显示基于父网格的子网格

Question

我有一个要求，我需要显示父网格。 根据父项中选择的项目，获取数据并显示在子网格中。我目前正在做一个UI模型，并且还没有建立所有模型。因此，您在下面看到的模型只是样本。

我可以使用我需要的数据显示父网格。我还有代码在父网格中选择一行，并使用ajax post将行数据发送到控制器。我需要使用这些数据来填充子网格。这是我不确定我做错了什么的一步。

我的控制器和视图如下：你能帮忙吗？ --controller：

public ActionResult GetData()
{

    List<Hierarchy> lh = new List<Hierarchy>();
    Hierarchy m = new Hierarchy();
    m.Hierarchy1 = 1;
    m.Hierarchy2 = 2;
    m.Hierarchy3 = 3;
    lh.Add(m);

    Hierarchy n = new Hierarchy();
    n.Hierarchy1 = 11;
    n.Hierarchy2 = 22;
    n.Hierarchy3 = 33;
    lh.Add(n);

    Hierarchy o = new Hierarchy();
    o.Hierarchy1 = 111;
    o.Hierarchy2 = 222;
    o.Hierarchy3 = 333;
    lh.Add(o);

    return Json(new { rows = lh }, JsonRequestBehavior.AllowGet);
}


public ActionResult EditDescription(Hierarchy info)
{

    List<Product> plist = new List<Product>();

    if (info.Hierarchy1 == 1 && info.Hierarchy2 == 2 && info.Hierarchy3 == 3)
    {
        Product p = new Product();
        p.ProductId = 1;
        p.Productdesc = "ABC";
        plist.Add(p);

        Product q = new Product();
        q.ProductId = 2;
        q.Productdesc = "DEF";
        plist.Add(q);
    }

    if (info.Hierarchy1 == 11 && info.Hierarchy2 == 22 && info.Hierarchy3 == 33)
    {
        Product p = new Product();
        p.ProductId = 11;
        p.Productdesc = "ABCD";
        plist.Add(p);

        Product q = new Product();
        q.ProductId = 22;
        q.Productdesc = "DDEF";
        plist.Add(q);
    }


    return Json(new { rows = plist }, JsonRequestBehavior.AllowGet);

    //return Json("Response from Edit"); 
}
