同一页面内的不同内容加载
网站的一个基本功能，即在一个页面内加载不同的内容，如某一页的
URL：****.aspx？PostID={0}
如.net   2.0   GridView中的HyperLinkField就有
DataNavigateUrlFormatString= "ShowNews.aspx?PostID={0} "的属性
页面内容的加载是怎样实现的，能不能给举个例子？



------解决方案--------------------

if
page A DataNavigateUrlFormatString= "ShowNews.aspx?id=1 "
page B get 内容 where id = 1

if
page A DataNavigateUrlFormatString= "ShowNews.aspx?id=2 "
page B get 内容 where id = 2

<asp:HyperLinkField DataTextField= "AgentName " HeaderText= "代理名称 " DataNavigateUrlFields= "Agentid " DataNavigateUrlFormatString= "song.aspx?id={0} " />

可以看出DataNavigateUrlFields是超链接可能会使用到的数据字段的字段名称，一般他会配合
DataNavigateUrlFormatString或者NavigateUrl这个来使用
如果DataNavigateUrlFields中有多个字段,在需要第一个字段时使用{0}, 第二个字段使用{1},以此类推.
