Question

我想在点击一个按钮的同时逐一添加Listpickers，同时对Listpickers的控件应该在listpicker的每个添加中向下移动。请给我一个想法。

用于创建listpicker的XAML代码。

   <toolkit:ListPicker Grid.Row="0"  Margin="5,76,226,-52" x:Name="list" ItemTemplate="{StaticResource PickerItemTemplate}" ItemCountThreshold="3"
                            FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}"   FullModeHeader="Select your Monthly Debts:" SelectedIndex="2"  CacheMode="BitmapCache"
                            FontFamily="Arial Black" FontSize="32" FontWeight="ExtraBlack"/>

C＃代码：

   List<payment> source = new List<payment>();
        source.Add(new payment() { Name = "Car Payment" });
        source.Add(new payment() { Name = "Credit UnionLoan" });
        source.Add(new payment() { Name = "Spousal Support" });
        source.Add(new payment() { Name = "Child Support" });
        source.Add(new payment() { Name = "Visa" });
        source.Add(new payment() { Name = "MasterCard" });
        this.list.ItemsSource = source;

namespace NewUIChanges
{
public class payment
{
    public string Name
    {
        get;
        set;
    }
}
}

您可以像任何其他控件一样动态地将ListPickers添加到UI。

对于您向下移动其他控件的其他要求，我建议您对上面显示的ListPicker XAML代码进行一些小改动。

<StackPanel x:Name="StackPanelListPickers" Grid.Row="0">
<toolkit:ListPicker  Margin="5,76,226,-52" x:Name="list" ItemTemplate="{StaticResource PickerItemTemplate}" ItemCountThreshold="3"
                        FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}"   FullModeHeader="Select your Monthly Debts:" SelectedIndex="2"  CacheMode="BitmapCache"
                        FontFamily="Arial Black" FontSize="32" FontWeight="ExtraBlack"/>
</StackPanel>

然后在您要添加ListPickers的代码后面执行以下操作：

//Generate a dynamic listpicker
ListPicker lp = new ListPicker() { Name = "List2" };
lp.Template = this.Resources["PickerItemTemplate"] as ControlTemplate;
lp.FullModeItemTemplate = this.Resources["FullModeItemTemplate"] as DataTemplate;
//And all other properties of "lp" as you need ..I am not writing all here

//Now add this new Listpicker to the stackpanel which is the child of the Grid
this.StackPanelListPickers.Children.Add(lp);

您可以创建ListPicker并使用绑定到ObservableCollection。

ObsarvableCollection的优点是您的更改会在视图上自动更新。有关更多信息，请参阅：MSDN。另请查看stackoverflow.com/questions/9745279
