ASP MVC2 Calling different views - asp.net

Question

Hello fellow programmers!
I am currently stuck in a school assignment. I am working with ASP.NET, MVC2 (I know, it's old :( ) Here is the situation: I have a controller who will decide with an if statement what view to return. For example:
Here is a method within my controller:
public ActionResult Verification()
{
String lastName = Request["lastName"];
String name = Request["name"];
String dob = Request["dob"];
String phone = Request["phone"];
String selection = Request["selection"];
Verification verifying = new Verification(lastName, name, dob, phone, selection);
String other = verifying.returnIfGood();
if (!(other == ""))
{
return RedirectToAction("probleme1");
}
else
{
return RedirectToAction("probleme2");
}
}
RedirectToAction seem to point directly at a view, but I also need to pass the view a string to work with. I also noticed if I call a method within my controller, no view gets returned, which I am a little confused about. I am trying to stay away from ajax and jquery since I haven't seen those yet. Is there any way to do this using only c#?

Answer 1

Here you need to ajax call with query string like
Controller/action?viewname='abc'
Then
Get on actionresult method
Then redirect to action on the basis of viewName.
Or
Redirect(controller/actionName)

Your question is quite confusing as to what you're trying to accomplish, and some of the comments seem to indicate a misunderstanding of what is actually going on. Given that, I'm going to try to address your question but may be missing the mark.
RedirectToAction does not "point directly at a view". It causes an HTTP 302 response to be sent to the browser with a new URL which the browser then turns around and requests with a new GET operation.
Given that you haven't provided the code for the probleme1 and probleme2 action methods I have no idea what other logic might live there. If all they do is return a view you could rewrite your Verification method to return the view instead and include the "string to work with" as a model.
public ActionResult Verification()
{
// code omitted for brevity...
if (!(other == ""))
{
return View("probleme1", "some string");
}
else
{
return View("probleme2", "some other string");
}
}
If the logic in probleme1 and probleme2 is more complex and you really need to preserve the RedirectToAction approach you could set a value in TempData in your Verification method and then pass that value along in the other methods.
public ActionResult Verification()
{
// code omitted for brevity...
if (!(other == ""))
{
TempData.ModelString = "some string";
return RedirectToAction("probleme1");
}
else
{
TempData.ModelString = "some other string";
return RedirectToAction("probleme2");
}
}
public ActionResult probleme1()
{
return View(<view name>, TempData.ModelString);
}
In this case you need to use TempData and not ViewData as the former will survive the redirect while the latter will not. Put another way, TempData is for holding information between controller actions during a redirect, ViewData is for sending information from the controller to the view.
