MinDate/MaxDate not respected

[Michael Pillwax]

We have implemented the CalendarEdit control in this way, but the MinDate/MaxDate are not respected when the control is shown: Dates beyond MinDate/MaxDate are shown and selectable:

<sf:CalendarEdit x:Name="PopupKernFormStatusCalendar"
 Date="{Binding Mode=OneWay, Path=DataContext.AssociatedObjectDataContext.CalendarMaxDate, RelativeSource={RelativeSource AncestorType={x:Type Popup}}}"
 MinDate="{Binding Mode=OneWay, Path=DataContext.AssociatedObjectDataContext.CalendarMinDate, RelativeSource={RelativeSource AncestorType={x:Type Popup}}}"
 MaxDate="{Binding Mode=OneWay, Path=DataContext.AssociatedObjectDataContext.CalendarMaxDate, RelativeSource={RelativeSource AncestorType={x:Type Popup}}}"
 MinMaxHidden="True" IsShowWeekNumbers="True" ScrollToDateEnabled="True" VisualMode="Days" Margin="5 0 5 0"/>

The MinDate/MaxDate properties are read from the ViewModel correctly when the control shows, but all dates are shown and selectable:

/// <summary>
/// Min/Max dates for popup calendar
/// </summary>
public DateTime CalendarMinDate
{
get => DateTime.Today.AddMonths(-3);
}
public DateTime CalendarMaxDate
{
get => DateTime.Today;
}

What are we having here that the MinDate/MaxDate properties are not respected? The culture used is "de-DE".

Thanks for your support.

Hello,

attached is the sample application that replicates the issue we are having. From preparing it we learned the following:

1. The issue may be related to using a DataTemplate for the Popup, where the Calendar is used.
   
2. It may also be related to a data binding issue when using the Calendar Min/Max Date properties with a binding in the DataTemplate, although the Date property is working properly with binding.

The attached code replicated the issue here with us exactly as in our application.

Thanks for looking into this.
