本文实例讲述了asp.net基于Calendar实现blog日历功能。，具体如下：
怎样用.net的Calendar控件来实现blog中站点日历的效果呢,我们知道站点日历最重要的功能就是,显现在哪天blog主人写了日志,点击日期,你将进入所选日期的日志列表,
首先，我们知道.net中的服务器控件是会进行Postback的，Calendar控件中的第一天在点击时，就会进行一次postback我们要做的就是改变它默认的链接，使它不触发postback事件，其次，就是要知道哪一天有没有日志。至于有没有日志，就要去数据库查询了。
在Calendar中有一个DayRender事件，该事件在呈现每一天时触发，我们可以从这里入手,首先定义一个数组变量:
private int[] arrCurrentDays, arrPreDays, arrNextDays; //三个变量分别是当前月，前一月，和下一个月 private int intCurrentMonth, intPreMonth, intNextMonth; //三个整型数组存放相对月份写有blog的日期
然后在Calendar的DayRender事件中写下如下代码:
CalendarDay d = ((DayRenderEventArgs)e).Day;
TableCell c = ((DayRenderEventArgs)e).Cell;
// 初始化当前月有Blog的日期数组
if (intPreMonth == 0)
{
intPreMonth = d.Date.Month; // 注意：日历控件初始化时我们得到的第一个月并不是当前月，而是前一个月的月份
intCurrentMonth = intPreMonth + 1;
if (intCurrentMonth > 12)
intCurrentMonth = 1;
intNextMonth = intCurrentMonth + 1;
if (intNextMonth > 12)
intNextMonth = 1;
arrPreDays = getArrayDay(d.Date.Year, intPreMonth); //得到前一个月有blog的日期数组
arrCurrentDays = getArrayDay(d.Date.Year, intCurrentMonth);//得到当月有blog的日期数组
arrNextDays = getArrayDay(d.Date.Year, intNextMonth);//得到下个月有blog的日期数组
}
int j = 0;
if (d.Date.Month.Equals(intPreMonth))
{
while (!arrPreDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrPreDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + ">" + d.Date.Day + "</a>"));
}
j++;
}
}
else if (d.Date.Month.Equals(intCurrentMonth))
{
while (!arrCurrentDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrCurrentDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + " title=查看"+d.Date.Day+"日日志>" + d.Date.Day + "</a>"));
}
j++;
}
}
else if (d.Date.Month.Equals(intNextMonth))
{
while (!arrNextDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrNextDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + ">" + d.Date.Day + "</a>"));
}
j++;
}
