复杂的WebGrid在MVC 3绑定 [英] Complex WebGrid Binding in MVC 3

问题描述

让我们说我有这样的父对象（伪code）

Let's say I have a Parent object like this (in pseudo code)

public Parent()
  string FirstName
  string LastName
  IEnumarable<Child> Children
  Child GetOldestChild()  <- A function that returns the oldest child in Children

public Child()
  string ChildFirstName
  string ChildLastName
  int ChildAge

好了，我想绑定的WebGrid的IEnumarable＆LT;家长>，每一行我想要显示的父姓和名，最大的孩子的名字/姓氏/年龄

Ok, so I want to bind a WebGrid an IEnumarable< Parent >, and in each row I want to display the first and last name of the parent, and the firstname/lastname/age of the oldest child.

获取父列很容易，我可以绑定是这样的：

Getting the parent columns is easy, I can just bind like this:

grid.Column("FirstName")

但是，让老大的数据是什么，我不知道该怎么办。这并不工作，但它是我想要完成的任务：

But getting the oldest child data is what I don't know how to do. This doesn't work, but it's what I want to accomplish:

grid.Column("GetOldestChild().ChildFirstName")

希望我失去了一些东西简单...

Hopefully I'm missing something simple...

推荐答案

试试这个方法：

public Parent()
  string FirstName
  string LastName
  IEnumarable<Child> Children
  private Child GetOldestChild()
  public Child OldestChild { get { return GetOldestChild() } };

public Child()
  string ChildFirstName
  string ChildLastName
  int ChildAge

grid.Column("OldestChild.ChildFirstName")
