Hi,

i have a custom appointment and i'm not able to bind a combobox inside the EditAppointmentDialog.
I saw already a topic there about this problem : http://www.telerik.com/community/forums/silverlight/scheduleview/add-combobox-in-appointmentdialog.aspx but it doesn't work for me.

Here the xaml for my silverlight page :

Note that it doesn't work for the combobox inside the EditAppointmentdialog : cmbProjects
but it works with the same binding formula
ItemsSource="{Binding ElementName=RecurrentScheduleView, Path=DataContext.Projets, Mode=TwoWay}"

if the combobox is outside the RadScheduleView : cmbProjects2

thanks by advance !

Hello Maxence,

The first way to resolve this is to bind your RadComboBox directly to the ViewModel:
<telerik:RadComboBox x:Name="cmbProjects" ItemsSource="{Binding Source={StaticResource ViewModel}, Path=Projets, Mode=TwoWay}"/>
As I can see your page is inheriting its DataContext. If you cannot access your ViewMiodel I would suggest you a workaround. You can attach to the Loaded event of your RadComboBox and load its items there:
private void cmbProjects_Loaded(object sender, RoutedEventArgs e)
{
    var viewModel = (ViewModel)this.RecurrentScheduleView.DataContext;
    var radComboBox = (RadComboBox)sender;
    radComboBox.Items.AddRange(viewModel.Projets);
}

Hope this helps.
