How to conditional Redirect using HTML <a> tag depending on QueryString Value in asp.net?

问题

I am redirecting to Teammember.aspx page with javascript from code behind.

teammember.Attributes.Add("onclick", "window.location.href='TeamMemberDetails.aspx?Id=" + Id + "'" + "&isabout=true");

When coming on TeamMemberDetails.aspx page i have an anchor tag:

 <a style="border: 0px none; float: left;" href="TeamMember.aspx">
    <img alt="<--" src="Images/ArrowLeft.png" style="display: inline-block; cursor: pointer;border: 0 none;" />
 </a>

Now, Depending on Querystring parameter i.e isabout the page must redirect. if isabout=true then it must redirect to Memberlist.aspx page else other.aspx page using HTML Anchor Tag (Conditional Redirect)

回答1:

put runat="server" attribute and find anchor tag in code behind.

  <a id="lnktoRedirect" runat="server">Redirect</a>

Code behind:

 if (isabout)
 {
       lnktoRedirect.HRef = "Memberlist.aspx";
 }
 else
 {
       lnktoRedirect.HRef = "other.aspx";
 }
