推荐答案

添加HTML按钮并通过Java脚本删除所选文档

Add a HTML button and remove the selected document through java script

您的删除按钮正在回发页面，这就是您丢失最后一页状态的原因.
一种简单的解决方案是使用视图状态恢复到最后一个状态.
我认为最好的解决方案是停止回发.而是使用ajax来满足这种情况.

有关视图状态的更多详细信息，请查看kb文章，

Your delete button is doing a postback to the page and that is the reason, you lost the last page state.

One simple solution is to use view state to regain to the last state.
The best solution, I see is stop doing postback. Instead use ajax to cater this situation.
