ASP.NET MVC2 - Return to previous View from a controller action

How can I return to the "previous" view from an action in 开发者_JAVA百科the controller ?

I have an action that can be reached from 2 different views.

The action can result in 2 ways:

Success - and then I return to 3rd different view Failure - and then I want to return to the previous view (one of the 2) - having the same (old) model data with a TempData["Message"] containing the error.

I want to return to the view that posted to this action - How can I achieve this behavior ?

You can pass previous view name as a parameter to your action.

public ActionResult Edit(DataObject model, string prevAction)
{
    if (model.IsValid)
    {
        return View("SomeView");
    }
    else
    {
        return RedirectToAction(prevAction, new { data = model });
    }
}

You could have a query string variable that holds the location to where you would like to return.

Something like controller/action?returnUrl=original/route
