我想在我的地铁应用程序中使用 DATEPICKER 控件，但似乎在 C#/XAML 地铁应用程序中没有可用的日期选择器控件，
那么你们中有没有人找到解决方法？
请让我知道，
谢谢和问候。
我从 codeplex 上的一个私有解决方案中找到了这一点，我真诚地向拥有该链接的人道歉......但您可以使用以下代码创建控件：
Xaml 文件：
<UserControl x:Class="MyNamespace.Controls.DatePicker"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<ComboBox x:Name="Day" Grid.Column="0" SelectionChanged="Day_SelectionChanged" Width="70" Margin="0,0,10,0" />
<ComboBox x:Name="Month" Grid.Column="1" SelectionChanged="Day_SelectionChanged" Width="70" Margin="0,0,10,0" />
<ComboBox x:Name="Year" Grid.Column="2" SelectionChanged="Day_SelectionChanged" Width="100" />
</Grid>
</Grid>
</UserControl>
它背后的代码是：
using System;
using System.Collections.Generic;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
namespace MyNamespace.Controls
{
public sealed partial class DatePicker
{
private bool initializing = true;
public DatePicker()
{
InitializeComponent();
UpdateValues(0, 0);
Day.SelectedIndex = 0;
Month.SelectedIndex = 0;
Year.SelectedIndex = 0;
initializing = false;
}
public static readonly DependencyProperty AllowNullProperty =
DependencyProperty.Register("AllowNull", typeof(bool), typeof(DatePicker), new PropertyMetadata(true));
public bool AllowNull
{
get { return (bool)GetValue(AllowNullProperty); }
set { SetValue(AllowNullProperty, value); }
}
public static readonly DependencyProperty SelectedDateProperty =
DependencyProperty.Register("SelectedDate", typeof(DateTime?), typeof(DatePicker), new PropertyMetadata(null, OnSelectedItemChanged));
public DateTime? SelectedDate
{
get { return (DateTime?)GetValue(SelectedDateProperty); }
set { SetValue(SelectedDateProperty, value); }
}
public event RoutedEventHandler SelectedItemChanged;
private static void OnSelectedItemChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var ctrl = (DatePicker)d;
if (ctrl.initializing)
return;
ctrl.initializing = true;
ctrl.UpdateDate();
ctrl.initializing = false;
if (ctrl.SelectedItemChanged != null)
ctrl.SelectedItemChanged(ctrl, new RoutedEventArgs());
}
public void UpdateDate()
{
if (SelectedDate.HasValue)
{
UpdateValues(SelectedDate.Value.Year, SelectedDate.Value.Month);
if (AllowNull)
{
Day.SelectedIndex = SelectedDate.Value.Day;
Month.SelectedIndex = SelectedDate.Value.Month;
Year.SelectedIndex = SelectedDate.Value.Year - 2000 + 1;
}
else
{
Day.SelectedIndex = SelectedDate.Value.Day - 1;
Month.SelectedIndex = SelectedDate.Value.Month - 1;
Year.SelectedIndex = SelectedDate.Value.Year - 2000;
}
}
else
{
UpdateValues(0, 0);
Day.SelectedIndex = 0;
Month.SelectedIndex = 0;
Year.SelectedIndex = 0;
}
}
public void UpdateValues(int year, int month)
{
var days = new List<string>();
if (AllowNull)
days.Add(" ");
for (var i = 1; i <= 31; i++)//(year != 0 && month != 0 ? DateTime.DaysInMonth(year, month) : 31); i++)
days.Add(i.ToString());
var months = new List<string>();
if (AllowNull)
months.Add(" ");
for (var i = 1; i <= 12; i++)
months.Add(i.ToString());
var years = new List<string>();
if (AllowNull)
years.Add(" ");
for (var i = 2000; i <= 2020; i++)
years.Add(i.ToString());
if (Month.SelectedIndex > months.Count - 1)
Month.SelectedIndex = months.Count - 1;
Day.ItemsSource = days;
Month.ItemsSource = months;
Year.ItemsSource = years;
}
private void Day_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (initializing)
return;
var hour = SelectedDate != null ? SelectedDate.Value.Hour : 0;
var minute = SelectedDate != null ? SelectedDate.Value.Minute : 0;
var second = SelectedDate != null ? SelectedDate.Value.Second : 0;
initializing = true;
if (AllowNull && (Day.SelectedIndex == 0 || Month.SelectedIndex == 0 || Year.SelectedIndex == 0))
SelectedDate = null;
else
{
if (AllowNull)
SelectedDate = new DateTime(Year.SelectedIndex + 2000 - 1, Month.SelectedIndex, Day.SelectedIndex, hour, minute, second);
else
SelectedDate = new DateTime(Year.SelectedIndex + 2000, Month.SelectedIndex + 1, Day.SelectedIndex + 1, hour, minute, second);
}
//if (SelectedItem.HasValue)
// UpdateValues(SelectedItem.Value.Year, SelectedItem.Value.Month);
//else
// UpdateValues(0, 0);
initializing = false;
}
}
}
现在有一个由Microsoft提供的用于windwos store应用程序的DatePicker控件。它随Windows 8.1一起提供。
在此处查看其他新控件：http://msdn.microsoft.com/en-us/library/windows/apps/bg182878.aspx
Telerik 有一个 DatePicker。但它不是免费的。
通过此链接，我认为这就是您正在寻找的。
在此之前，您应该必须安装免费 telerik windows8 rc
