gridview传值有关问题

gridview传值问题
<asp:HyperLink ID="HyperLink1" runat="server"
 NavigateUrl='juBaoXin.aspx?prosecutoredName=<%#Server.UrlEncode(Eval("prosecutoredName").ToString())%> & prosecutoredUnit=<%#Server.UrlEncode(Eval("prosecutoredUnit").ToString())%> &
 prosecutoredPosition=<%#Server.UrlEncode(Eval("prosecutoredPosition").ToString())%> &
 prosecutoredZhiJi=<%#Server.UrlEncode(Eval("prosecutoredZhiJi").ToString())%>'>查看</asp:HyperLink>

web里面我是这样子传值的 gridview里面，但是我判断数据是否为空的时候发现数据没有传过去，不知道怎么改了，肯定各位高手指定一下。先谢谢了

你打开的连接看下juBaoXin.aspx?
