两个listbox之间传数据传递

[yangjinju2008]

我现在想实现两个listbox之间传数据，四个按钮就是选中单个，选中全部，删除一个，删除全部 我想用 listA.Items.Add(this.listB.SelectedValue); 最终B的内容要存入数据库，我想对A进行数据绑定，显示值是姓名，实际值是ID，可是我传到B的时候显示却是ID，大家有没有更好的办法啊！ 如果不用数据捆绑话，只显示姓名，可以传到B，但是那是姓名，可能会重复，最好也可以得到ID，和姓名！ 如果我用捆绑，利用listB.SelectedValue再去数据库找姓名觉得数据库访问太频繁了！
谢谢大家了！！！！！！！！
