外網(wǎng)使用winform應(yīng)用程序 winform下拉框控件叫什么

生活百科

一直以來winform的listview都只是作為數(shù)據(jù)輸出顯示來用, 想要實現(xiàn)數(shù)據(jù)的雙向操作比較難
之前都需要用其他表格類控件實現(xiàn)這個雙擊編輯文本,雙擊實現(xiàn)下拉列表框選擇文本功能, 而且其中有很大一部分是ocx組件,
那么就需要在客戶電腦上regsvr32 注冊它, 這樣就需要管理員權(quán)限, 這樣操作并不是很好,
于是考慮著手動改造listview使其滿足我的需求.
還好, aardio范例里有個數(shù)據(jù)視圖win.ui.grid的庫可供參考, 我就是根據(jù)這個庫內(nèi)的實現(xiàn)方法來升級改造的.
下面我在原listview grid基礎(chǔ)上增加了, 雙擊指定列 可直接編輯文本 / 彈出下拉框選擇文本 功能.
