Devexpress DetailRow中的按钮需要两个上部嵌套APSxGridView中的键

我有两个嵌套的APSxGridView对象。内部的DetailRow还包含一个按钮。我想初始化按钮，以便它在浏览器中启动新窗口。为此，我需要上GridView中的键id

GridView1
    GridView2
         DetailRow
             Button

我已经知道如何从GridView2获取密钥——我现有的代码如下所示：

protected void btnModify_Init(object sender, EventArgs e)
{
        ASPxButton btn = sender as ASPxButton;
        GridViewDetailRowTemplateContainer clsdetail = btn.Parent as GridViewDetailRowTemplateContainer;

        string partition = "1"; // this should be filled with the GridView1 id
        string cls = clsdetail.KeyValue.ToString(); // this is the GridView2 id

        // The following code just uses the information.
        string panelid = "t" + partition + "-" + cls;

        btn.ClientSideEvents.Click =
            String.Format("function(s, e){{ window.open('producttag.aspx?partition={0}&cls={1}','{2}'); }}",
                partition, cls, panelid);
}

请注意从内部网格中获取密钥的

字符串cls=…

（按钮位于其详细信息行中）

如何获取外部gridview的键？我可以通过父母再做一遍吗？或者还有别的办法吗

更新：可以在内部栅格视图中展开多个详图行。这样，我就无法通过某个隐藏元素传递id。我需要从上面的对象将其设置为按钮级别。

确定。我找到了它--使用

NamingContainer

：

    ASPxButton btn = sender as ASPxButton;
    GridViewDetailRowTemplateContainer clsdetail = btn.NamingContainer as GridViewDetailRowTemplateContainer;
    Control gvClasses = clsdetail.Grid;  // the grid 2
    Debug.Assert(gvClasses.ClientID.EndsWith("gvClasses"));
    GridViewDetailRowTemplateContainer partitionsdetail = gvClasses.NamingContainer as GridViewDetailRowTemplateContainer;
        // the upper is the detail row of the grid 1

    string partition = partitionsdetail.KeyValue.ToString(); // from grid 1
    string cls = clsdetail.KeyValue.ToString();              // from grid 2
