Create ASP.NET Dynamic Hyperlinks from URLs Stored in Web.Config

Consider storing any URLs used by your application in the web.config file—where you can easily update them—and then using them to create hyperlinks in your web site dynamically. To do that, you need to decide exactly how to store and retrieve the URLs. Here's one method.

In the web.config file, create an entry like the one shown below:

<appSettings>
  <add key="someurl" value="http://www.devx.com" />
</appSettings>

To read this entry from the web.config file, use AppSettings and the key attribute value of the entry, for example:

<asp:HyperLink ID="HyperLink1" runat="server"
   NavigateUrl="<%$ Appsettings:someurl %>"  Text="Devx">
</asp:HyperLink>
