Tìm kiếm dữ liệu sử dụng AJAX Modal Popup Extender trong ASP.Net

(Tìm kiếm với Modal Popup trong Asp.net) – Trong các Form nhập dữ liệu, để tìm kiếm và chọn nhanh thông tin từ bảng dữ liệu khác, các lập trình viên thường sử dụng 1 trong 2 cách đó là: Autocomplete hoặc Popup. Mỗi cách sử dụng có những ưu nhược điểm khác nhau, với Autocomplete người sử dụng không phải mất thêm nhiều thao tác kích để chọn dữ liệu, nhưng với dữ liệu có nhiều tiêu chí để tìm thì phải sử dụng Popup. Với Popup người sử dụng sẽ mất thêm thao tác nhưng khi cần nhiều tiêu chí để tìm kiếm chính xác dữ liệu thì Popup sẽ giúp người lập trình giải quyết được vấn đề này. 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 tìm kiếm dữ liệu một cách nhanh chóng, thuận tiện và dễ dàng.
