Hello David,

In the current version of RadCalendar it is not possible bind the SelectedDates to a Collection of DateTime objects. The SelectedDates property has only a Get method in order to get the selected dates in the control but it cannot be used to bind a collection to the control.

If you have any other questions do not hesitate to contact us again.

I have been playing with a workaround for this limitation. 

I use a trigger on SelectionChanged: 
            <inter:Interaction.Triggers>
                <inter:EventTrigger EventName="SelectionChanged">
                    <galaSoftMvvmLightCommand:EventToCommand PassEventArgsToCommand="True" Command="{Binding ChangeCalendarSelectionCommand}" CommandParameter="{Binding SelectedDates, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadCalendar}}}" />
                </inter:EventTrigger>
            </inter:Interaction.Triggers>

which binds to a Relaycommand, and passes in an ObservableCollection<DateTime> as command parameters. Problem to overcome then is that it fires multiple times so shouldn't be used for long running task.
