如何改变事故发生日期?
原标题:How to change DatePicker default level ?

当使用银灯DatePicker时,它每天都在发生违约情况。 当用户必须选择其出生日时,如果他能够首先选择一年,并在不首先上树木的情况下立即进行钻井,那将是非常方便用户的。 我可以猜测,我们约70%的用户甚至 how不出如何利用日历头盔来达到顶峰,因此,如果我可以避免,那将是热爱的。

是否有办法操纵在违约时开标的日期?

在银星,是否对选择生育日有更方便用户的控制?

最佳回答

面对这一点,你应该能够做这样的事情:

        <sdk:DatePicker Name="datePicker1" >
            <sdk:DatePicker.CalendarStyle>
                <Style TargetType="sdk:Calendar">
                    <Setter Property="DisplayMode" Value="Decade" />
                </Style>
            </sdk:DatePicker.CalendarStyle>
        </sdk:DatePicker>

降幅中显示的日历上的其他许多特点都会发挥作用。 但是,每当开标时,数据小组的内部代码将设置<条码>DisplayMode至<条码>。 因此,我们需要诉诸一种ug:-

private void datePicker1_CalendarOpened(object sender, RoutedEventArgs e)
{

    DatePicker picker = (DatePicker)sender;

    if (!picker.SelectedDate.HasValue)
    {
        var popup = picker.Descendents().OfType<Popup>().FirstOrDefault();
        if (popup != null)
        {
            var item = popup.Child.Descendents().OfType<Calendar>().FirstOrDefault();
            if (item != null)
                item.DisplayMode = CalendarMode.Decade;
        }
    }
}

answer,供我执行Descendents 推广方法。
