代码很简单，这里就不累赘了。看代码如下：

<%@ Page Language="C#" AutoEventWireup="true" %>

<script runat="server">
  // 计算数据，完全可以从数据看取得
  ICollection CreateDataSource()
  {
    System.Data.DataTable dt = new System.Data.DataTable();
    System.Data.DataRow dr;
    dt.Columns.Add(new System.Data.DataColumn("序号", typeof(System.String)));
    dt.Columns.Add(new System.Data.DataColumn("学生姓名", typeof(System.String)));
    dt.Columns.Add(new System.Data.DataColumn("语文", typeof(System.Decimal)));
    dt.Columns.Add(new System.Data.DataColumn("数学", typeof(System.Decimal)));
    dt.Columns.Add(new System.Data.DataColumn("英语", typeof(System.Decimal)));
    dt.Columns.Add(new System.Data.DataColumn("计算机", typeof(System.Decimal)));

    for (int i = 0; i < 8; i++)
    {
      System.Random rd = new System.Random(Environment.TickCount * i); ;
      dr = dt.NewRow();
      dr[0] = i.ToString();
      dr[1] = "【孟子E章】" + i.ToString();
      dr[2] = System.Math.Round(rd.NextDouble() * 100, 2);
      dr[3] = System.Math.Round(rd.NextDouble() * 100, 2);
      dr[4] = System.Math.Round(rd.NextDouble() * 100, 2);
      dr[5] = System.Math.Round(rd.NextDouble() * 100, 2);
      dt.Rows.Add(dr);
    }
    System.Data.DataView dv = new System.Data.DataView(dt);
    return dv;
  }

  protected void Page_Load(object sender, EventArgs e)
  {
    if (!IsPostBack)
    {

      GridView2.DataSource = GridView1.DataSource = CreateDataSource();
      GridView2.DataBind();
      GridView1.DataBind();
    }
  }

  protected void Button1_Click(object sender, EventArgs e)
  {
    Ret1.Text = "";
    foreach (GridViewRow gvr in GridView1.Rows)
    {
      CheckBox ch = (CheckBox)gvr.FindControl("ItemCheckBox");
      if (ch.Checked)
      {
        Ret1.Text += "<li>GridView1 您选择的是（键值）：" + GridView1.DataKeys[gvr.DataItemIndex].Value.ToString();
      }
    }
  }

  protected void Button2_Click(object sender, EventArgs e)
  {
    Ret2.Text = "";
    foreach (GridViewRow gvr in GridView2.Rows)
    {
      CheckBox ch = (CheckBox)gvr.FindControl("ItemCheckBox");
      if (ch.Checked)
      {
        Ret2.Text += "<li>GridView2 您选择的是（键值）：" + GridView2.DataKeys[gvr.DataItemIndex].Value.ToString();
      }
    }
  }

  protected void CheckAll(object sender, EventArgs e)
  {
    CheckBox cbx = (CheckBox)sender;
    foreach (GridViewRow gvr in GridView1.Rows)
    {
      CheckBox ch = (CheckBox)gvr.FindControl("ItemCheckBox");
      ch.Checked = cbx.Checked;
    }
