(C#) ASP.NET DetailsView Control - GridView Control |
(C#) ASP.NET DetailsView Control - GridView Control ตัวอย่างนี้จะเป็นการใช้งานระหว่าง DetailsView และ GridView โดยให้ GridView ทำการดึงข้อมูงจากฐานข้อมูลออกมาแสดง และมีปุ่มสำหรับการแก้ไข หลังจากคลิกแก้ไขก็จะเป็นหน้าที่ของ DetailView ในการดึงข้อมูลออกมาใส่ใน Form เพื่อรอผู้ใช้ทำการแก้ไขและบันทึกข้อมูล
