Question

I have a single form with multiple submit buttons that have same value. Example: “Proceed”.

Now, in ASP.Net MVC’s post controller method, how do I know which button is pressed?

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DepartmentDetails(string submitButton)

The value of submitButton will always be “Proceed”. How do I know which button is pressed.

I have given separate IDs for each button.

Thanks.

Try this:

<% using (Html.BeginForm())
   { %>
   <input type="submit" value="Submit" name="Submit1Button" />
   <input type="submit" value="Submit" name="Submit2Button" />
<%} %>

public class HomeController : Controller
{

    public ActionResult Index()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(FormCollection values)
    {
        string buttonName = values.AllKeys.Where((n) => n.EndsWith("Button")).SingleOrDefault();
        return View();
    }

}
