How to display items horizontally in a listbox control?

I am developing window phone 7 application. I am new to the window phone 7 application. I have the following listbox control in my application

<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>

In the above listbox control items are displayed vertically. I want to display the items in a listbox control horizonatlly. So I am using the following code.

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

but when I put the two textblock inside stackpanel it gives error. For this I am using the following code

<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>

I am trying for the following code. In the following code I am getting error

<ListBox Margin="0,355,70,205" 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>

I am getting the error "Cannot explicitly modify children collection of Panel used as ItemsPanel for ItemsControl.ItemsControl geneartes child elements for Panel"

I am using the following function to display the data in the ListBox:

public void WeekSumValue(int TransactionType_ID)
{
    UserInterfaceManager UserInterfaceManagerObj = new UserInterfaceManager();
    List<UserInterfaceManager.TotalSummary> WeekSummary = new List<UserInterfaceManager.TotalSummary>();           
    ObservableCollection<AmountCurrency> WeekIncomeSumCollection = new ObservableCollection<AmountCurrency>();

    WeekSummary = UserInterfaceManagerObj.LoadWeekSum(SelectedButtonName, TransactionType_ID, selectedDate);

    foreach (UserInterfaceManager.TotalSummary 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开发者_StackOverflow社区 = "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;
    }
}

In the above function data is coming dynamically. There can be two, three or more records also there can be no record. I am binding this dynamic data to the textblocks which are inside the listbox

I am using the following class used in the above code

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;
    }
}

How should I put the above two textbock inside the listbox which will display the items horizonatlly ? Can you please provide me any code or link through which I can resolve the above issue ? If I am doing anything wrong then please guide me.

It looks to me like you've got the two text blocks inside the wrong part of the template.

These two text blocks should be in the ListBox.ItemTemplate, not in the ListBox.ItemsPanelTemplate:

<ListBox ItemsSource="{Binding Items}">
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"></StackPanel>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Margin="0,0,0,17" Width="300" 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>

If you want to understand how this control works, then start from a working "basic" control which shows items and then look at adding the ItemsPanelTemplate to that working sample.

Replace DataContext="{Binding}" with ItemsSource="{Binding}" that works for me.
