我使用 WPF 工具包创建了一个 12 个月的日历。我花了一段时间才达到这一点，日历是透明的，文本前景看起来正确。
当我更改 CalendarDayButtonStyle 的样式时，我得到了正确的前景色，但我完全失去了我选择的日期，我不确定缺少什么或不正确。
下面是 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。在这一点上，我需要解决的只是让我选择的日子再次突出显示。我不知道缺少什么，因为我已经尝试了所有内容。
谢谢
