WPF ContentPresenter仅显示列表中的第一项

我正在尝试创建一个WPF应用程序,其中有一个显示帐户列表的StackPanel。每个帐户的代码后面都有一个Account对象,存储在List结构中。我想将此数据绑定到我的WPF,但我不想要列表框。

相反,我定义了每个帐户摘要应如何显示的模板。然后我想将它们堆叠在StackPanel中并将其称为一天。

问题是数据绑定只接受列表中的第一项,就是这样。如何绑定它以便有效地创建一个包含格式良好的数据块的小堆栈列表?

以下是相关的WPF代码:

<StackPanel Name="sp_AccountList" Margin="0,0,0,0" VerticalAlignment="Top">
    <StackPanel.Resources>
    <svc:AccountBalanceColorConverter x:Key="accountColorConverter" />
    <Style x:Key="AccountSummaryBackgroundGradient" TargetType="{x:Type StackPanel}">
    <!-- nice formatting code here -->
    </Style>
    <Style x:Key="AccountSummaryNameStyle" TargetType="{x:Type TextBlock}">
        <Setter Property="Padding" Value="10,0,0,0" />
        <Setter Property="FontSize" Value="18" />
        <Setter Property="Height" Value="20" />
        <Setter Property="FontFamily" Value="Cambria" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="Background" Value="Transparent" />
    </Style>
    <Style x:Key="AccountSummaryBalanceStyle" TargetType="{x:Type TextBlock}">
        <Setter Property="Padding" Value="10,0,0,0" />
        <Setter Property="FontSize" Value="14" />
        <Setter Property="Height" Value="20" />
        <Setter Property="FontFamily" Value="Cambria" />
        <Setter Property="Background" Value="Transparent" />
    </Style>                    
    <ObjectDataProvider x:Key="accounts"
                        ObjectType="{x:Type svc:AccountService}"
                        MethodName="ListAccounts" />
    <DataTemplate x:Key="AccountSummaryLayout">
    <StackPanel Orientation="Vertical" Style="{StaticResource AccountSummaryBackgroundGradient}">
        <TextBlock Text="{Binding Path=Name}" Style="{StaticResource AccountSummaryNameStyle}" />
        <StackPanel Orientation="Horizontal">
            <TextBlock Foreground="{Binding Path=TotalAccountBalance, Converter={StaticResource accountColorConverter} }" Text="{Binding Path=TotalAccountBalance, Mode=OneWay}" Style="{StaticResource AccountSummaryBalanceStyle}" />
            <TextBlock Foreground="{Binding Path=AvailableAccountBalance, Converter={StaticResource accountColorConverter} }" Text="{Binding Path=AvailableAccountBalance, Mode=OneWay}" Style="{StaticResource AccountSummaryBalanceStyle}" />
        </StackPanel>
    </StackPanel>
    </DataTemplate>
    </StackPanel.Resources>
    <StackPanel Orientation="Vertical">
        <ContentPresenter x:Name="AccountSummaryPresenter" ContentTemplate="{StaticResource AccountSummaryLayout}" Content="{DynamicResource accounts}" />
    </StackPanel>
</StackPanel>

StackPanel没有ItemsSource属性,其子控件不是databindable。

你可以做的是创建一个ItemsPatrol,它使用StackPanel作为其Itemshost。

     <ScrollViewer>
            <ItemsControl ItemsSource="{Binding Source={StaticResource accounts}}">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <StackPanel IsItemsHost="True" Orientation="Vertical" />
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
                <ItemsControl.ItemTemplate>
                ...
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        <ScrollViewer>
