我有一个gridview显示出来一个数据库的内容（包括姓名列，年龄列，省份列），每行内容都加了一个checkbox。每当我选中某一行的checkbox，则
在gridview外面的一个小区域（比如一个叫SelectedItem的div）显示我选择的一个的姓名。我又选择一个checkbox,则SelectedItem里面又添加一个姓名，排列方式为一行一行的；反之，如果我把某个选择的checkbox不选了，则这个SelectedItem里面的姓名列表就自动删除我不选择的那个姓名。
这个怎么实现？SelectedItem里面需要使用什么控件啊？
（提醒，我觉得我还是不使用js了，使用checkbox的select_change方法，然后对SelectedItem进行动态修改。所以，我不知道SelectedItem里面使用什么控件，该怎么运作）
我说的是否明白？多谢。
