在我们这个小例子中,表单窗体(Form2)的数据变化后(新增、修改),可以立即反应到主窗体(Form1)上,而不用主窗体去重新加载数据,这里就必须用到数据绑定集合: private BindingList <User> UserBindingList = new BindingList<User>(); //填充集合的代码,就是将数据从数据库查询出来,然后放到该集合中,代码略 this.dataGridView1 .DataSource = UserBindingList; 光有BindingList<T> 集合还不够,它的成员对象还必须实现“属性更改通知”接口INotifyPropertyChanged
原来list<T>没有数据更新的功能,这里面需要用 ObservableCollection<T> 类 或 BindingList<T> 类 代替 List 类,看ObservableCollection
2.8、WinForm实战技能之玩转DataGridView列表控件 1)、如何优雅的绑定 DataGridView数据源(BindingList)。
在实现自己的集合之前,请考虑使用 ObservableCollection<T> 或某个现有的集合类,如 List<T>、Collection<T>和 BindingList<T>,等等。
Colletion<T>,位于System.Colletion.ObjectModel命名空间,为BindingList<T>和ObservableCollection<T>等扩展类型提供基类。
,我们发现在Collection Type一项我们有若干选项,我们可以选择我们希望生成的数据类型:Array,ArrayList,LinkedList,Generic List,Collection和BindingList
ObservableCollection 和 BindingList 有什么区别? 接口,而BindingList实现了IBindingList接口和INotifyPropertyChanged接口。 BindingList除了提供集合变化的通知外,还提供了排序、搜索和过滤等功能。 线程安全:ObservableCollection不是线程安全的,如果在多个线程上同时修改集合,可能会导致异常。 而BindingList是线程安全的,可以在多个线程上同时修改集合。 BindingList在排序和搜索操作上性能较好,但在添加、删除和移动元素时的性能较差。
class SubmitedUsersViewModel { private UserModel model = new UserModel(); public BindingList SubmitedUsersViewModel() { var data = model.GetAllUsers(); Users = new BindingList
35.ObservableCollection 和 BindingList 有什么区别? 实际的区别在于BindingList 用于WinForms,而ObservableCollection 用于WPF。 从 WPF 的角度来看,BindingList 没有得到正确支持,除非真的必须,否则您永远不会在 WPF 项目中真正使用它。36.冒泡事件和隧道事件之间的确切区别是什么?
3、任何实现IBindingList接口的类,例如BindingList(Of T)类。 4、任何实现IBindingListView接口的类,例如BindingSource类。
