第二种方式.

不必在另一页中显示带有复选框的gridview，而是将其显示在同一页面中.通过单击gridview中选定项目的添加按钮，您可以将这些项目直接添加到同一页面本身的列表框中.

第三条路.

通过使用Session概念.

您可以将选中的复选框项放入会话中，然后在列表框页面中使用该会话变量.

Second Way.

Instead of displaying gridview with checkbox in another page,display it in same page.By clicking add button for selected items in gridview,you can directly add those items to listbox in the same page itself.

Third Way.

By using Session concept.

you can put the selected check box item in session,then use that session variable in listbox page.
