Html.BeginForm() with only form Id is not generating correct action url

asp.net-mvc-4, c#, html.beginform

Solution

When you are trying to generate a route, such as with `BeginForm`, MVC will do its best to include things that you might need.

If you're at `domain.com/Home/Index/b9f88f80-f31f-4144-9066-55384c9f1cfc` and you use the code that you have provided than the form will be generated with the action, controller and route values as it finds them.

controller / action / id
/Home      / Index  / b9f88f80-f31f-4144-9066-55384c9f1cfc

One way to get around this is to force id to be nothing (such as an empty string).

Observe:

@using (Html.BeginForm(null, null, new { @id = string.Empty },
    FormMethod.Post, new { @id = "Id" }))
{

}

The `new { @id = string.Empty }` is an anonymous object that represents the route values.

Problem

I only want to add the formId in the `beginForm()` If i try using `Html.BeginForm(null, null, FormMethod.Post, new {@id="Id"})` then the Html generated is `<form action="/newquestion/payment/b9f88f80-f31f-4144-9066-55384c9f1cfc" ... >` i don't know how that action url is generated so i tried, `Html.BeginForm(new {@id="Id"})` but then the action url looks like this `<form action="/newquestion/payment/Id... >` In both the cases the action url is not what it should be and it is not hitting the post action of the controller.
