Lambda Based RedirectToAction Sample Updated to MVC Preview 3

May 29, 2008 18:44 by matthaw

I took my Lambda based RedirectToAction solution I previously blogged about and updated it to work against the Preview 3 bits. I also took the liberty to fix the bug where you couldn't actually call another controller's action. Some notable changes in the source, is that ActionRedirectResult is no more - as it's replaced with RedirectToRouteResult. I think this was a good consolidation between RedirectToAction and RedirectToRoute since they basically do exactly the same thing. You'll also notice that there are 3 more extension methods, which was necessary to fix the prior bug. Now, you can write code like

   1:  // for actions off of the current controller

   2:  return this.RedirectToAction(c => c.Login());

   3:  return this.RedirectToAction(c => c.Login("matt"));

4:

   5:  // alternatively, within the UserController you can do the following

   6:  return this.RedirectToAction<ProductController>(c => c.View(102));

I'm not going to post the entire code sample as you can download it here. Enjoy it, and let me know of anything else you'd like to see.

Not only did this fix my problem calling another controller's action, but it fixed my problem where my session variable was being destroyed. Much obliged!

Nice job, this is great. I removed the (this) extension bits and just added it to my base controller class overloading RedirectToAction since it doesn't have any conflicting <T> methods and the signatures are unique. Works like a charm, and is much cleaner. I hope they add this into the core MVC eventually.

Building off of this example, I suppose we can also do this...

<%= Html.ActionLink<ProductController>(c => c.View(102)) %>

I almost started to build it myself, good job. Hopefully it will be added to the MVC core.
