Question

EDIT

I put my solution on a share site. Like that you’ll be able to see what I’m talking about. You can download it here : http://www.easy-share.com/1909069597/TestRenderAction.zip

To test it, start the project (let the create form empty) and click the Create button. You’ll see what happen.

It’s only a example project. I don’t care to persist my object to the database for now. I care to make my example work.

I got the following controller :

public class ProductController : Controller
{
    public ActionResult List()
    {
        IList<Product> products = new List<Product>();

        products.Add(new Product() { Id = 1, Name = "A", Price = 22.3 });
        products.Add(new Product() { Id = 2, Name = "B", Price = 11.4 });
        products.Add(new Product() { Id = 3, Name = "C", Price = 26.5 });
        products.Add(new Product() { Id = 4, Name = "D", Price = 45.0 });
        products.Add(new Product() { Id = 5, Name = "E", Price = 87.79 });

        return View(products);
    }

    public ViewResult Create()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Create(Product product)
    {
        return View(product);
    }
}

The following model :

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public double Price { get; set; }
}

My Product/List.aspx :

<h2>List</h2>

<table>
    <tr>
        <th></th>
        <th>
            Id
        </th>
        <th>
            Name
        </th>
        <th>
            Price
        </th>
    </tr>

<% foreach (var item in Model) { %>

    <tr>
        <td>
            <%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> |
            <%= Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ })%>
        </td>
        <td>
            <%= Html.Encode(item.Id) %>
        </td>
        <td>
            <%= Html.Encode(item.Name) %>
        </td>
        <td>
            <%= Html.Encode(String.Format("{0:F}", item.Price)) %>
        </td>
    </tr>

<% } %>

</table>

<p>
   <% Html.RenderAction("Create"); %>
</p>

My Product/Create.ascx :

<%= Html.ValidationSummary("Create was unsuccessful. Please correct the errors and try again.") %>

<% using (Html.BeginForm("Create", "Product", FormMethod.Post)) {%>

    <fieldset>
        <legend>Fields</legend>
        <p>
            <label for="Id">Id:</label>
            <%= Html.TextBox("Id") %>
            <%= Html.ValidationMessage("Id", "*") %>
        </p>
        <p>
            <label for="Name">Name:</label>
            <%= Html.TextBox("Name") %>
            <%= Html.ValidationMessage("Name", "*") %>
        </p>
        <p>
            <label for="Price">Price:</label>
            <%= Html.TextBox("Price") %>
            <%= Html.ValidationMessage("Price", "*") %>
        </p>
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>

<% } %>

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

The problem is that when I hit the create button and I got an error (like empty field), the return view only return my Create.ascx control. It’s doesn’t return the Product/List.asxp page with in my Create.ascx control with the errors. That’s what I would like it’s does.

Any idea how I can solve that problem ?

I use Asp.Net Mvc 1 with Asp.Net Futures (which have the Html.RenderAction).

Answer 1

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Product product)
{
  ...
  return View("List");
}

or

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Product product)
{
  ...
   return RedirectToAction("List", "Product");
}
