检测何时在Silverlight日历控件上单击一天

您可以通过将day按钮的ClickMode设置为“Hover”来实现这一点。 在这之后,你可以进入MouseLeftButtonDown事件

    <sdk:Calendar Name="calendar1" MouseLeftButtonDown="calendar1_MouseLeftButtonDown">
        <sdk:Calendar.CalendarDayButtonStyle>
            <Style TargetType="Primitives:CalendarDayButton">
                <Setter Property="ClickMode" Value="Hover"/>
            </Style>
        </sdk:Calendar.CalendarDayButtonStyle>
    </sdk:Calendar>

不是很干净的解决方案。此外,它也没有正确地考虑到BlackoutDates,因为按钮的IsBlackOut属性也是内部的。我可以在click事件中手动检查它,但出于我的目的,我不需要支持它。

void CalendarControl_Loaded(object sender, RoutedEventArgs e)
{
    var grid = FindVisualChildByName<Grid>(CalendarControl, "MonthView");
    // Loaded may be called several times before both the grid and day buttons are created
    if (grid != null && grid.Children.OfType<System.Windows.Controls.Primitives.CalendarDayButton>().Any()) 
    {
        // Add our own click event directly to the button
        foreach (var button in grid.Children.OfType<System.Windows.Controls.Primitives.CalendarDayButton>().Cast<System.Windows.Controls.Primitives.CalendarDayButton>())
        {
            button.Click += new RoutedEventHandler(button_Click);
        }
        // We only want to add the event once
        CalendarControl.Loaded -= new RoutedEventHandler(CalendarControl_Loaded);
    }
}

void button_Click(object sender, RoutedEventArgs e)
{
    var button = (System.Windows.Controls.Primitives.CalendarDayButton)sender;
    var date = button.DataContext as DateTime?;
    // The user clicked a date. Close the calendar and do something with it
}
