Null incoming id in Asp.Net MVC controller action

Question

I have a list of requests(Vr), in this list I created a button to finalize this request(Open Mv).

When I click this button, I am redirected to my Low view, which has its own attributes, plus the Request Id (Vr). This part is working all right, I’m able to click the button, and load the selected object in the downtown view. The problem is in [httpPost], When I click submit, the Request Id is null, and the Low Id comes with the Request Id.

Action get

public ActionResult MvVr(int id)
{
     Vr vrs = new Vr();
     vrs = vrs.BuscarPorIdDaVr(id);
     Mv mv = new Mv();
     mv.Vrs = vrs;
     return View(mv);
}

Action view Only The part that loads the request data

@model Systemsgarage.Models.Mv
