C#WPF使用ItemsControl管理嵌套结构

因此，我已经发布了一个关于WPF中嵌套控件结构的问题，如下所示： 我收到的解决方案如下：

<ItemsControl ItemsSource="{Binding SomeCollectionOfViewModel}">
   <ItemsControl.ItemsPanel>
      <ItemsPanelTemplate>
         <UniformGrid/>
      </ItemsPanelTemplate>
   </ItemsControl.ItemsPanel>
   <ItemsControl.ItemTemplate>
       <DataTemplate>
          <ItemsControl ItemsSource="{Binding SomeCollection}">   <!-- Nested Content -->
              ...
       </DataTemplate>
   <ItemsControl.ItemTemplate>
</ItemsControl>

...

我已经使用了该解决方案，并提出了以下建议：

<!-- The UniformGrids - boxes -->
<ItemsControl ItemsSource="{Binding UniformGridCollection}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>

        <ItemsControl.ItemTemplate>
            <DataTemplate>

                <!-- The TextBoxes - Cells -->
                <ItemsControl ItemsSource="{Binding TextBoxCollection}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <UniformGrid />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                </ItemsControl>

            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

public partial class MainWindow : Window
    {
        private readonly ObservableCollection<UniformGrid> uniformGridCollection = new ObservableCollection<UniformGrid>();
        public ObservableCollection<UniformGrid> UniformGridCollection { get { return uniformGridCollection; } }
        private readonly ObservableCollection<UniformGrid> textBoxCollection = new ObservableCollection<UniformGrid>();
        public ObservableCollection<UniformGrid> TextBoxCollection { get { return textBoxCollection; } }
        public MainWindow()
        {
            InitializeComponent();
            for (int i = 1; i <= 9; i++)
            {
                UniformGrid box = new UniformGrid();
                UniformGridCollection.Add(box);
                UniformGrid cell = new UniformGrid();
                TextBoxCollection.Add(cell);
            }
            DataContext = this;
        }
    }

这是C侧：

<!-- The UniformGrids - boxes -->
<ItemsControl ItemsSource="{Binding UniformGridCollection}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>

        <ItemsControl.ItemTemplate>
            <DataTemplate>

                <!-- The TextBoxes - Cells -->
                <ItemsControl ItemsSource="{Binding TextBoxCollection}">
                    <ItemsControl.ItemsPanel>
                        <ItemsPanelTemplate>
                            <UniformGrid />
                        </ItemsPanelTemplate>
                    </ItemsControl.ItemsPanel>
                </ItemsControl>

            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

public partial class MainWindow : Window
    {
        private readonly ObservableCollection<UniformGrid> uniformGridCollection = new ObservableCollection<UniformGrid>();
        public ObservableCollection<UniformGrid> UniformGridCollection { get { return uniformGridCollection; } }
        private readonly ObservableCollection<UniformGrid> textBoxCollection = new ObservableCollection<UniformGrid>();
        public ObservableCollection<UniformGrid> TextBoxCollection { get { return textBoxCollection; } }
        public MainWindow()
        {
            InitializeComponent();
            for (int i = 1; i <= 9; i++)
            {
                UniformGrid box = new UniformGrid();
                UniformGridCollection.Add(box);
                UniformGrid cell = new UniformGrid();
                TextBoxCollection.Add(cell);
            }
            DataContext = this;
        }
    }

对于（int i=1；i您没有在任何地方定义任何
TextBox
es，这就是为什么您没有在可视化树中获得任何
TextBox
es的原因：

<Window x:Class="MiscSamples.NestedItemsControls"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="NestedItemsControls" Height="300" Width="300">
    <ItemsControl ItemsSource="{Binding Level1}">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <UniformGrid/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <ItemsControl ItemsSource="{Binding Level2}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding Value}"/> <!-- You Are missing this! -->
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Window>

请注意，如果希望这些集合在运行时动态更改，则必须将
列表
s更改为
可观察集合
s

另外请注意，您必须正确实现
INotifyPropertyChanged
。
您的集合不应该是UI元素类型，而应该是ViewModel类型。您可以在上面指定吗？非常感谢，非常感谢您的帮助！
