Xin chào các bạn, bài viết hôm nay mình sẽ tiếp tục hướng dẫn các bạn cách Drag drop dữ liệu giữa hai GridView trên Devexpress C# Winform.

[DEVEXPRESS] How to drag drop two Gridview Winform C#

Ở bài viết này, mình sẽ demo ứng dụng dạng đội hình bóng đá câu lạc bộ PSG (Paris Saint-Germain).

Tại GridView thứ nhất là danh tất cả các cầu thủ của đội bóng

Và GridView thứ hai là mình sẽ chọn ra đội hình thi đấu từ Gridview thứ nhất.
