现在困难在于如何添加'lblstrdt'，'lblenddt'和＆amp;的值。 'lblreprtd'到以下超链接

 <asp:HyperLink ID="LabeCR" runat="server" Text='<%# Eval("CR") %>' NavigateUrl='<%# String.Format("~/detailspage.aspx?Rly=CR&Classification={0}", Eval("Classification")) %>'></asp:HyperLink>

以便我可以获取以下查询字符串以在详细信息页面上显示相应的记录

 "~/detailspage.aspx?Rly=CR&Classification=xxxx&strdt=xx/xx/xx&enddt=xx/xx/xx&reprtd=xxxxx"

或者建议另一种方法/代码来获得所需的结果。即使做了大量的谷歌搜索，我也无法找到解决方案。链接到我的网页，其中需要实现此超链接是 - http://elocos.railnet.gov.in/ElectSafety/Elect_CrewAccid.aspx。请帮忙。

Answer 1

试试这个

<asp:HyperLink ID="LabeCR" runat="server" Text='<%# Eval("CR") %>' NavigateUrl='<%# String.Format("~/detailspage.aspx?Rly=CR&Classification={0}&{1}", Eval("Classification"), Request.QueryString.ToString()) %>'></asp:HyperLink>

使用标签值在gridview中进行超链接控制
