URL Action including route values

Question

I have an ASP Net MVC 4 app and am using the Url Action helper like this   Url Action  Information    Admin    This page is used for both adding a new and edit an admin profile  The URLs are as follows    Adding a new        http   localhost 4935 Admin Information  Editing Existing    http   localhost 4935 Admin Information 5  lt   Admin ID   When I m in the Editing Existing section of the site and decide that I would like to add a new admin I click on the following link       lt a href   Url Action  Information    Admin    gt Add an Admin lt  a gt    The problem however that the above link is actually going to http   localhost 4935 Admin Information 5  This only happens when I m in that page editing an existing admin  Anywhere else on the site it links correctly to http   localhost 4935 Admin Information  Has anyone else seen this   UPDATE    RouteConfig           routes MapRoute              name   Default               url    controller   action   id                defaults  new   controller    Home   action    Index   id   UrlParameter Optional

outgoing url in mvc generated based on the current routing schema   because your Information action method require id parameter  and your route collection has id of your current requested url  Admin Information 5   id parameter automatically gotten from existing route collection values   to solve this problem you should use UrlParameter Optional     lt a href   Url Action  Information    Admin   new   id   UrlParameter Optional     gt Add an Admin lt  a gt
