我正在尝试使用longlistselector控件来显示People和他们可能拥有的孩子的列表。有些可能有1个孩子,有些可能有更多。

我正在尝试使用ItemTemplate

<phone:PhoneApplicationPage.Resources>
    <DataTemplate x:Key="KidsTemplate">
        <StackPanel Grid.Column="1" VerticalAlignment="Top">
            <TextBlock Text="{Binding KidsName}"/>
        </StackPanel>
    </DataTemplate>
    <DataTemplate x:Key="ListTemplate">
        <StackPanel Grid.Column="1" VerticalAlignment="Top">
            <TextBlock Text="{Binding Name}"/>
            <TextBlock Text="{Binding Address}"/>
            <ListBox x:Name="PersonKids"
                     ItemTemplate="{StaticResource KidsTemplate}">
            </ListBox>
        </StackPanel>
    </DataTemplate>
</phone:PhoneApplicationPage.Resources>
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <!--TitlePanel contains the name of the application and page title-->
    <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
        <TextBlock Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}" Margin="12,0"/>
        <TextBlock Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
    </StackPanel>

    <!--ContentPanel - place additional content here-->
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <phone:LongListSelector x:Name="MultiList"
                            ItemsSource="{Binding Person}"
                            ItemTemplate="{StaticResource ListTemplate}">
        </phone:LongListSelector>
    </Grid>
</Grid>

尝试使用以下课程

public class PersonDetail
{
    public string Name { get; set; }
    public string Address { get; set; }
    public Kids PersonKids { get; set; }
}
public class Kids
{
    public string KidsName { get; set; }
}

enter image description here

任何帮助都会很棒。

答案 0 :(得分:4)

首先,你把你的课写错了:

public class PersonDetail
{
    public string Name { get; set; }
    public string Address { get; set; }
    public List<Kid> PersonKids { get; set; }
}
public class Kid
{
    public string KidsName { get; set; }
}

一个人有一个孩子的名单,而不是一个孩子。然后为个人修复模板:

<ListBox x:Name="PersonKids"
         ItemsSource="{Binding PersonKids}"
         ItemTemplate="{StaticResource KidsTemplate}">
</ListBox>

现在您需要为您的网页设置相应的DataContext。首先,将以下属性添加到页面的类中:

public ObservableCollection<PersonDetail> Persons { get; set; }

并将以下代码添加到构造函数中:

Persons = new ObservableCollection();    DataContext = this;

如果您将人员添加到Persons集合中,则应该正确显示。
