我正在使用自定義對象TreeView。 目標:在TreeViewItem.Expanded事件我想打電話給A.或B.LoadChilds()取決於嵌套式的實現延遲加載。 型號: public class A
{
public A()
{
Childs = new ObservableCollection<B>();
}
public strin
我想實現延遲加載,但得到的錯誤如下 ** ERROR Error: Uncaught (in promise): Error: BrowserModule has already been loaded. If you need access to common directives such as NgIf and NgFor from a lazy loaded module, import
,所以我有一個實體和複雜類型之間的簡單關係PropertyChanged事件,我想通知實體時,複雜類型的變化,在此代碼 [Table("Bills")]
public class Bill : NotifyBase
{
//how to call SetWithNotif when this changes ?
public virtual Discount Discoun
