刚学ASP。NET，遇到一个例子的问题，没有出错提示，但是没出现预想的程序效果。
程序的功能是实现显示一个日历的事件。
具体为：
1、第一次打开，本月日期背景和字体颜色区别于上一月和下一月，每个日期数字下显示对应的事件短标题。
2、每点击一个日期，最下方就显示这个事件的详细信息。
现在只显示一个日期控件，后台代码写了很多却等于什么都没写。
代码如下：
数据源文件MyCalendar.xml:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<MyCalendar>
<Event>
<ShortDesc>事件1</ShortDesc>
<DetailDesc>事件1的详细描述，可以有很多的内容.</DetailDesc>
<EventDate>2006-10-1</EventDate>
<StartTime>6:00 PM</StartTime>
<EndTime>11:00 PM</EndTime>
</Event>
<Event>
<ShortDesc>事件2</ShortDesc>
<DetailDesc>事件2的详细描述，可以有很多的内容，也可以有自己的描述．</DetailDesc>
<EventDate>2006-10-7</EventDate>
<StartTime>3:30 PM</StartTime>
<EndTime>6:30 PM</EndTime>
</Event>
<Event>
<ShortDesc>事件3</ShortDesc>
<DetailDesc>事件3的详细描述，可以有很多的内容，也可以有自己的描述和内容．</DetailDesc>
<EventDate>2006-10-15</EventDate>
<StartTime>8:30 PM</StartTime>
<EndTime>14:10 PM</EndTime>
</Event>
</MyCalendar>
