(Tạo Modal Popup trong Asp.net) - Trong bài viết này, thủ thuật tin học sẽ hướng dẫn các bạn cách sử dụng ASP.Net AJAX Control Toolkit ModalPopupExtender kết hợp với các thuộc tính css của bootstrap để tạo Popup trong asp.net. Popup này sẽ có chức năng thêm, sửa dữ liệu một cách nhanh chóng, thuận tiện và dễ dàng. Sau khi thực hiện xong các thao tác thêm, sửa dữ liệu sẽ được hiển thị ngay tức thì lên Gridview.
