Question

Can anyone help with transferring form from one view to another in MVC3/C#?

Here is the scenario:

1) I have create page where i have about 6 field for user to enter once user submit that field it will redirect them to review page.

2) Once user come on the review page, the information he entered in the create page should appear there (for user to confirm).

3) There will be a edit button on the review page so if the user clicks on the edit button then he should go back to the create page where he had entered all information, so he can update them again.

Can we handle this scenario using ViewData/ViewBag or partial view? I don’t know how to do that.

Answer 1

You should create a class in your Models folder, let’s call it MyViewModel, and you’ll define in that class all the 6 property you need the user to edit.
In the create view, you’ll present all your input field inside a form element defined to postback to your review action. The significant part of your view, will be:

@model MyViewModel
@using (Html.BeginForm("Review", "MyController"))
{
   //here there's your input field
   @Html.TextBoxFor(m => m.prop1)
   // and so on
}

In MyController class, you’ll have the Review method defined as following

public ActionResult Review(MyModel mm) 
{
    if (ModelState.IsValid)
    {
        return View(mm);
    } else return RedirectToAction("Create");
}

And at last, in your Review view, you’ll have:

 @model MyViewModel
 //show up all the field to be reviewed
 @Html.DisplayFor(m=>m.prop1)
 //and so on
 // now a form to pastback again all the data to the edit page
 @using (Html.BeginForm("Edit", "MyController"))
 {
   //here there's your hidden field
   @Html.HiddenFor(m => m.prop1)
   // and so on
   <input type="submit" value="Re-edit the fields"/>
 }

Your controller class MyController will have the following code:

public class ViaggioController : Controller
{
public ActionResult Create() 
{
    var emptyModel = new MyViewModel();
    return RedirectToAction("Edit", new { mm = emptyModel });
}
public ActionResult Edit(MyViewModel mm) 
{    
    return View(mm);
}

public ActionResult Review(MyViewModel mm) 
{
    if (ModelState.IsValid)
    {
        return View(mm);
    } 
    else 
        return RedirectToAction("Create");
}
}
