ajax

普通的ajax應用，結合javascript對html元素的動態操控，結合而成一個優美的效果。

還是用Ajax.net，設定與前篇文章一樣，不再累述。
代碼如下：
163photoTest.aspx.cs
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
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));
    }

    //取資料庫裡的描述
    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]
    //將description儲存進資料庫 www.knowsky.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
        {
            return false;
        }
    }
}
