MVC strongly typed view data - asp.net-mvc

Question

I have a strongly typed view that creates the form fields like this:
#Html.TextBoxFor(x => x.Name, new { #class = "form-control" })
That's fine, X in the above lambda expression relates to a class I've created with a property of 'Name'.
How do I use this same view but have access to the properties of a different class? For example if you imagine I've another class called - UserDetails, and email address is a property of that. How can I do this:
#Html.TextBoxFor(x => x.Email, new { #class = "form-control" })
within the same strongly typed view?

Answer 1

In asp.net mvc you pass model to view like this:
public ActionResult Base()
{
return View(new DerviedOne());
}
And here is your models definitions :
public class BaseModel
{
public int Id { get; set; }
}
public class DerviedOne : BaseModel
{
public string Email { get; set; }
}
public class DerviedTwo : BaseModel
{
public string Name { get; set; }
}
Then you have to create three views:
Base View:
#using Models
#model Models.BaseModel
#{
ViewBag.Title = "Base";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Base</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>BaseModel</h4>
<hr/>
#Html.ValidationSummary(true, "", new {#class = "text-danger"})
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
#Html.TextBoxFor(x=>x.Id)
<input type="submit" value="Create" class="btn btn-default"/>
</div>
</div>
</div>
if(Model is DerviedOne)
{
Html.RenderPartial("DerviedOneView", Model as DerviedOne);
}
if (Model is DerviedTwo)
{
Html.RenderPartial("DerviedTwoView", Model as DerviedTwo);
}
}
Second view:
#model WebApplication.Models.DerviedOne
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>DerviedOne</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Email, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Email, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Email, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
Third view:
#model WebApplication.Models.DerviedTwo
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>DerviedTwo</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Name, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Name, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
