如何在警报和放大器中制作一个CheckBoxes列表时钟应用
我如何制作这样的复选框，使它们与按钮保持对齐，从打开的位置开始，并提供一个开始和结束的动画，就像在报警和放大器中一样。 Windows 10中的时钟应用程序？我试过Popups和Flyouts，但效果不一样。

看起来这个警报中的控制＆amp; Clock App实际上是从ComboBox控件扩展而来的。
因此我们可以使用ComboBox来执行此操作，例如：
<ComboBox x:Name="comboBox" VerticalAlignment="Center" HorizontalAlignment="Stretch" ItemsSource="{x:Bind comboitems}"
PlaceholderText="{x:Bind contenttext, Mode=OneWay}" DropDownClosed="comboBox_DropDownClosed" SelectionChanged="comboBox_SelectionChanged">
<ComboBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding dayofweek}" IsChecked="{Binding ischecked, Mode=TwoWay}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
要显示ComboBox上的选定日期有点复杂，我们可以在后面的代码中执行此操作：
public sealed partial class MainPage : Page, INotifyPropertyChanged
{
private ObservableCollection<comboItem> comboitems = new ObservableCollection<comboItem>();
private string _contenttext;
public string contenttext
{
get
{
return _contenttext;
}
set
{
if (value != _contenttext)
{
_contenttext = value;
OnPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged([CallerMemberName] string propertyName = "")
{
if (this.PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public MainPage()
{
this.InitializeComponent();
this.Loaded += MainPage_Loaded;
}
private int daycount;
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
showdays();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
comboitems.Clear();
comboitems.Add(new comboItem { dayofweek = "Sunday", ischecked = false });
comboitems.Add(new comboItem { dayofweek = "Monday", ischecked = true });
comboitems.Add(new comboItem { dayofweek = "Tuesday", ischecked = true });
comboitems.Add(new comboItem { dayofweek = "Wednesday", ischecked = true });
comboitems.Add(new comboItem { dayofweek = "Thursday", ischecked = true });
comboitems.Add(new comboItem { dayofweek = "Friday", ischecked = true });
comboitems.Add(new comboItem { dayofweek = "Saturday", ischecked = false });
}
private void comboBox_DropDownClosed(object sender, object e)
{
showdays();
}
private void comboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
comboBox.SelectedIndex = -1;
}
private void showdays()
{
contenttext = null;
daycount = 0;
for (int i = 0; i < comboBox.Items.Count(); i++)
{
comboItem item = comboBox.Items.ElementAt(i) as comboItem;
if (item.ischecked)
{
contenttext = contenttext + item.dayofweek.Substring(0, 3) + ", ";
daycount++;
}
}
if (daycount != 0)
{
if (daycount == 2 && contenttext == "Sun, Sat, ")
{
contenttext = "Weekends";
}
else if (daycount == 5 && contenttext == "Mon, Tue, Wed, Thu, Fri, ")
{
contenttext = "Weekdays";
}
else if (daycount == 7)
{
contenttext = "Every day";
}
else
{
contenttext = contenttext.TrimEnd(' ', ',');
}
}
else
{
contenttext = "Only once";
}
}
}
我身边的comboItem课程是这样的：
public class comboItem : INotifyPropertyChanged
{
public string dayofweek { get; set; }
private bool _ischecked;
public bool ischecked
{
get
{
return _ischecked;
}
set
{
if (value != _ischecked)
{
_ischecked = value;
OnPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged([CallerMemberName] string propertyName = "")
{
if (this.PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
也许你可以找到另一种更简单的方法来将天数转换为特定的字符串，最终我的方法可以在这里工作。

它只是移除此控件中的FontIcon并使TextBlock的ColumnSpan = 2，并将其前景更改为SystemControlForegroundAccentBrush 。如果你想自己修改它，你可以打开文档OutLine，找到这个ComboBox，右键单击它，然后选择Edit Template然后选择Edit a Copy，这样你就会得到ComboBox的默认模板：< / p>
