问题描述
我将如何绑定到MVVMCross中的祖父母?
How would I bind to a grandparent in MVVMCross?
我有一个List<string>，我将其绑定到具有自己的项目模板"A"的MvxLinearLayout.当用户单击"A"中的按钮时，我想在其父级(即List<string>的所有者)中触发ICommand.
I have a List<string> which I'm binding to a MvxLinearLayout with its own item template "A". When the user clicks on the button in "A" I would like to fire an ICommand in its parent (i.e. the owner of the List<string>).
我也有类似的祖父母关系.
I also have a similar situation with a grandparent relation.
我该怎么做?
推荐答案
列表或任何其他mvx数据绑定上下文中目前没有父绑定访问.
There is no parent binding access in lists or any other mvx data binding context currently.

我已经多次回答类似的问题.每次我邀请人们提出功能请求，想法或问题时，例如 https://github .com/slodge/MvvmCross/issues/35 .尽管可能有3或4个问题，但似乎没有人愿意去跟进，所以我认为这不是一个重要功能.
I've answered questions similar to this several times. Each time i invite people to raise feature requests, ideas or pulls to issues such as https://github.com/slodge/MvvmCross/issues/35 . While there have been perhaps 3 or 4 of these questions, no-one ever seems bothered enough to follow up, so i guess it's not an important feature.
