silverlight – 如何在列表框控件中水平显示项目？

<ListBox Margin="0,355,70,205" Name="WeekSumMaryListBox" DataContext="{Binding}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock textwrapping="Wrap" Width="150" Text="{Binding amount}" Foreground="Orange"></TextBlock>
                <TextBlock textwrapping="Wrap" Width="150" Text="{Binding Currency}" Foreground="Orange"></TextBlock>                            
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>

    <ListBox.Template>
        <ControlTemplate>
            <ScrollViewer HorizontalScrollBarVisibility="Visible">
                <ItemsPresenter />
            </ScrollViewer>
        </ControlTemplate>
    </ListBox.Template>
</ListBox>

在上面的列表框中,控件项目是垂直显示的.我想在列表框控件中显示项目.所以我使用以下代码.

<ListBox.ItemsPanel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Horizontal"/>
    </ItemsPanelTemplate>
</ListBox.ItemsPanel>

但是当我将两个文本块放在stackpanel中时,它会出错.为此,我使用以下代码

<StackPanel Orientation="Horizontal">
    <TextBlock textwrapping="Wrap" Width="150" Text="{Binding amount}" Foreground="Orange"></TextBlock>
    <TextBlock textwrapping="Wrap" Width="150" Text="{Binding Currency}" Foreground="Orange"></TextBlock>                            
</StackPanel>

我正在尝试以下代码.在下面的代码中我收到错误

<ListBox Margin="0,205" Name="WeekSumMaryListBox" DataContext="{Binding}">
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock textwrapping="Wrap" Width="150" Text="{Binding amount}" Foreground="Orange"></TextBlock>
                <TextBlock textwrapping="Wrap" Width="150" Text="{Binding Currency}" Foreground="Orange"></TextBlock>
            </StackPanel>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBox.Template>
        <ControlTemplate>
            <ScrollViewer HorizontalScrollBarVisibility="Visible">
                <ItemsPresenter />
            </ScrollViewer>
        </ControlTemplate>
    </ListBox.Template>
</ListBox>

我收到错误“无法显式修改Panel的子集合,用作ItemsConnel的ItemsPanel.ItemsControl生成Panel的子元素”

我使用以下函数来显示ListBox中的数据：

public void WeekSumValue(int transactionType_ID)
{
    UserInterfaceManager UserInterfaceManagerObj = new UserInterfaceManager();
    List<UserInterfaceManager.@R_418_10586@lSumMary> WeekSumMary = new List<UserInterfaceManager.@R_418_10586@lSumMary>();           
    ObservableCollection<amountCurrency> WeekIncomeSumCollection = new ObservableCollection<amountCurrency>();

    WeekSumMary = UserInterfaceManagerObj.LoadWeekSum(SELEctedButtonName,transactionType_ID,SELEctedDatE);

    foreach (UserInterfaceManager.@R_418_10586@lSumMary vWeekSumMary in WeekSumMary)
    {
        WeekIncomeSumCollection.Add(new amountCurrency(vWeekSumMary.amount,vWeekSumMary.Currency));
    }

    if (WeekIncomeSumCollection.Count != 0 && SumMaryComboBox.SELEctedIndex == 0)
    {
        WeekSumMaryListBox.Itemssource = WeekIncomeSumCollection;
    }
    else if (WeekIncomeSumCollection.Count != 0 && SumMaryComboBox.SELEctedIndex == 2)
    {
        MonthSumMaryListBox.Itemssource = WeekIncomeSumCollection;
    }
    else
    {
        ObservableCollection<TextBlock> NoRecordsCollection = new ObservableCollection<TextBlock>();
        TextBlock NoRecordsTextBlock = new TextBlock();
        NoRecordsTextBlock.Text = "No record found";
        NoRecordsTextBlock.FontSize = 25;
        NoRecordsTextBlock.Foreground = new SolidColorBrush(Colors.Gray);
        NoRecordsCollection.Add(NoRecordsTextBlock);

        if (SumMaryComboBox.SELEctedIndex == 0)
            WeekSumMaryListBox.Itemssource = NoRecordsCollection;

        if (SumMaryComboBox.SELEctedIndex == 2)
            MonthSumMaryListBox.Itemssource = NoRecordsCollection;
    }
}

在上面的函数中,数据是动态传递的.可以有两个,三个或更多记录也可以没有记录.我将此动态数据绑定到列表框内的文本块

我使用上面代码中使用的以下类

public class amountCurrency
{
    public int amount { get; set; }
    public String Currency { get; set; }

    public amountCurrency(int amount,String Currency)
    {
        this.amount = amount;
        this.Currency = Currency;
    }
}

我应该如何将上面两个textbock放在列表框中,这将显示项目的范围？能否请您提供我可以解决上述问题的任何代码或链接？如果我做错了什么,请指导我.
