在组件外部单击后,日历鼠标左按钮向下被触发

我想通过单击日历控件中的日期,使用MouseLeftButtonDown引发事件。但是,在单击该组件外部之前,它不会被提起。
这是xaml代码:
<Controls:BasicCalendar Grid.Row="0"
x:Name="DemoCalendar"
DisplayDate="{Binding Path=DisplayDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
HighlightedDateText="{Binding HighlightedDateText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Grid.Column="0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Margin="0,0,0,0"
DateHighlightBrush="Gold">
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseLeftButtonDown">
<cal:ActionMessage MethodName="CalendarSelectDateEvent">
<cal:Parameter Value="{Binding ElementName=DemoCalendar, Path=SelectedDate}" />
</cal:ActionMessage>
</i:EventTrigger>
</i:Interaction.Triggers>
</Controls:BasicCalendar>
以下是我想在点击日历中的某个日期后提出的事件:
public void CalendarSelectDateEvent(DateTime selectedDate)
{
this.ActualCalendarEvents = this.CalendarEvents.Where(x => x.Date >= selectedDate).ToList();
var a = this.ActualCalendarEvents;
this.ActualCalendarEvents = null;
NotifyOfPropertyChange(() => ActualCalendarEvents);
this.ActualCalendarEvents = a;
NotifyOfPropertyChange(() => ActualCalendarEvents);
}
当我尝试使用Click事件而不是MouseLeftButtonDown时,日历控件会自动处理它,而不会触发CalendarSelectDateEvent。有没有办法取消这两项活动?(对于日历控件,选择并突出显示日期,对于我,CalendarSelectDateEvent)
我已经想好了。最后真的很容易。日历控件具有SelectedDate属性。我刚刚在代码隐藏中将SelectedDate绑定到我的属性SelectedDateChanged,当SelectedDate更改时,我引发事件CalendarSelectDateEvent。
<Controls:BasicCalendar Grid.Row="0"
x:Name="DemoCalendar"
DisplayDate="{Binding Path=DisplayDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
HighlightedDateText="{Binding HighlightedDateText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Grid.Column="0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Margin="0,0,0,0"
SelectedDate="{Binding SelectedDateChanged}"
DateHighlightBrush="Gold">
</Controls:BasicCalendar>
像这样:
public DateTime SelectedDateChanged
{
get
{
return selectedDateChanged;
}
set
{
this.selectedDateChanged = value;
this.CalendarSelectDateEvent(this.selectedDateChanged);
}
}
