wpf calendar appears empty when displaymode is year or decade

i have a standard calendar control defined in my xaml file:

<Calendar Height="200" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,0,0,0"
Name="NewCalendarYear" Width="200" SelectedDatesChanged="NewCalendarYear_SelectedDatesChanged" DisplayMode="Decade" />

the problem I am having is that it works properly when DisplayMode="Month", but when changing it to "Year" or "Decade" the Calendar appears empty... with one arrow pointing to the left (i am not allowed to upload images). I have been searching but I have not found a sample of any xaml calendar code that works properly in these displaymodes.

Thanks¡¡

It´s the Year 2022 and within Net 6.0 this issue still exists...

With the previous answer and some research i have found a solution for me that works.

Unfortunately the Loaded- Event is not enough, if you like to keep the display Mode as it is set... (as microsoft tells Here ... YAY!^^)

Here is my Example Workaround in Codebehind. I have used DisplayMode "Year".

First i have assigned the Loaded- Event of the calendar control within XAML

View.xaml:

    <Calendar
       Loaded="Calendar_OnLoaded"
       Width="auto"
       DisplayDate="{x:Static sys:DateTime.Now}"
       />

Second the Codebehind Workaround

View.xaml.cs

// set Display Mode after calender is loaded for the first time and subscribe "DisplayModeChanged" Event
private void Calendar_OnLoaded(object sender, RoutedEventArgs e)
    {
        Calendar calObj = sender as Calendar;
        calObj.DisplayMode = CalendarMode.Year;
        calObj.DisplayModeChanged += new EventHandler<CalendarModeChangedEventArgs> (Calendar_DisplayModeChanged);
    }
// set Display Mode each time user has made a selection within calender
private void Calendar_DisplayModeChanged(object sender,
                                         CalendarModeChangedEventArgs e)
    {
        Calendar calObj = sender as Calendar;

        calObj.DisplayMode = CalendarMode.Year;
    }

I was having the same issue.

There's some kind of bug with setting the DisplayMode in XAML. If you set it in the codebehind, on the _Load event, it will work!
