我的 WPF 应用程序代码在 .cs 文件中定义的函数调用上生成面板。代码中使用了 ItemControl 来生成这些 Panels 。我想通过它的按钮更改选定面板中定义的文本框文本的文本对齐方式。查询：我单击按钮，选择面板 TextBox 的对齐方式从左到右和从右到左更改，如果选择滑块移动，现在执行对齐设置。这里的代码是：

XAML 文件

<ItemsControl x:Name="lstItemsClassM">
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <StackPanel Orientation="Vertical">
        <Button Content="{Binding Alignment, Mode=TwoWay}"
                Click="Button_Click"
                Tag="{Binding PKId}" />
        <TextBox x:Name="txtText"
                 Width="300"
                 Height="100"
                 Text="{Binding Text, Mode=TwoWay}"
                 FontSize="{Binding FontSize, Mode=OneWay}"
                 TextAlignment="{Binding Alignment, Mode=OneWay}" />
        <Slider Minimum="10"
                Maximum="30"
                Value="{Binding FontSize, Mode=TwoWay}" />
      </StackPanel>
    </DataTemplate>
  </ItemsControl.ItemTemplate>

.CS 文件

 protected ObservableCollection<ClassM> texts = new ObservableCollection<ClassM>();
    int dv;
    public Window2()
    {
        InitializeComponent();
        dv=1;
        texts.Add(new ClassM() { PKId=dv, Text = "Test 1" });
        dv=2;
        texts.Add(new ClassM() { PKId=dv, Text = "Test 2" });

        lstItemsClassM.ItemsSource = texts;
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        var myValue = ((Button)sender).Tag;
           foreach (var f in texts.ToList())
            {
                if (f.PKId.ToString() == myValue.ToString())
                {
                    f._alignment = "Right";
                    MessageBox.Show(f._alignment);
                }
            }
    }    
}


public class ClassM : INotifyPropertyChanged
{
    private string _id;
    private int _pkid;
    private string _text;
    private double _fontSize = 10;
    public string _alignment="Left";

    public int PKId
    {
        get { return _pkid; }
        set
        {
            if (value != _pkid)
            {
                _pkid = value;
                NotifyPropertyChanged();
            }
        }
    }
    public string Id
    {
        get { return _id; }
        set
        {
            if (value != _id)
            {
                _id = value;
                NotifyPropertyChanged();
            }
        }
    }
    public string Text
    {
        get { return _text; }
        set
        {
            if (value != _text)
            {
                _text = value;
                NotifyPropertyChanged();
            }
        }
    }
    public double FontSize
    {
        get { return _fontSize; }
        set
        {
            if (value != _fontSize)
            {
                _fontSize = value;
                NotifyPropertyChanged();
            }
        }
    }
    public string Alignment
    {
        get { return _alignment; }
        set
        {
            if (value != _alignment)
            {
                _alignment = value;
                NotifyPropertyChanged();
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void NotifyPropertyChanged(String propertyName = "")
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

}

对齐意味着 Textbox.Text 对齐left to right或right to left

最好的解决方案是使用 RichTextBox 来对齐您的文本。如果您想我可以建议一种实现来读取文字字符串和格式。
