在绑定源当前项更改事件上重新分配 textbox.text
我正在学习绑定源等。我已经添加了我的文本框数据绑定，如下所示：
txtTitle.DataBindings.Add("Text", bindingNavigator1.BindingSource.Current, "Title");
当用户单击导航器上的下一个按钮时，我是否必须处理绑定源当前项目更改事件来表示
txtTitle.Text = ((MyObject)bindingsource.CurrentItem).Title??
我认为这将是自动的，因为我有一个很多控件看起来很乏味
I am just learning bindingsources etc. I have added my textbox databindings like so:
txtTitle.DataBindings.Add("Text", bindingNavigator1.BindingSource.Current, "Title");
When the user clicks the next button on the navigator do I have to handle the bindingsource currentitem changed event to say
txtTitle.Text = ((MyObject)bindingsource.CurrentItem).Title??
I would have thought this would be automatic as I have a lot of controls so seems tedious

您应该绑定到绑定源本身，如下所示：
然后您不需要处理任何进一步的事件。正如你所说，那会很乏味。
You should bind to the bindingsource itself as in:
Then you don't need to handle any further events. As you say, that would be tedious.
