在目前的情况下不存在

我有低于code：

code背后：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.DataVisualization.Charting;

namespace TestApp2
{
    public partial class hookload : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (Request.QueryString["Rig_ID"].Equals(1))
                MultiView1.ActiveViewIndex = 0;
            else if (Request.QueryString["Rig_ID"].Equals(2))
                MultiView1.ActiveViewIndex = 1;
            else if (Request.QueryString["Rig_ID"].Equals(3))
                MultiView1.ActiveViewIndex = 2;
            else if (Request.QueryString["Rig_ID"].Equals(4))
                MultiView1.ActiveViewIndex = 3;
            else if (Request.QueryString["Rig_ID"].Equals(5))
                MultiView1.ActiveViewIndex = 4;
        }
    }
}

这是我的aspx文件：

现在我的问题是，当我尝试运行此，我得到的消息MultiView1'名称''不在当前情况下存在。我真的不明白，为什么我收到此错误，但我也是一个小白所以这并不奇怪。 :)基本上，我有一个ASP：GridView控件表的第一页上，我试图传递参数，然后通过这个网页进行处理，所以当有人点击链接〜\\图\\ hookload.aspx Rig_ID = 2，它处理？多视图索引1，使其显示由SQL查询所描述的相关数据图表。

Now my problem is that when I try to run this, I get the message 'The name 'MultiView1' does not exist in the current context'. I really don't understand why I am getting this error, but I am also a noob so it isn't surprising. :) Basically, I have a asp:gridview table on the first page and I am trying to pass parameters to then be processed by this page so when someone clicks the link for ~\charts\hookload.aspx?Rig_ID=2, it processes MultiView Index 1 so it displays a chart of relevant data as described by the SQL Query.

这一直是我发现到目前为止，要做到这一点，所以如果其他人有一个更好的主意的唯一途径，相信我，我洗耳恭听。我一直在努力找到一个答案，主要是因为我不知道什么搜索关键字。任何帮助将是AP preciated。

This has been the only way I have found so far to do this so if anyone else has a better idea, believe me I am all ears. I have struggled to locate an answer to this, mainly because I don't know what keywords to search for. Any help would be appreciated.
