上面是我的Xaml，我的ObsCollection的名字是

public ObservableCollection<NotesDisplay> NotesObs { get; set; }

我已在NotesDisplay模型中正确声明了ContractText列。由于某种原因，我无法将其绑定，但这在数据网格中有效。有人可以解释我在XAML中做错了吗？

由于

编辑：我查看了链接的解决方案，但是当我运行程序时，标签没有显示出来。它们在xaml

中显示

现在它还可以，但你必须在另一个TextBlock内删除你的TextBlock。

您可以更改

<TextBlock>                            
  <TextBlock Text="{Binding ContractText}"/> 
</TextBlock>

到

<TextBlock Text="{Binding ContractText}"/>

并且

<TextBlock>                            
  This is <TextBlock Text="{Binding EMSText}"/>
</TextBlock>

类似于

<StackPanel Orientation="Horizontal">
  <TextBlock>This is</TextBlock>
  <TextBlock Text="{Binding EMSText}"/>
</StackPanel>
