Question

I am trying to render a simple hyperlink that links to a named anchor within the page, for example:

<a href="#namedAnchor">scroll to down</a>

<a name="namedAnchor">down</a>

The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Test.ascx.cs" Inherits="TestWebApplication1.controls.Test" %>

<a href="#namedAnchor" runat="server">HtmlAnchor</a>

<asp:HyperLink NavigateUrl="#namedAnchor" runat="server">HyperLink</asp:HyperLink>

The generated source looks like:

<a href="controls/#namedAnchor">HtmlAnchor</a>

<a href="controls/#namedAnchor">HyperLink</a>

I really just want:

<a href="#namedAnchor">HtmlAnchor</a>

<a href="#namedAnchor">HyperLink</a>

I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I’m pursuing is not that important enough to justify abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.

Answer 1

Instead of using the NavigateUrl property, just use the href property

<asp:HyperLink href="#namedAnchor" runat="server">HyperLink</asp:HyperLink>
