在後臺代碼中綁定動態創建的控件

Question

我已經動態創建了彈出窗口，該窗口在C＃代碼的運行時創建，後面充滿了xaml的內容，並且難以在後面的代碼中綁定它們。當創建它，現在，它遍歷在XAML的項目，併爲每一個相關的複選框：

ListView listView = new ListView(); 

     //Create ListViewItem for each answer 
     foreach (Answer ans in Questions.DataUsedQuestion.AnswerOptions) 
     { 
      ListViewItem item = new ListViewItem(); 
      StackPanel panel = new StackPanel(); 
      CheckBox checkBox = new CheckBox(); 
      TextBlock text = new TextBlock(); 

      panel.Orientation = Orientation.Horizontal; 
      checkBox.Margin = new Thickness(5, 0, 10, 2); 
      text.Text = ans.DisplayValue; 

      panel.Children.Add(checkBox); 
      panel.Children.Add(text); 

      item.Content = panel; 

      listView.Items.Add(item); 
     } 

我也有類似的控制其他地方在在這樣的XAML綁定的應用程序：

<TreeView ItemsSource="{Binding Path=AnswerOptions}" Height="320" Padding="5,5,5,5" Background="Transparent"> 
<TreeView.ItemTemplate > 
    <HierarchicalDataTemplate ItemsSource="{Binding Path=AnswerOptions}" 
           DataType="{x:Type QSB:Answer}" > 
     <StackPanel Orientation="Horizontal" Margin="0,2,0,2"> 

      <CheckBox IsChecked="{Binding Path=IsSelected}" > 
      </CheckBox> 
      <TextBlock Text="{Binding DisplayValue}" Margin="5,0,0,0" /> 
     </StackPanel> 
    </HierarchicalDataTemplate> 
</TreeView.ItemTemplate> 

我怎樣才能做到在後面的代碼類似於上面的東西嗎？

查看MSDN文章How to: Create a Binding in Code。

你可以寫類似：

Binding binding = new Binding("IsSelected"); 
binding.Source = ans; 
checkBox.SetBinding(CheckBox.IsCheckedProperty, binding); 

binding = new Binding("DisplayValue"); 
binding.Source = ans; 
text.SetBinding(TextBlock.TextProperty, binding);
