  1.   

    后台代码：
     protected void Button1_Click(object sender, EventArgs e)
        {
            sqlStoredProcedure = "web_sel_fill_tank";
            string[] temps = { TextBox1.Text };
            
            int i = DBHelper.ExecuteCommand1(sqlStoredProcedure, temps);        if (i == 0)
            {
                ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "alert", "alert('查无记录，请重新输入 ！');", true);
            }
            else
            {
                try
                {
                    DBHelper.fillgridview(sqlStoredProcedure, GridView1, temps);
                                }
                catch(Exception ex) 
                {
                    throw ex;
                   //ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "alert", "alert('数据查询出错，请联系管理人员 ！');", true);            }
                finally
                {
                    DBHelper.Connection.Close();
                }
            }
           
              //TextBox2.Text = GridView1.DataKeys[GridView1.SelectedIndex].Value.ToString();         //string parm1 = this.GridView1.DataKeys[e.RowIndex][0].ToString();        //  TextBox2.Text = GridView1.SelectedRow.Cells[0].ToString();
            Label1.Text = DateTime.Now.ToString();
        }

    GridView1.DataKey="字段名"这一句写了吗
