一个很好的集合在C＃绑定到一个DataGridView使用时 [英] A good collection to use when binding to a DataGridView in C#

问题描述

什么是最好的集合数据绑定列表在C＃中的DataGridView时使用？我目前只使用一个泛型列表，但是当有添加或从列表中删除对象的数据网格不会更新。我看着使用的BindingList或的ObservableCollection，但不能决定这将是最好使用将更新并易于梳理/过滤器，而无需重新绑定到数据网格。我目前在windows窗体工作的.Net 3.5，计划不久将到WPF框架。

What would be the best collection to use when binding a list of data to a DataGridview in C#? I'm currently using just a Generic List but the data grid doesn't update when there is objects added or removed from the list. I've looked at using a BindingList or a ObservableCollection, but can't decide which would be best to use that would update and be easy to sort/filter without having to rebind to the data grid. I'm currently working in windows form on .Net 3.5 framework with plans to move over to WPF soon.

推荐答案

• 的ObservableCollection< T> 将不为其工作， DataGridView的：它实现 INotifyCollectionChanged ，而不是 IBindingList的和 DataGridView的不知道 INotifyCollectionChanged 。其目的是为WPF的绑定和Windows窗体


• 不使用的BindingList< T> 是一个不错的选择，但要注意它不支持排序或筛选开箱。但是，你可以找到这些功能的一些自定义实现在网络上。


• 数据表可能是你最好的选择，如果你需要整理和/或过滤能力

• ObservableCollection<T> won't work for a DataGridView : it implements INotifyCollectionChanged, not IBindingList, and the DataGridView doesn't know about INotifyCollectionChanged. It is intended for WPF bindings and is not used in Windows Forms
• BindingList<T> is a good option, but note that it doesn't support sorting or filtering out of the box. However, you can find some custom implementations of these features on the web.
• DataTable is probably your best option if you need sorting and/or filtering capability
