在 Avalonia 的 ControlTemplate 中引发水平滚动更改事件时如何绑定 2 个 ScrollViewer 控件？

Question

我正在制作自定义 table 控件。它有 2 个滚动查看器，一个用于行部分，另一个隐藏在列部分中。它们都位于 DataTemplate 中。当用户水平滚动行部分时，我想水平滚动列部分。我尝试将 Offset 属性绑定到彼此，但不知道如何仅对 X 轴执行此操作。这在 xaml 端是否可能，还是必须在 C# 中发生？两种方式都可以，只是想弄清楚如何去做。

Avalonia's Github 那边有人回答了。我会在这里分享。我想多了。您可以只绑定整个 Offset 对象。

<StackPanel Spacing="5">
  <ScrollViewer x:Name="ScrollViewer1" HorizontalScrollBarVisibility="Visible" Height="50">
    <Border MinWidth = "2000" Background="{DynamicResource SystemAccentColor}">
    <TextBlock>This is a very very long Text in ScrollViewer 1. This is a very very long Text in ScrollViewer 1. This is a very very long Text in ScrollViewer 1. This is a very very long Text in ScrollViewer 1.  </TextBlock>
    </Border>
  </ScrollViewer>
  <ScrollViewer x:Name="ScrollViewer2" HorizontalScrollBarVisibility="Visible" Height="50"
                Offset="{Binding #ScrollViewer1.Offset, Mode=TwoWay}">
    <Border MinWidth = "2000" Background="{DynamicResource SystemAccentColorDark2}">
      <TextBlock>This is a very very long Text in ScrollViewer 2. This is a very very long Text in ScrollViewer 2. This is a very very long Text in ScrollViewer 2. This is a very very long Text in ScrollViewer 2.  </TextBlock>
    </Border>
  </ScrollViewer>
</StackPanel>
