GridView和DetailsView配合使用遇到的问题
尝试做了个GridView和DetailsView联动的页面，点击GridView的“选取”，就可以出现DetailsView的界面：下面是代码，我遇到了两个问题：
问题1：我修改了DetailsView后，GridView的数据不能即时显示更新后的效果，也就是DetailsView上修改了数据，GridView还是显示老数据，要下一次打开GridView才能显示更新后的效果。
问题2：DetailsView每次都是从页面的顶部出现，实在不方便。我想改造成能在当前页面弹出一个DetailsView窗口，当我在这个DetailsView窗口更新完数据后，点击DetailsView最下面的“更新”或“删除”键，便能保存结果并关闭DetailsView窗口。这个这个功能对于我来说太难了，完全不知道从何入手！
我是菜鸟，请各位帮忙看看！谢谢

--------------------编程问答-------------------- 你如果想要实现在当前页面弹出一个DetailsView窗口， 要用js实现，或者根据情况显示出一个div, 放置一个detailsview在div中，根据情况显示出来，或者使用window.open打开一个新窗口，控制它的大小和显示位置 --------------------编程问答-------------------- 问题1：给DetailsView增加事件
