无法从html上的文本框中获取参数

Question

Hi im working right now on a page where you input the id of a person, and if its not in the system then it sends you to the Create , so you can register. However

[HttpPost]
public ActionResult ingresarSolicitante(int? id)

doesn't get the id, even if I change it for a string and a textbox, I cannot get the value. Any ideas?

here is the html

@model Entrega02Programacion03.Models.Solicitante
@{
    ViewBag.Title = "ingresarSolicitante";
}

<h2>ingresarSolicitante</h2>

<div>

    @using (Html.BeginForm())
    {
        <p>
            Buscar Solicitante por celuda: @Html.TextBox("Cedula")<br />
            <input type="submit" value="Filtrar" />
        </p>
    }

</div>

and here is the code on the controller

[HttpPost]
public ActionResult ingresarSolicitante(string id)
{     
    // busco el solicitante
    Solicitante solicitante = db.Solicitante.Find(id);
    //si exite voy a crear expediente
    if (solicitante != null) 
    {
        TempData["solicitante"] = solicitante;
        return RedirectToAction("InformeSolicitante");
    }
    // si no me redirije a crear solicitante
    else
    {
        return RedirectToAction("Create");
    }

}

// GET: Solicitantes/Edit/5
public ActionResult Edit(int? id)
{
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    Solicitante solicitante = db.Solicitante.Find(id);
    if (solicitante == null)
    {
        return HttpNotFound();
    }
    return View(solicitante);
}

I dont know whats wrong with the string id on this method that I allways get a null.

Answer 1

change textbox name @Html.TextBox("Cedula") to @Html.TextBox("id")

or change the parameter name of your action method to Cedula

Answer 2

Your Html Page is PageModelBase and you can get your Id from this. Or in other word put that id into the TextBox like:

@model Entrega02Programacion03.Models.Solicitante
@{
    ViewBag.Title = "ingresarSolicitante";
 }

 <h2>ingresarSolicitante</h2>

 <div>

@using (Html.BeginForm())
{
    <p>
        Buscar Solicitante por celuda: @Html.TextBox(Model.Id)<br />
        <input type="submit" value="Filtrar" />
    </p>
}

If you do this, you can set and get data from HTML and into HTML
