Submitting a form view to controller - asp.net-mvc-3

Question

I have a form in my form view defined as
using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
This form contins a number of input of type button and button
<input type="submit" value="val1" name="action">
<input type="submit" value="val2" name="action">
<input type="submit" value="val3" name="action" />
<button class="button" type="submit" name="action" value="val4">Val4</button>
I have 2 controllers for this view
Public ActionResult form{
}
and
[HttpPost]
public ActionResult form(String button)
{
switch (actionType)
{
case "val1":
return RedirectToAction("AnotherView");
case "val2":
return RedirectToAction("AnotherView2");
default:
return RedirectToAction("AnotherView3");
}
}
But whichever button I click, I am being redirected to the Home defined in the form
using (Html.BeginForm("Index", "Home",
My question is how can I fix this and how can I be certain that this post method is bound to my view as i just typed it in?

Answer 1

using (Html.BeginForm("action_name", "controllername", FormMethod.GET, new { enctype = "multipart/form-data" }))
use input type select:
<select name="action">
<option value="val1" >val1</option>
<option value="val2" >val2</option>
<option value="val3" >val3</option></select>
and method at controller
public ActionResult action_name(String action){
switch (action)
{
case "val1":
return RedirectToAction("AnotherView");
case "val2":
return RedirectToAction("AnotherView2");
default:
return RedirectToAction("AnotherView3");
}
}

Answer 2

If you specify a form field named action MVC will interpret this as the action on the controller to route to. Thus clicking val1 will ultimately execute the method:
public ActionResult val1()
{
}
If this method does not exist, your error handling will take over.
Solution: Don't use action as a name of a form field.
