失去了更改WPF工具包日历所选日期颜色的能力

Question

我使用WPF工具包创建了一个12个月的日历。我花了一段时间才到达这一点，日历是透明的，文本前景看起来是正确的。

当我更改CalendarDayButtonStyle的样式时，我得到了正确的前景颜色，但我完全丢失了我选择的日期，我不确定缺少什么或不正确。

以下是XAML

<toolkit:Calendar CalendarItemStyle="{DynamicResource calItemStyle}" CalendarDayButtonStyle="{DynamicResource styleCalDayBtn}" Name="calJan" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" HorizontalAlignment="Center" VerticalAlignment="Center" MouseDoubleClick="DateSelect_Jan_DoubleClick" SelectedDatesChanged="calJan_SelectDateChanged" SelectionMode="MultipleRange" />

这是styleCalDayBtn。此时我需要解决的是，再次突出显示我选择的日期。我不知道什么是遗漏，因为我已经尝试过所有东西。

由于
