Thanks…very useful blog

You should be able to do it in the same way. What problems are you getting?

Glad that it helped

1. e.g view model

public class ProductFormViewModel
{
private CategoryTypeService _svcCategoryType = new CategoryTypeService();
private CategoryService _svcCategory = new CategoryService();

public Product ProductView{ get; set;}
public SelectList CategoryTypes { get; set; }
public SelectList Categories { get; set; }

public ProductFormViewModel()
{
CategoryTypes = new SelectList(_svcCategoryType.GetList(), “ID”, “Name”);
Categories = new SelectList(_svcCategory.GetList(), “ID”, “Name”, null);
}
public ProductFormViewModel(Product Product)
{
ProductView = Product;
CategoryTypes = new SelectList(_svcCategoryType.GetList(), “ID”, “Name”, ProductView.Category.CategoryTypeID);
Categories = new SelectList(_svcCategory.GetList(), “ID”, “Name”, ProductView.CategoryID);
}
}

2.Product Controller “Create” sample

public ActionResult Create(FormCollection formValues)
{

ViewData["ActionFlag"] = ActionType.CREATE;
Product entityToAdd =new Product();
string[] excludePpty = {“Category” };
UpdateModel(entityToAdd ,”ProductView”,null,excludePpty,formValues.ToValueProvider());
entityToAdd.Category = _svcProduct.GetCategoryByProductCategoryID(entityToAdd.CategoryID);
if (ModelState.IsValid)
{
try
{
if (_svcProduct.Create(entityToAdd))
return RedirectToAction(“Index”);
else
return View(“Create”, new ProductFormViewModel(entityToAdd));
}
catch (Exception ex)
{
ModelState.AddModelError(“General”, ex);
return View(“Create”, new ProductFormViewModel(entityToAdd));
}
}
else
{
return View(“Create”, new ProductFormViewModel(entityToAdd));
}
}

Thanks
