WPF Datepicker - Bolded Dates

Is there any way to set a series of dates that will be displayed within the DatePicker as bold (or otherwise highlighted)?

=UPDATE= Apologies, seems I have not explained myself sufficiently. I am looking to get outlook-similar behaviour with the calendar popup on the WPF DatePicker. An example is as follows;

All dates are still selectable and the bolded dates are shown irrespective of any current selection. The purpose of these bolded dates are to aid the user in sele开发者_如何转开发cting a date and or to represent items of interest.

Will crossing out work? if so, you could use BlackoutDates (you can have multiple CalendarDateRange )

<DatePicker.BlackoutDates>
    <CalendarDateRange Start="2/1/2011" End="2/10/2011"/>
</ DatePicker.BlackoutDates>

or from code

calendar1.BlackoutDates.Add(new CalendarDateRange(
        new DateTime(2011, 2, 1),
        new DateTime(2010, 2, 10)
        ));

You can select multiple dates like this

<DatePicker Name="MonthlyCalendar"    
    SelectionMode="MultipleRange"     
    DisplayDate="3/5/2010"    
    DisplayDateStart="3/1/2010"    
    DisplayDateEnd="3/31/2010"    
    FirstDayOfWeek="Tuesday"    
    IsTodayHighlighted="True"    
    xmlns:sys="clr-namespace:System;assembly=mscorlib" Margin="15,39,88,19">
    <DatePicker.SelectedDates>    
        <sys:DateTime>3/5/2010</sys:DateTime>    
        <sys:DateTime>3/15/2010</sys:DateTime>    
        <sys:DateTime>3/25/2010</sys:DateTime>    
     </DatePicker.SelectedDates> 
</DatePicker>
