文檔簡介

1、使用 DevExpress 控件結合 js 來進行數(shù)據(jù)展示層和校驗層的操作邏輯進行相關數(shù)據(jù)操作圖：我們在實現(xiàn)文件上傳到數(shù)據(jù)庫的時候，都需要通過相關的上 傳控件進行，一般的上傳控件我們需要在后臺進行數(shù)據(jù)轉換 成二進制數(shù)組。由于上傳控件是使用 js 上傳，所以很難通過 異步來實現(xiàn)上傳 (當然優(yōu)秀的 Jquery 和定制的可以 )。這里通 過 dev 控件中的 Uploadcontrol 捕捉到 uploadcomplete 事件， 直接得到二進制數(shù)組，并將其存入session (由于比較大，在上傳入數(shù)據(jù)庫后，我們最好將session 清空)。aspx:<dxuc:ASPxUpload
