how to use bingding property in the ScheduleView ConrolTemplate

[Yi]

i add the SchuleView Theme to my project.
and the controlTemple Binding like:

<telerik:RadComboBox x:Name="PART_TimeMarkers"

                                         Margin="2 1"

                                         Width="110"

                                         IsEnabled="{Binding IsReadOnly, Converter={StaticResource InvertedBooleanConverter}}"

                                         ClearSelectionButtonVisibility="Visible"

                                         ClearSelectionButtonContent="Clear All"

                                         EmptyText="TimeMarkers
"

                                         ItemsSource="{Binding TimeMarkers}"

                                         SelectedItem="{Binding Occurrence.Appointment.TimeMarker, Mode=TwoWay}"

                                         ItemTemplate="{StaticResource TimeMarkerComboBoxItemContentTemplate}"

                                         SelectionBoxTemplate="{StaticResource TimeMarkerComboBoxItemContentTemplate}"

                                         telerik:StyleManager.Theme="{StaticResource Theme}"/>

for example: i follow the demo project,and binding the ItemsSource successfully. but how can i make the RadComboBox has default value? set the SelectedIndex seems to not use. and how to binding IsEnabled property.which palace i can set the value. and how to ClearSelectionButtonContent Property to localization? 
sorry that i am a fresher.

Hello Yi,

Straight to your questions - in order to have a default TimeMarker selected when the EditAppointmentDialog is open you could use the ShowDialog event. Inside of the handler you can reach the AppointmentDialogViewModel with the TimeMarker collection and set one of them as default to the new Appointment.

The IsReadOnly property is used in many places in the EditAppointmentDialog, that's why changing its value will disable the whole EditAppointmentDialog. However you could use the AdditionalData property which is used only for adding a custom logic and then also in the ShowDialog event handler you can change it true or false depending of the requirement.

As for the last question the ClearSelectionButtonContent is localized by default, so you don't need to do anything extra just keep the default binding.

IsEnabled and ClearSelectionButtonContent should look like follows:

IsEnabled="{Binding AdditionalData, Converter={StaticResource InvertedBooleanConverter}}"
ClearSelectionButtonContent="{Binding ClearSelectionButtonContent}"

The ShowDialog event handler should look like below:

private void scheduleView_ShowDialog(object sender, ShowDialogEventArgs e)
{
    if (e.DialogViewModel is AppointmentDialogViewModel)
    {
        var dialogVM = e.DialogViewModel as AppointmentDialogViewModel;
        var appointment = dialogVM.Occurrence.Appointment as Appointment;
        if (appointment != null)
        {
            appointment.TimeMarker = dialogVM.TimeMarkers.First();
            dialogVM.AdditionalData = true;
        }
    }
}

Hope this works for you.
