multi-step registration process issues in asp.net mvc (split viewmodels, single model)

Question

I have a multi-step registration process, backed by a single object in domain layer, which have validation rules defined on properties.

Answer 1

Adding more info from @Darin's answer.

What if you have separate design style for each steps and wanted maintain each in separate partial view or what if you have multiple properties for each step ?

While using Html.EditorFor we have limitation to use partial view.

Create 3 Partial Views under Shared folder named : Step1ViewModel.cshtml , Step3ViewModel.cshtml , Step3ViewModel.cshtml

For brevity I just posting 1st patial view, other steps are same as Darin's answer.

Step1ViewModel.cs

[Serializable]
public class Step1ViewModel : IStepViewModel
{
  [Required]
  public string FirstName { get; set; }

  public string LastName { get; set; }

  public string PhoneNo { get; set; }

  public string EmailId { get; set; }

  public int Age { get; set; }

 }

Step1ViewModel.cshtml

 @model WizardPages.ViewModels.Step1ViewModel


    
Personal Details

    

        First Name:
        

            @Html.TextBoxFor(x => x.FirstName)
        
    
    

        Last Name:
        

            @Html.TextBoxFor(x => x.LastName)
        
    
    

        Phone No:
        
 
            @Html.TextBoxFor(x => x.PhoneNo)
        
    
    

        Email Id:
        

            @Html.TextBoxFor(x => x.EmailId)
        
    

Index.cshtml

@using Microsoft.Web.Mvc
@model WizardPages.ViewModels.WizardViewModel

@{
    var currentStep = Model.Steps[Model.CurrentStepIndex];

    string viewName = currentStep.ToString().Substring(currentStep.ToString().LastIndexOf('.') + 1);
}

Step @(Model.CurrentStepIndex + 1) out of @Model.Steps.Count

@using (Html.BeginForm())
{
    @Html.Serialize("wizard", Model)

    @Html.Hidden("StepType", Model.Steps[Model.CurrentStepIndex].GetType())

    @Html.Partial(""+ viewName + "", currentStep);

    if (Model.CurrentStepIndex > 0)
    {

     

    }

    if (Model.CurrentStepIndex < Model.Steps.Count - 1)
    {

      

    }
    else
    {

      

    }
}
