如何从选中的列表框中获取选中的项目 [英] how to get checked items from checked list box

问题描述

嗨！

我有一个表格，其中有两个组合框和一个选中的列表框
c1，c2和check1
c1有10个项目
c2有7个项目
check1有20个项目

现在我要从c1和c2中选择项目以及从check1到sql server中的检查项目

但我不知道如何将选中的项目与选择的项目相关联

我已经做到这里了，但是下一步该怎么做

推荐答案

您必须全部选择它们，还是必须全部选择?循环检查不变的值是没有意义的.如果有一个选定的索引，则您知道该值，则无需循环查找它.

You have to select them all, or in sets ? Looping to check values that don''t change makes no sense. If there''s one selected index, then you know the value, you don''t need to loop to find it.
