WPF数据网格中的数据绑定(C#4.0)

基本上。它设置RegistryAction对象的列表,并将其与DataGrid绑定。然而,我发现每当我在butDelete_中运行代码时,尽管列表已更新,但网格上的内容并未得到更新
简言之,有人能认出我错过了什么吗
Martin。您需要执行
注册表操作。MSDN还有一个。mRegistryActions
应该是observedcollection
:
protected ObservableCollection<RegistryAction> mRegistryActions = new ObservableCollection<RegistryAction>();
protectedobservedcollection mRegistryActions=newobservedcollection();
一次犯规就彻底解决了问题-干杯。应该想到的是,如果网格没有听到集合中的更改,那么可能集合没有大声谈论这些更改+1并接受。+1-干杯。。。INotifyCollectionCHange也需要在列表中进行更改-当然,我总是可以在子类中进行更改。。。
namespace FRC
{
public class RegistryAction
{
public string RegKeyPath { get; set; }
public bool DeletePath { get; set; }
public RegistryAction()
{
this.DeletePath = false;
this.RegKeyPath = "";
}
}
}
protected ObservableCollection<RegistryAction> mRegistryActions = new ObservableCollection<RegistryAction>();
