition Height="Auto"/>
                   <RowDefinition Height="Auto"/>
                   <RowDefinition Height="Auto"/>
                   <RowDefinition Height="*"/>

               </Grid.RowDefinitions>
               <TextBlock Grid.Row="0" Text="{Binding Appointment.Resources[1].ResourceName}"
                          HorizontalAlignment="Left"
                          VerticalAlignment="Top" FontSize="13" Foreground="Black" FontWeight="Bold" />
               <TextBlock Grid.Row="1" Text="{Binding Appointment.Subject}"
                          HorizontalAlignment="Left"
                          VerticalAlignment="Top" FontSize="9" Foreground="Black" FontWeight="Bold"/>
               <TextBlock Grid.Row="2" Text="{Binding Appointment.Body}"
                          HorizontalAlignment="Left"
                          VerticalAlignment="Top" FontSize="9" Foreground="Black" FontWeight="Bold" />
               <TextBlock Grid.Row="3" Text="{Binding Appointment.Start}"
                          HorizontalAlignment="Left"
                          VerticalAlignment="Top" FontSize="9" Foreground="Black" FontWeight="Bold"/>
           </Grid>
       </DataTemplate>

Now i assign this template in RadScheduleview like below:

AppointmentItemContentTemplate="{StaticResource AppointmentTemplate}"

My problem is like, whenever i change language from my dropdown, appointment item template works strange way.
Like there is 5 language ,i randomly change language(spanish,french,turkis etc.), and appointment template items getting hidden means some shows up(resourcename only), some gone(subject,body etc.) , sometimes it shows all items in appointment template, sometimes for the same option(like spanish or turkish etc.), few items gone. sometimes for some apointments(random in current view), appointment template shows up all items, for some appointments, some items gone.

I mean to say, appointment template is working partially, not seamlessly.

kindly check, if you need, i'll give u sample.

thanks & regards

Hello,

One of the problems I have found is that the binding to 'Appointment.Resources[1]' would sometimes bind to one resource type sometimes to other. There is no definition about which resource will get first in the appointment and which second so having the ScheduleView grouped by both Rooms and Speaker and moving the appointments around would sometimes show room number, sometimes speaker name.

As for the Subject and Body I have failed to reproduce the problem. Could you give me the code that actually execute when you change the selection from your dropdown and change the localization? I wish to further test that issue.

hi pana,

I agree about your opinion regarding 'Appointment.Resources[1]' as i had to intentionally set this workaround because i was not able to point out by resource name or another way(in .xaml and .xaml.cs both, if you have solution , share with us). While dragging or dropping or any operations, i am reloading my appointments quickly after, so it gets right value for appointment template.
My problem is appointment template always have all values, but some goes, some comes up, sometimes all shows up for some appointments but not for some appointments.

As i am working with sharepoint 2010, it would be timeconsuming for you to reproduce the problem if i'll give u solution directly. so here is a sample code related to my problem. ask me if anything still needed even project also.

here is localization dropdown code :

private void AvailableCulturesComboBox_SelectionChanged(object sender, EventArgs e)
 {
     LocalizationManager.DefaultCulture = (CultureInfo)(sender as Telerik.Windows.Controls.RadComboBox).SelectedItem;
     //LocalizationManager.DefaultCulture = (CultureInfo)AvailableCulturesComboBox.SelectedItem;
     //this.SchedulerView.AppointmentItemContentTemplate.LoadContent();
     Dispatcher.BeginInvoke(ResetTemplate);
 }

 public static List<CultureInfo> SupportedCultures
 {
     get
     {
         if (_SupportedCultures == null)
         {
             _SupportedCultures = new List<CultureInfo>();
             _SupportedCultures.Add(CultureInfo.InvariantCulture);
             _SupportedCultures.Add(new CultureInfo("en-us"));
             _SupportedCultures.Add(new CultureInfo("hi-IN"));
             _SupportedCultures.Add(new CultureInfo("es"));
             _SupportedCultures.Add(new CultureInfo("de"));
             _SupportedCultures.Add(new CultureInfo("tr"));
             _SupportedCultures.Add(new CultureInfo("it"));
             _SupportedCultures.Add(new CultureInfo("nl"));
         }

         return _SupportedCultures;
     }
 }

 private void ResetTemplate()
 {
     ControlTemplate template = this.SchedulerView.Template;
     this.SchedulerView.Template = null;
     this.SchedulerView.Template = template;
 }

Here is my custom appointment Class :

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Telerik.Windows.Controls.ScheduleView;

namespace HaiderSchedulerView
{
    public class ResourceAppointment : Appointment
    {
        #region Members & properties

        private int _AppointmentId;
        private string _CreatedBy;
        private string _ModifiedBy;

        public int AppointmentId
        {
            get
            {
                return this.Storage<ResourceAppointment>()._AppointmentId;
            }
            set
            {
                var storage = this.Storage<ResourceAppointment>();
                if (storage._AppointmentId != value)
                {
                    this._AppointmentId = value;
                    this.OnPropertyChanged(() => this.AppointmentId);
                }
            }
        }

        public string CreatedBy
        {
            get
            {
                return this.Storage<ResourceAppointment>()._CreatedBy;
            }
            set
            {
                var storage = this.Storage<ResourceAppointment>();
                if (storage._CreatedBy != value)
                {
                    this._CreatedBy = value;
                    this.OnPropertyChanged(() => this.CreatedBy);
                }
            }
        }

        public string ModifiedBy
        {
            get
            {
                return this.Storage<ResourceAppointment>()._ModifiedBy;
            }
            set
            {
                var storage = this.Storage<ResourceAppointment>();
                if (storage._ModifiedBy != value)
                {
                    this._ModifiedBy = value;
                    this.OnPropertyChanged(() => this.ModifiedBy);
                }
            }
        }

        #endregion

        public override IAppointment Copy()
        {
            var appointment = new ResourceAppointment();
            appointment.CopyFrom(this);
            return appointment;
        }
        public override void CopyFrom(IAppointment other)
        {

            var appointment = other as ResourceAppointment;
            if (appointment != null)
            {
                this.AppointmentId = appointment.AppointmentId;
                this.Subject = appointment.Subject;
                this.Start = appointment.Start;
                this.End = appointment.End;
                this.Body = appointment.Body;
                this.CreatedBy = appointment.CreatedBy;
                this.ModifiedBy = appointment.ModifiedBy;
            }
             base.CopyFrom(other);
        }
    }
}

Resources , Rooms, and appointments are binding dynamically.
First Rooms are getting bound, then resources, and then appointments getting bound , sequentially.
