Can a Razor view have more than one model without using a ViewModel object?

You should use some prtialviews for other models. You have your main view with main model. Inside of that view, you could have some partialviews with their models and their validations.

--------------------------------------Edit:

As others said it is better to use View Models and combine the models with each others. But as you wanted I created a sample project for you on my Github account:

https://github.com/bahman616/ASPNET_MVC_multiple_models_in_a_view_with_partialview.git

Here is the simplified code of that project:

Here are two models:

public partial class Person
{
    public int ID { get; set; }
    [Required]
    public string Name { get; set; }
}
public partial class Company
{
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
}

I want to have both create views in one view, so this is the parent view:

@model ASP_NET_MVC_Multiple_Models_In_A_View.Models.Person

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.BeginForm("Create","Person")) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Person</legend>

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

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

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

@{Html.RenderAction("_CompanyCreate", "Company");}

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

And this is the partial view:

@model ASP_NET_MVC_Multiple_Models_In_A_View.Models.Company

<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

@using (Html.BeginForm("_CompanyCreate","Company")) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Company</legend>

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

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

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

If you cannot/don't want to modify the model passed to the view then you could pass the additional object in via the ViewBag object. It feels like a hack to me but it works:

Controller:

ViewBag["Model2"] = yourObject

View:

@{var Model2 = ViewBag["Model2"] as yourObjectType;}

Simple answer: No, you can't have two models.

Details There is only one way to declare a Model to be used by a view:

@model [namespace].[path].[ViewModelName]

There is no way to specify multiple of these above.

In addition to that, you can only send one object to a view from the Controller, which would be the model:

public ActionResult WhateverAction()
{
    var model = new MyViewModel();
    return View(model);
}

Theoretically you cant do it because it binds one model to one view. But you can create somethink like a model helper which combines two other models to one

public class model1
{
     string var1 {get; set;}
     string var2 {get; set;}
}

public class model2
{
     string var3 {get; set;}
     string var4 {get; set;}
}

public class modelofBoth
{
     model1 mod1 {get; set;}
     model2 mod2 {get; set;}
}
