ASP.NET DetailsView & MySQL (Framework 2.0,3.5) เป็นตัวอย่างบทความการเรียกใช้งาน DetailsView กับฐานข้อมูล MySQL ผ่าน NameSpace ชื่อ MySql.Data.MySqlClient ซึ่งไว้สำหรับจัดการกับฐานข้อมูล MySQL โดยเฉพาะ ในตัวอย่างนี้ผมได้ยกการเขียนร่วมกับ Visual Studio 2005,2008 ซึ่ง Run บน Framework 2.0,3.5 ในรูปแบบของ Code-Behind แยกในส่วนของ Tag และ Code ไว้คนล่ะส่วน และใช้การจัดการ Control ผ่าน Code-Behind ทั้งหมด
Language Code :  VB.NET || C#
