问题描述
是否有数据绑定的参考?我看到一些不同的数据绑定方式,但我从未找到参考。有没有?
Is there a reference for data binding? I've seen a bunch of different ways to data bind things, but I've never found a reference. Is there one?
我知道有Bind和Eval,但是Container.DataItem什么时候发挥作用?是否有其他隐藏的对象和方法可用?或者是Container.DataItem这里使用的对象?
I know there are Bind and Eval, but when does Container.DataItem come into play? Are there other "hidden" objects and methods available? Or is Container.DataItem the object that is being used here?
推荐答案
从下面的第一个链接(稍作改写):Container.DataItem是一个运行时别名绑定列表中该特定项目的DataItem。
From the first link below (paraphrasing slightly): "Container.DataItem is a runtime alias for the DataItem for this specific item in a bound list."
绝对其他类成员,再加上,其中包含 Eval
并提供方法查询绑定的Xml数据。
Definitely the other DataBinder
class members, plus TemplateControl
, which houses Eval
and provides methods to query bound Xml data.
