how can i get the text box for a view? in my controller - asp.net-mvc

Question

I follow this example to make n to n relations
http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/updating-related-data-with-the-entity-framework-in-an-asp-net-mvc-application
it work fine but for the n to n relations with payload to the database i figure out and I can do the [HttpGet] and show the view what i want to show but now i want to know how can i get the textbox I have in my view, I can get the checkbox in my controller (see see below the action) and this is my view so my question will be how can get the textbox too? in my controller for every checkbox?
#using (Html.BeginForm("AgregarEmpresas", "Empleado"))
{
<fieldset>
<div class="editor-field">
<table>
<tr>
#{
int cnt = 0;
List<ITCOrganigrama.ViewModel.AsignarEmpresa> empresas = ViewBag.Empresas;
foreach (var empresa in empresas)
{
if (cnt++ % 5 == 0) {
#: </tr> <tr>
}
#: <td>
<input type="checkbox"
name="selectedEmpresa"
value="#empresa.EmpresaId"
#(Html.Raw(empresa.Assigned ? "checked=\"checked\"" : "")) />
#empresa.Nombre
<div>
#Html.LabelFor(model => empresa.cargo)
#Html.TextBoxFor(model => empresa.cargo, new { style = "width: 150px;" })
#Html.ValidationMessageFor(model => empresa.cargo)
</div>
#:</td>
}
#: </tr>
}
</table>
</div>
<p>
<input type="submit" value="Agregar" />
</p>
</fieldset>
}
the action where i get the chekbox
[HttpPost]
public ActionResult AgregarEmpresas(int? id, FormCollection formCollection, string[] selectedEmpresa)
{
}
my final view:

public bool Assigned { get; set; }
}

Look at your post action and it's parameters. Names of those are really important.
Your checkboxes
<input type="checkbox"
name="selectedEmpresa"
value="#empresa.EmpresaId"
are working fine beacuse look at the name of the input its "selectedEmpresa" it's the same name as in Controller Action definition. Model binder looks for this name in posted data and if he finds it, he creates object from it. In your case he will try to parse data into string[] object.
So ... first of all you have to change action definition to something like.
[HttpPost]
public ActionResult AgregarEmpresas(int? id, FormCollection formCollection, string[] selectedEmpresa,string [] empresaTextBox)
{
}
Then you have to change generated html.
#Html.TextBoxFor(model => empresa.cargo, new { style = "width: 150px;", name="empresaTextBox" })
With those changes you should get some data inside Action. However you will get something weird beacuse you have multiple checkboxes and textboxes in order to tell model binder that there are multiple elements of those you have to prepare special name of inputs that contains index number.
Look at this example
<input name="childs[0]"></input>
<input name="childs[1]"></input>
In this case Model Binder will create array of objects that contains 2 of them.
So finally your code would have to look like this.
#using (Html.BeginForm("AgregarEmpresas", "Empleado"))
{
<fieldset>
<div class="editor-field">
<table>
<tr>
#{
int cnt = 0;
int i=0;
List<ITCOrganigrama.ViewModel.AsignarEmpresa> empresas = ViewBag.Empresas;
foreach (var empresa in empresas)
{
if (cnt++ % 5 == 0) {
#: </tr> <tr>
}
#: <td>
<input type="checkbox"
name="selectedEmpresa[#i]"
value="#empresa.EmpresaId"
#(Html.Raw(empresa.Assigned ? "checked=\"checked\"" : "")) />
#empresa.Nombre
<div>
#Html.LabelFor(model => empresa.cargo)
#Html.TextBoxFor(model => empresa.cargo, new { style = "width: 150px;" ,name=String.Format("empresaTextBox\[{0}\]",i) })
#Html.ValidationMessageFor(model => empresa.cargo)
</div>
#:</td>
i++;
}
#: </tr>
}
</table>
</div>
<p>
<input type="submit" value="Agregar" />
</p>
</fieldset>
}
If you will get this to work. Then i would try to create a class with one boolean and one string value. With this change you would operate on the array of classes instead of two arrays with strings.
