推荐答案

如果您要遵循MVVM，一种解决方案是将您的数据库对象（数据集/表）包装到模型中，将模型包装到视图模型并将该视图模型的可观察集合绑定到网格的ItemsSource。然后，一旦更改了该复选框的值，就可以在绑定文本框的属性的setter中捕获它，从那里可以更新模型，直到数据库。

If you''re going to follow MVVM, one solution is to wrap your DB objects(dataset/table) into a model, wrap the model to a viewmodel and bind an observable collection of that viewmodel to the ItemsSource of the grid. Then once you change the value of that check box, you can catch it in the setter of the property where you bind the text box, from there you can update the model, down to the database.
