Combobox/Custom Field in Edit Appointment Dialog

[Tim]

I have custom fields in my Appointment Dialog. I want to change one of the TextBoxes to a ComboBox.

Here is the section I want to modify that is currently in my Telerik.Windows.Controls.ScheduleView.xaml

<TextBlock Grid.Row="7" Grid.Column="0" Margin="6" VerticalAlignment="Center" telerik:LocalizationManager.ResourceKey="Reason for reschedule" />
<TextBox Grid.Row="7" Grid.Column="1" Grid.ColumnSpan="2" Margin="3" IsReadOnly="{Binding IsReadOnly}" Text="{Binding Occurrence.Appointment.RescheduleReason, ValidatesOnDataErrors=True, NotifyOnValidationError=True, Mode=TwoWay}" telerik:StyleManager.Theme="{StaticResource Theme}" />

I want to replace the second textbox with the following:

<ComboBox Grid.Row="7" Grid.Column="1" Grid.ColumnSpan="2" Margin="3" ItemsSource="{Binding }"

I want to bind the ItemsSource to an ObservableCollection available in my View Model page. I then want to bind the selected item to Occurrence.Appointment.RescheduleReason much like the current textbox's text is bound to.

I am having issues accessing the ObservableCollection CancelReasons though. It is set up in my ViewModel as:

private ObservableCollection<OptionSet> cancelReasons;
public ObservableCollection<OptionSet> CancelReasons
{
get
{
return this.cancelReasons;
}
private set
{
this.cancelReasons = value;
this.OnPropertyChanged("CancelReasons");
}
}

How can I accomplish this?

Here is a bit more information:

This is where I am populating my ObservableCollection

public MainPageViewModel(ILifestyleLiftServiceAgent serviceAgent)
{
MscrmSrvc.Service1Client proxy = new Scheduler.MscrmSrvc.Service1Client();
proxy.GetOptionSetCompleted += new EventHandler<MscrmSrvc.GetOptionSetCompletedEventArgs>(proxy_GetOptionSetCompleted);
proxy.GetOptionSetAsync("", "myOptionSet");
}

void proxy_GetOptionSetCompleted(object sender, MscrmSrvc.GetOptionSetCompletedEventArgs e)
{
   ObservableCollection<Dictionary<string,string>> myList = e.Result;
   ObservableCollection<OptionSet> myOptionSet = new ObservableCollection<OptionSet>();

   foreach (Dictionary<string, string> myItem in myList)
   {
      foreach (KeyValuePair<string, string> kvp in myItem)
      {
         OptionSet os = new OptionSet();
         os.Label = kvp.Key;
         os.Value = kvp.Value;

         myOptionSet.Add(os);
      }
   }

   CancelReasons = myOptionSet;
}

My ScheduleView.xaml has this line added to it:

<ComboBox Grid.Row="7" Grid.Column="1" Grid.ColumnSpan="2" Margin="3" ItemsSource="{Binding CancelReasons}" />

When I bring up the Appointment dialog, the combobox is empty. It should contain 1 item as I've verfied proxy_GetOptionSetCompleted is called correctly and populates the CancelReasons ObservableCollection.

Thanks

I have further changed my combobox to the following:

<telerik:RadComboBox Grid.Row="7" Grid.Column="1" Grid.ColumnSpan="2" Margin="3" ItemsSource="{Binding ElementName=radScheduleView, Path=DataContext.CancelReasons, Mode=TwoWay}" DisplayMemberPath="Label"  />

Where:

<telerik:RadScheduleView telerik:StyleManager.Theme="Office_Silver" x:Name="radScheduleView"
                                        Grid.Column="0" Grid.Row="0"

And my CancelReasons is an ObservableCollection of OptionSet:

public class OptionSet
    {
        public OptionSet()
        {

        }

        public OptionSet(string label, string value)
        {
            this.Label = label;
            this.Value = value;
        }

        public string Label { get; set; }
        public string Value { get; set; }
    }

The combobox is still coming up empty even though I see one entry in the CancelReasons.

Any ideas from here?

I would kindly ask you not to post the same question in different threads as this slows our reply.
