等效WPF绑定语法
我需要一些关于WPF绑定语法的帮助：等效WPF绑定语法,wpf,data-binding,Wpf,Data Binding,我需要一些关于WPF绑定语法的帮助： public class ApplicationPresenter { public ObservableCollection<Quotes> PriceList {get;} } public class WebSitePricesView { private IApplicationPresenter presenter { get { return (ApplicationPresenter)Da
public class ApplicationPresenter
{
public ObservableCollection<Quotes> PriceList {get;}
}
public class WebSitePricesView
{
private IApplicationPresenter presenter
{
get { return (ApplicationPresenter)DataContext; }
}
// public ObservableCollection<Quotes> PriceList
// {
// get {return presenter.PriceList; }
}
}
公共类应用程序演示器
{
公共ObservableCollection价格表{get；}
}
公共类网站价格视图
{
专用IApplicationPresenter演示者演示者
{
获取{return（ApplicationPresenter）DataContext；}
}
//公共可观测收集价格表
// {
//获取{return presenter.PriceList；}
}
}
