如何将数据网格与数据绑定?

这个想法是:您不应该将控件中的任何数据立即保存到文件中.这种设计很难维护.您需要拥有一个单独的数据层，无论它是什么，并将其绑定到UI控件，并从数据层而不是控件中保存数据.即使您没有使用数据绑定，这也意味着您通过手动"代码绑定了此控件，其设计应相同:您将数据层中的数据填充到视图中，视图的编辑应使数据无效并与之同步数据层，数据层中的更改应更新视图.这种方法最接近的建筑模式是MVC.

我建议您学习并分析以下建筑模式的适用性( http://en.wikipedia .org/wiki/Architectural_pattern_(computer_science) [^ ]):

MVVM —模型视图视图模型，
http://en.wikipedia.org/wiki/Model_View_ViewModel [> http://en.wikipedia.org/wiki/Model-view-controller [ ^ ]))，

MVA —模型视图适配器，
http://en.wikipedia.org/wiki/Model–view–adapter [ ^ ]，

MVP —模型视图呈现器，
> http://en.wikipedia.org/wiki/Model-view-presenter [ ^ ].

请注意这些架构的动机.如果您了解它，就可以提出更好的设计思路.

How you bind data grid with data?

The idea is: you should not save any data from controls immediately to file. This design is hard to maintain. You need to have a separate data layer, whatever it is and bind it to you UI controls and save your data from you data layer, not from control. Even of you don''t use data binding, it means you bind this control through "manual" code, the design should be the same: you populate data from data layer to view, editing of the view should invalidate data and synchronize it with data layer, changes in data layer should update the view. The closest architectural pattern for this approach is MVC.

I suggest you learn and analyze applicability of the following architectural patterns (http://en.wikipedia.org/wiki/Architectural_pattern_(computer_science)[^]):

MVVM — Model View View Model,
http://en.wikipedia.org/wiki/Model_View_ViewModel[^],

MVC — Model-View-Controller,
http://en.wikipedia.org/wiki/Model-view-controller[^]),

MVA — Model-View-Adapter,
http://en.wikipedia.org/wiki/Model–view–adapter[^],

MVP — Model-View-Presenter,
http://en.wikipedia.org/wiki/Model-view-presenter[^].

Pay attention for the motivation of those architectures. If you understand it, you would be able to create better design ideas.
