我有以下代码，经过测试，效果很好：
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 1; i < 5; i++)
{
var temp = i;
DataTable table = GetTable();
HttpContext.Current.Session[i.ToString()] = table;
GridView gv = new GridView();
gv.ID = "GridView-" + i.ToString();
gv.DataSource = HttpContext.Current.Session[i.ToString()];
gv.DataBind();
Button btn = new Button();
btn.ID = "button-" + i.ToString();
btn.Click += (senders, es) => CreateModalPop(temp,PlaceHolder1, btn.ID);
PlaceHolder1.Controls.Add(gv);
PlaceHolder1.Controls.Add(btn);
}
}
static DataTable GetTable()
{
//
// Here we create a DataTable with four columns.
//
DataTable table = new DataTable();
table.Columns.Add("Dosage", typeof(int));
table.Columns.Add("Drug", typeof(string));
table.Columns.Add("Patient", typeof(string));
table.Columns.Add("Date", typeof(DateTime));
//
// Here we add five DataRows.
//
table.Rows.Add(25, "Indocin", "David", DateTime.Now);
table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
return table;
}
protected void CreateModalPop(int num, PlaceHolder ph, string btnID)
{
GridView gv = new GridView();
gv.ID = "GridViewNew-" + num.ToString();
gv.AutoGenerateColumns = true;
gv.DataSource = HttpContext.Current.Session[num.ToString()];
gv.DataBind();
Panel pn = new Panel();
pn.ID = "Panel-" + num.ToString();
pn.CssClass = "modalPopup";
pn.Controls.Add(gv);
AjaxControlToolkit.ModalPopupExtender modalPop = new AjaxControlToolkit.ModalPopupExtender();
modalPop.ID = "ModalPopup-1";
modalPop.PopupControlID = pn.ID;
modalPop.TargetControlID = btnID;
modalPop.BackgroundCssClass = "modalBackground";
// Adding modalpop to panel
pn.Controls.Add(modalPop);
// Adding Panel to placeholder
ph.Controls.Add(pn);
modalPop.Show();
}
}

现在我接受了这段代码，并尝试将它放在一个类中，然后使用该类。执行此操作后，表格会在页面加载时加载，但是当您单击其中一个按钮时，它会将您带到一个空白页面。为什么这样做？或者我该如何解决？
