银灯DatePicker YearMonth和年份

Question

我需要一个Silverlight DatePicker控件，它允许用户只选择一年或选择YearMonth。允许我在xaml中设置这类功能，如下所示：

<sdk:DatePicker my:DatePickerCalendar.IsYear="True" my:DatePickerFormat="yyyy"/>

或

<sdk:DatePicker my:DatePickerCalendar.IsMonthYear="True" my:DatePickerFormat="MM/yyyy"/>

Answer 1

我找到的最简单的解决方案是

DateTimePicker年开始

private void dp_CalendarOpened(object sender, RoutedEventArgs e)
    {
        DatePicker dp = (DatePicker)sender;
        Popup popup = (Popup)dp.Template.FindName("PART_Popup", dp);
        Calendar cal = (Calendar)popup.Child;

        cal.DisplayMode = CalendarMode.Year;
        cal.DisplayModeChanged += cal_DisplayModeChanged;
    }

private void cal_DisplayModeChanged(object sender, CalendarModeChangedEventArgs e)
    {
        Calendar calendar = (Calendar)sender;
        Popup popup = (Popup)calendar.Parent;

        if (e.NewMode == CalendarMode.Month)
        {
            //calendar.DisplayMode = e.OldMode;
            calendar.SelectedDate = calendar.DisplayDate.AddDays((calendar.DisplayDate.Day * -1) + 1).AddMonths(1).AddDays(-1);
            popup.IsOpen = false;

            calendar.DisplayModeChanged -= cal_DisplayModeChanged;
        }
    }

Answer 2

您可以尝试此修改后的silverlight日期选择控件仅显示月份或年份。

<sdk:DatePicker Name="datepicker1"
                Height="23"
                Width="150"
                SelectedDateFormat="MonthYear"
                CalendarMode="Year" />

DatePicker月或年
