此绑定已被弃用,您不应再使用泛型。我该怎么办?
BindableProperty.Create<ImageGallery, IList>(
view => view.ItemsSource,
default(IList),
BindingMode.TwoWay,
propertyChanging: (bindableObject, oldValue, newValue) => {
((ImageGallery)bindableObject).ItemsSourceChanging();
},
propertyChanged: (bindableObject, oldValue, newValue) => {
((ImageGallery)bindableObject).ItemsSourceChanged(bindableObject, oldValue, newValue);
}
);
最佳答案
您可以将类型定义为Create()
方法的参数,如下所示:
public ImageGallery MyImageGallery
{
get { return (ImageGallery)GetValue(MyImageGalleryProperty); }
set { SetValue(MyImageGalleryProperty, value); }
}
public static BindableProperty MyImageGalleryProperty = BindableProperty.Create(nameof(MyImageGallery), typeof(ImageGallery), typeof(IList), default(IList), BindingMode.TwoWay,
propertyChanging: (bindableObject, oldValue, newValue) =>
{
((ImageGallery) bindableObject).ItemsSourceChanging();
},
propertyChanged: (bindableObject, oldValue, newValue) =>
{
((ImageGallery) bindableObject).ItemsSourceChanged(bindableObject, oldValue, newValue);
});
