推荐答案
必须在页面的每个帖子上重新创建动态控件，不仅仅是第一次创建！
当你点击网格上的一个按钮时，点击会启动回发到服务器，但在那个流程中你不会创建动态控件，所以它从页面中消失...
如果你学习使用AJAX，你可以节省大量的工作和网络使用...
A dynamic control must be re-created on each and every post to the page, not only on the first creation!
When you hit one of your buttons on the grid, the click initiates a post-back to the server, but in that flow you do not create your dynamic control so it disappears from the page...
You can save yourself a lot of work and network usage if you learn using AJAX...
