将Combobox控件添加到datagrideview TextboxColumn单元格 [英] Adding Combobox control to datagrideview TextboxColumn cell

问题描述

您好，我在其中使用窗口应用程序和datagridview DGV填充到数据库表(Patient_name，Test_Name，Result，Reference_Ranges)中.我希望当Result列获得输入焦点时，出现一个组合框，用户从中选择值，但是想要组合框不用于结果列的所有单元格，因为在某些情况下，用户会从键盘输入值，因为组合框是只读的，并且该组合框的数据源已绑定到数据库，并为每个测试选择默认值； br/> 简而言之，我要这样
