I’m trying to make a partial view that acts as the following: When user

  • 0

I’m trying to make a partial view that acts as the following:

  • When user is not logged on, show a registration form.

  • When user is logged on, show me that users information.

I have a partial view that acts as both as registration form, and a user information card; depending on whether or not the user is logged in.

Since this partial view has to be visible from anywhere in the website, I wrote it in the _layout area of the MVC3 application:

<body>
    <div id="wrapper">

        <div id="top">
            <p id="onlinecount">7890 Personas Jugando</p>
            <p id="logoncontrol">ENTRAR | REGISTRARSE</p>
        </div>

        <div id="headercontainer">
            <img src="../../Content/Images/topheadertemp.png" />
        </div>

        <div id="middle">
            <div id="playerinformation">
                @Html.Partial("_RegisterPartial") <!-- HERE! -->
            </div>            

            <div id="centerad">
                <img src="../../Content/Images/premio.png" />
            </div>

            <div id="rightad">
                <img src="../../Content/Images/ganadores.png" />
            </div>

            <div class="clear"></div>
        </div>

        <div id="bottom">@RenderBody()
        </div>

    </div>
</body>

Basically, I need to show a form in that partial if the user is not logged on. However if he IS logged on (via cookie or whatever), I should load a model of his information in order to display the data for his account.

Here’s where I’m stuck. I don’t know how to load the model for this usage. Since this is in the _layout, no controller acts on it if I’m correct, no?

Any suggestions?

    You should look at this previous question, which is similar to yours.

    You should have registration and user information in a single model for your page. (So the answer to your question is that your page only has one model. But your model can be made up of other objects — one for each partial view.)

    So as you see in the link, the user had partial views only use those objects in the page model that pertained to it.

    I think this should help you out. Hope this helps! Good luck.

    UPDATE: Sorry for the delay, but here’s an example (lots of code) that may help:

    Model:
    I create an abstract view model that always has reg and user data in it. Every page’s model could inherit from this abstract.

    public class Registration
{
    public string UserName { get; set; }
    public string Password { get; set; }
}

public class UserData
{
    public string DisplayName { get; set; }
    public int Age { get; set; }
}

public abstract class RegModelViewModelBase
{
    public string Title { get; set; }
    public Registration RegInfo { get; set; }
    public UserData UserInfo { get; set; }
}

public class MainPageViewModel : RegModelViewModelBase
{
}

    Controller:
    Here, I just instantiate the concrete view model for this page/view (MainPageViewModel). I set properties (which could come from the database, etc.). I pass the view model to the view.

    public class HomeController : Controller
{
    public ActionResult Index()
    {
        MainPageViewModel hpvm = new MainPageViewModel();

        hpvm.Title = "Some Cool Page";
        hpvm.RegInfo = new Registration() { Password = "blah", UserName = "dhoerster" };
        hpvm.UserInfo = new UserData() { DisplayName = "David Hoerster", Age = 125 };

        return View(hpvm);
    }
}

    View — _Layout.cshtml:
    Notice that the first line in my model sets the model object for my _layout template. I’m getting this view model from the controller, and I can reference it in _layout (or other template). I don’t do much here, except get a partial view (_RegStuff) and pass to it my RegInfo from my model (which was set in the controller):

    @model MvcApplication1.Models.RegModelViewModelBase

<!DOCTYPE html>
<html>
<head>
    <title>@Model.Title</title>
</head>

<body>
    @Html.Partial("_RegStuff", Model.RegInfo)
    @RenderBody()
</body>
</html>

    View — _RegInfo.cshtml:
    Dirt simple, but again I set my model type that this partial view expects to be passed in.

    @model MvcApplication1.Models.Registration
<div>User Name = @Model.UserName</div>

    View — Index.cshtml:
    Again, set the model and use it in my index view.

    @model MvcApplication1.Models.MainPageViewModel

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>@Model.Title</h2>
<h3>Display Name = @Model.UserInfo.DisplayName</h3>

    So throughout, I can reference the model set in my controller.

    I hope this explains what I was trying to get at. If not, I can update this accordingly.

    Thanks!
