  普通的ajax应用结合javascript对html元素的动态操控结合而成一个优美的效果

  还是用Ajax.net,设置与前篇文章一样,不再累述
  代码如下:
  163photoTest.aspx.cs
  using System;
  using System.Data;
  using System.Configuration;
  using System.Collections;
  using System.Web;

  using System.Web.UI.WebControls.WebParts;
  using System.Web.UI.HtmlControls;
  using System.Data.SqlClient;

  public partial class _163photoTest : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e)
      {
          description.Text  = GetDescription();
          AjaxPro.Utility.RegisterTypeForAjax(typeof(_163photoTest));
      }

      //取数据库里的描述
      protected string GetDescription()
      {
          try
          {
              string strComm = "select  photo_description from tab_photo where photo_id=1";
              SqlConnection myConn = new SqlConnection("user id=sa;password=123;Database =test;data source=z;");
              myConn.Open();
              SqlCommand myComm = new SqlCommand(strComm, myConn);
              SqlDataReader myReader = myComm.ExecuteReader();
              myReader.Read();
              return myReader.GetString(0);
          }
          catch
          {
              return "";
          }
      }

      [AjaxPro.AjaxMethod]
      //将description保存进数据库 school.cnd8.com
      public bool UpdateDesc(string description)
      {
          try
          {
              string strComm = "update tab_photo set photo_description='" + description + "' where photo_id=1";
              SqlConnection myConn = new SqlConnection("user id=sa;password=123;Database =test;data source=z;");
              myConn.Open();
              SqlCommand myComm = new SqlCommand(strComm, myConn);
              myComm.ExecuteNonQuery();
              return true;
          }
          catch
