How to have more than one Model on a form

Jan 18, 2013 01:09 PM|LINK

Hi All,

I have a form which is split in 7 difference ways, Personal information, Employer, Previous Employment etc basically its an application form.

Each section within the form has its model so

Personal Information Section points at -> CandidateDetails

Employer points at -> CandidateEmployment

etc

Now my question is this how can i wrap all these models in to one for example MasterModel and use it on the form, allowing me to access other models within the MasterModel etc?

Thanks

Exactly how you said it. Create a MasterModel class and all others will be properties with get/set on MasterModel.

make a viewmodel containing the models you need in the view

public class myViewModel
{
 public Car car {get;set;}
 public Truck truck {get;set;}
 ......

}

Challenge the best, die like the rest.

Hi thanks for the information,

Correct me if im being stupid, ViewModel is it just another Model which inherits all other models? then you just create the one view for the model and bosh there you have it?

No, it does not inherit. It aggregates the other models.

A good tutorial as far as a View Model is concerned at this web page

Hi Sorry to post on a post which has been going for a few days/weeks since any one touched it!

but im having a problem referencing controls located in other models etc

i keep getting "Object reference not set to an instance of an object."

This is my view where im using all my models.

<div class="blue-border-form-details">
        <h1>Personal Information</h1>
        <fieldset>
        <legend><label>* Title:</label><%= Html.DropDownList("CandidateTitle", Model.CandidateDetails.TitleCollection())%></legend>
        <legend><label>* First name:</label><%= Html.TextBox("CandidateFirstName", Model.CandidateDetails.CandidateFirstName, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Surname:</label><%= Html.TextBox("CandidateSurname", Model.CandidateDetails.CandidateSurname, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Known As:</label><%= Html.TextBox("CandidateKnownAs", Model.CandidateDetails.CandidateKnowAs, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Home Number:</label><%= Html.TextBox("CandidateHomeNum", Model.CandidateDetails.CandidateHomeNum, new { maxlength = 11, size = "30", @class = "number", autocomplete = "off" })%></legend>
        <legend><label>* Mobile Number:</label><%= Html.TextBox("CandidateMobileNum", Model.CandidateDetails.CandidateMobileNum, new { maxlength = 11, size = "30", @class = "number", autocomplete = "off" })%></legend>
        <legend><label>* Email:</label><%= Html.TextBox("CandidateEmail", Model.CandidateDetails.CandidateSurname, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Driving License:</label><%= Html.RadioButton("DrivingLicense", Model.CandidateDetails.DrivingLicense, true)%>Yes</legend><legend>
                <label>&nbsp;</label><%= Html.RadioButton("DrivingLicense", Model.CandidateDetails.DrivingLicense, false)%>No</legend>
        <legend><label>* Address</label><%= Html.TextBox("Address1", Model.CandidateAddress.Address1, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Address2</label><%= Html.TextBox("Address2", Model.CandidateAddress.Address2, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Address3</label><%= Html.TextBox("Address3", Model.CandidateAddress.Address3, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>&nbsp; Address4</label><%= Html.TextBox("Address4", Model.CandidateAddress.Address4, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Postcode</label><%= Html.TextBox("PostCode", Model.CandidateAddress.PostCode, new { maxlength = 7, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Town</label><%= Html.TextBox("Town", Model.CandidateAddress.Town, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* County</label><%= Html.TextBox("County", Model.CandidateAddress.County, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        <legend><label>* Driving License:</label><%= Html.RadioButton("WorkedForBPDBefore", Model.CandidateApplication.WorkedForBPDBefore, true)%>You have worked for BPD before</legend>
        <legend><label>&nbsp;</label><%= Html.RadioButton("WorkedForBPDBefore", Model.CandidateApplication.WorkedForBPDBefore, false)%>Haven`t worked for BPD Before</legend>
        <legend><label>* If "Yes" When and What position did you apply for?</label><%= Html.TextBox("WhenWorkedForBPDBefore", Model.CandidateApplication.WhenWorkedForBPDBefore, new { maxlength = 50, size = "30", autocomplete = "off" })%></legend>
        </fieldset>
</div>

At the top of the page i have this

<%@ Page Title="BPD.Jobs Application Form" Language="C#" MasterPageFile="~/Views/Shared/main.master" Inherits="System.Web.Mvc.ViewPage<BpdJobsModal.CandidateApplicationForm>" %>

this is my ViewModel

namespace BpdJobsModal
{
    public class CandidateApplicationForm // CandidateApplicationForm is the main Model on the View - ApplicationForm within BPD.Jobs
    {
       #region "Properties"

       public CandidateAddress CandidateAddress { get; set; } // Candidate Address Details
       public CandidateCheckEmail CandidateCheckEmail { get; set; } // Candidates Email address checked against the DB
       public CandidateApplication CandidateApplication { get; set; } // Candidates Application Details
       public CandidateDetails CandidateDetails { get; set; } // Candidates Details firstname, surname etc
       public CandidateEducation CandidateEducation { get; set; } // Candidates Education
       public CandidateEmployment CandidateEmployment { get; set; } // Candidates Current employment
       public CandidateEmploymentGaps CandidateEmploymentGaps { get; set; } // Candidates Employment gaps
       public CandidatePreviousEmployment CandidatePreviousEmployment { get; set; } // Candidates Previous Employments history
       public CandidateVoluntaryWork CandidateVoluntaryWork { get; set; } // Candidates Voluntary work, if any.

       #endregion
    }
}

and this is my controller which returns the model "CandidateApplicationForm"

First im checking the email address which is passed in is valid if it is then return the view with the Model

  public ActionResult application(string EmailAddress)
        {
            if(string.IsNullOrWhiteSpace(EmailAddress))
            {
                ViewData["Message"] = "Email Address Invalid";
                return View();
            }
            else
            {
                CandidateCheckEmail objCheckEmail = new CandidateCheckEmail();
                CandidateCheckEmailManager objCheckEmailManager = new CandidateCheckEmailManager();
                objCheckEmail.RecordExist = objCheckEmailManager.Load(EmailAddress);
                                
                if (objCheckEmail.RecordExist > 0)
                {
                    CandidateApplicationForm objCandidateApplicationForm = new CandidateApplicationForm();
                    return View(objCandidateApplicationForm);
                }
                else
                {
                    ViewData["Message"] = "Your email address doesnt exist in our Database.";
                    return View();
                }
            }
        }

Any help would be highly appreciated.
