ASP.NET MVC return a different view

Question

I have a view which contains a form, the form posts and the data gets processed etc, then I want to return the view Index, so return view("Index");

however this will then complain about my ViewData not existing, I get the feeling that the controller code under Index() isn't being processed which adds the list it requires to the ViewData, anyone know what's wrong?

Thanks

edit: Apparently it's done to prevent recursion.. in which case, I'm lost as to what to do without repeating all my ViewData stuff both Controllers

I think you should have two actions: one that processes the form submission, and another one that collects data for the view. Once the form has been processed, you call return RedirectToAction("Index") and you are done. I hope I understood what you meant by this.

+1 absolutely the way to go, read en.wikipedia.org/wiki/Post/Redirect/Get for more details on benefits of this approach.

how about without redirecting? return View("Index")

@CodeClimber. I have a bit similar scenario. I have a partial view in Index page. Partial view submits the form. on form submission data is stored in database. I want to show the latest data on the Index page. when i tried your approach i get this error "The model item passed into the dictionary is of type 'System.Collections.Generic.List but the dictionary requires a model item of type 'UnderstandingPartialViews.Models.abc'"

@Luckyy, we can redirect to action from one controller to another too, via by RedirectToAction

If your Index method on the controller does a return View("Index"); then just call the Index method with any parameters it requires. Then the method will populate the ViewData reuired by the Index View.
