本文主要通过一个子datagrid来实现主次表。谢谢Kevin的博文。
代码部分与http://www.cnblogs.com/darrenji/p/3576258.html相似，这里只列出不一样的地方。
最终效果：
ProductController 让子表Product返回json字符串
public ActionResult GetJsonByCategory(int? categoryId = null)
{if (!categoryId.HasValue)
{return new EmptyResult();
}
var service = new Service();
var products = service.LoadProductsByCategory((int)categoryId);
//把Products集合对象实例序列化成json字符串
string str = JsonSerializeHelper.SerializeToJson(products);
return Content(str);
}
/Category/Index视图
展开@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<link href="~/Content/themes/default/easyui.css" rel="stylesheet" />
