推荐答案

1.  什么不起作用或起作用了.  您确实没有提出问题.

1.  what is not working or is it working.  You really did not ask a question.

2.可以在ItemsSource中找到ID(如果这就是行ID的含义).   XAML不会显示ItemsSource的绑定，但是由于列具有绑定，所以我只能假定您在代码中提供了ItemsSource.

2.  the ID (if that is what you meant by Row ID) can be found in the ItemsSource.  The XAML does not show a binding for the ItemsSource but since the columns have bindings I can only assume you are providing the ItemsSource in code.

3.  更新数据库(您不说哪个数据库)是API的功能(您再也没有告诉我们)，并且通常使用DataGrid而不是ListView进行简单的编辑.  实体框架会非常简单.

3.  Updating a DB (you don't say which DB) is a function of the API (which again you haven't told us) and a DataGrid rather than a ListView is generally used for simple editing.  Entity Framework would be very simple.
