Binding ASP.Net Web.Config Settings To .ASPX File ?

Question

The Scenario

I have an ASP.NET web project. I want to be able to define all of the links for the site inside my web.config file so that they can be changed easily if needs be. Currently I have an "" section in my web.config file.

The Question

How do I bind this key value pair to an '' tag in my .aspx file?!

The App Settings in My Web.Config File

<appSettings>
    <add key="MyNewLink" value="http://someurl.co.uk/" />
</appSettings>

Help greatly appreciated.

EDIT:

Sorry I should have mentioned that this is for a html link: **<a href></a>**

In your aspx file it would be:

NavigateUrl='<%$ AppSettings:MyNewLink %>'

and the full <a> tag is defined as:

<a runat="server" href="<%$ AppSettings:MyNewLink %>">Text link</a>

This syntax can only be used on an ASP.NET WebForms server control.

This fails...... ###Error Message: Literal expressions like '<%$ AppSettings:MyNewLink %>' are not allowed. Use instead. – Goober Oct 13 '09 at 11:19
This definitely works: Text link – Locksfree Oct 13 '09 at 12:04
Well you learn something new every day, I didn't know you could do that! Thanks @Locksfree – DavidGouge Oct 15 '09 at 11:19

Isn't this what a .sitemap file is for?

Anyway, as far as I know, you will have to 'bind' this from code behind. Something like:

hlYourLink.NavigateUrl = ConfigurationManager.AppSettings["MyNewLink"];

so i would have to give the an ID attribute called 'h1YourLink'? – Goober Oct 13 '09 at 11:20
And a runat="server" .. But the above solution Locksfree provided should work. – Moulde Oct 13 '09 at 11:57
Oh, and you should use the asp:hyperlink control, because the a tag doesn't have a property called navigateurl – Moulde Oct 13 '09 at 12:02

I ended up using this......

.aspx file

<asp:literal id="litgetquote" runat="server"></asp:literal>

.aspx.cs CODE BEHIND

litgetquote.Text = "<A HREF='" + ConfigurationManager.AppSettings["GetQuoteUrl"] + "'>" +
            "get a quote now" + "</A>";

you should consider using this for readability: litgetquote.Text = string.Format("get a quote now", ConfigurationManager.AppSettings["GetQuoteUrl"]); – Pete Amundson Jul 23 '10 at 18:47
I believe all you needed was runat='server' in your element. – deebs Jul 13 '17 at 13:56
