我正在开发 Windows Phone 7 应用程序。我是 Windows Phone 7 应用程序的新手。我的应用程序中有以下列表框控件
<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,控制项是垂直显示的。我想水平显示列表框控件中的项目。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入堆栈面板时,它会出现错误。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="0,355,70,205" 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>
我收到错误“无法显式修改用作 ItemsControl.ItemsControl 的 ItemsPanel 的 Panel 的子集合。ItemsControl 生成 Panel 的子元素”
我正在使用以下函数来显示列表框中的数据:
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 = "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,数据是动态传入的。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
我正在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;
}
}
我应该如何将上述两个文本块放入列表框中以水平显示项目?您能给我提供任何可以解决上述问题的代码或链接吗?如果我做错了什么,请指导我。
