You can do that by calling an action method on controller either by AJAX or form post, as simple as it is

Or i did not understand your question, can you please elaborate?

You need a form in your cshtml, and a parameter on your controller to receive the model. I usually use specially designed formmodels:

public class ProductFormModel
    {
        [ScaffoldColumn(false)]
        public int ProductId { get; set; }
        [Required, Display(Name = "Product")]
        public string ProductName { get; set; }
    }

Then the contoller will accept a ProductFormModel as a parameter:

[HttpPost]
public ActionResult Create(ProductFormModel model){
    if(ModelState.IsValid){
        //etc
    }
}

Hi,

The sample below is sending a model "PersonInfo" from Index.cshtml send to StudentController, received on HttpGet "create" send it to view create.cshtml.

Here my Sender View send an object named "item":

@foreach (var item in Model)
    {
        <tr>
            <td>@Html.DisplayFor(modelItem => item.FullName)</td>
            <td>@Html.DisplayFor(modelItem => item.CategoryName)</td>
            <td>@Html.DisplayFor(modelItem => item.BirthDate)</td>
            <td>@Html.DisplayFor(modelItem => item.NationalIDNumber)</td>
            <td>@Html.DisplayFor(modelItem => item.AddressLine1)</td>
            <td>@Html.DisplayFor(modelItem => item.City)</td>
            <td style="padding-left: 15px">
                @Html.ActionLink("Student", "Create", "Student", item, null) |
                @Html.ActionLink("Instructor", "Create", "Instructor", item, null)
            </td>
        </tr>
    }

Here my controller receive the "item" named "PersonInfo personInfo", and send ViewData.Model and ViewBag.FullName:

        // GET: /Student/Create
        public ActionResult Create(PersonInfo personInfo)
        {
            if (personInfo != null)
            {
                ViewBag.FullName = personInfo.FullName;
                CoursePerson student = new CoursePerson();
                student.PersonID = personInfo.BusinessEntityID;
                student.EnrollmentDate = DateTime.Now;
                student.Discriminator = "Student";
                ViewData.Model = student;
            }
            return View();
        }

Here my receiver view as "model" from "ViewData.Model" and @ViewBag.FullName

@model CourseCenter.Models.CoursePerson

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")"></script>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Student</legend>

        @Html.HiddenFor(model => model.PersonID)
        @Html.HiddenFor(model => model.Discriminator)

        <div class="editor-label">
            @Html.LabelFor(model => model.PersonInfo.FullName)  @ViewBag.FullName
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.EnrollmentDate)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.EnrollmentDate)
            @Html.ValidationMessageFor(model => model.EnrollmentDate)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

Hope this can help.

@Html.ValidationSummary(true)
<fieldset>
<legend>Editar Companias</legend>

<table align="center" style="background-color:White">

<tr>

<td>
@Html.LabelFor(model => model.Codigo)
</td>

<td>
@Html.TextBoxFor(model => model.Codigo)
</td>

</tr>

<tr>
<td style="width:auto">
@Html.LabelFor(model => model.Descripcion)

</td>

<td style="left: 5px">
@Html.TextBoxFor(model => model.Descripcion, new {@class="myClass", size=50 })

@Html.ValidationMessageFor(model => model.Descripcion)

</td>
</tr>

<tr>

<td>
@Html.LabelFor(model => model.Direccion_1)

</td>

<td>
@Html.TextBoxFor(model => model.Direccion_1, new {@class="myClass", size=50 })

@Html.ValidationMessageFor(model => model.Direccion_1)

</tr>

<tr>

<tr>

@Html.TextBoxFor(model => model.Presidente, new {@class="myClass", size=50 })

<tr>

<tr>
<td class="actionButtons">

<input type="submit" value="Actualizar"/>
</p>
</td>
<td class="actionButtons">
@Html.ActionLink("Regresar a Lista", "Index")
</td>
</tr>

</table>

</fieldset>
}

I don't know how can I send those fields to the controller to call another class that update the data.

I have:

[HTTPPOST}

public ActionResult Editar()

{

but here I don't know how I can referencing the model that I have in the cshtml

}

You Html.BeginForm() should include the controller and action name which will get invoked after form post, something like this.

@Html.BeginForm("Action", "Controller", FormMethod.Post)

and you action method should have the model type as an argument

public ActionResult Editar([ModelType] model)

{

}

Thanks

Make sure your form name which has the above code is Editar.cshtml

[HttpPost]

public ActionResult(Editar editar)
{
  if(ModelState.IsValid)
  {
     db.Editars.Add(editar);
     db.SaveChanges();
     return RedirectToAction("Index");
  }
}

This should work. Please let me know, if there are any issues.

Also, try using, the default Scaffolding feature which will create all the save,update and delete code automatically, where you can learn how these functions are populated.

Thanks everybody to help me on this.

CPrakash82, your example works fine on my code.

Appologize because I'm working on a DB2 database and I can't take advantage from LINQ and SQL server entity framework.

Again, thanks a lot, all of you.
