最近在上软件工程实践课程，想做一个类似于QQ空间或者朋友圈一样的效果。即显示所有好友发送的动态以及动态下回复的信息。
自己YY了一种方法，一开始以为不能达到效果，研究了2个小时终于实现了，感觉效果还是很棒棒的，拿来分享一下。神犇请绕道吧~~
listview可以自己排版布局，我们用listview来显示动态发送者的头像，昵称以及发送时间。
那回复怎么办呢？
gridview的布局与回复较像，效果也比较好。那就用gridview来做回复部分好了。
主要思路就是上图，黑色的由listview显示，红色的回复部分由gridview显示。listview会获取动态信息的ID：<%# Eval("DynamicID") %>，根据这个ID，在gridview中设置好属性，去寻找哪些评论是评论这条动态信息ID的，select出来即可。
效果大约是这样的：
嵌套布局的代码大致是这样子的：
