存在我有下面的代碼：難道不是在目前情況下
後面的代碼：
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;
}
}
}
這是我的aspx文件：

現在我的問題是，當我試着運行這個，我得到'The name'MultiView1'在當前上下文中不存在'的消息。我真的不明白爲什麼我會得到這個錯誤，但我也是一個小菜鳥，所以這並不奇怪。 :)基本上，我在第一頁上有一個asp：gridview表，我試圖傳遞參數，然後由這個頁面處理，所以當有人點擊鏈接〜\ charts \ hookload.aspx？Rig_ID = 2時，它會處理MultiView Index 1，因此它顯示了SQL查詢描述的相關數據圖表。
這是迄今爲止我發現的唯一途徑，因此如果其他人有更好的主意，請相信我，我都是耳朵。我一直在努力尋找答案，主要是因爲我不知道要搜索什麼關鍵字。任何幫助，將不勝感激。
就是這樣，謝謝！ Aravind，你也是。 – Trido
