get the total nb of products (including quantities)

[ZaR]

Hello,

Is there a quick way to get the count of products including
quantities ?

Example :
in cart : 2 products A + 1 products B -> get the count=3 (and not 2 as
in "You have <%#Container.Count%> products." in
<manyitemscartitemtemplate>.)

Thanks

Hi,

 

You can for example add this method in class cartprovider:

 

  public int DistinctProductCount
  {
   get
   {
    if (List != null)
    {
     return List.Select(i => i.ProductId).Distinct().Count();
    }
    return 0;
   }
  }

 

I have just add it in the code that you can find on GoogleCode

Thanks.
I see no update on Google Code.
So I'm trying to update the CartProvider class, but I get the
following build error :

Erreur 2
'System.Collections.Generic.List<ShoppingCart.CartItem>' ne
contient pas une définition pour 'Select' et aucune méthode
d'extension 'Select' acceptant un premier argument de type
'System.Collections.Generic.List<ShoppingCart.CartItem>' n'a été
trouvée (une directive using ou une référence d'assembly est-elle
manquante ?)


(for english readers : no definition for 'Select' method, using /
assembly reference may be missing)


I've tried to add System.Data.Linq.
No change.
Any idea?


;)

I did not yet Commited the code, it is good now.

 

The using for use the method "Select" is System.Linq

To get the thing done, here is my code :

---
CartProvider:

public int DistinctProductCount
{
get
{
if (List != null)
{

int intDistinctProductCount = 0;
foreach (var i in List)
{
intDistinctProductCount += i.Quantity;
}
return intDistinctProductCount;
}
return 0;
}
}

---
Cart:
public static int DistinctProductCount
{
get
{
return Provider.DistinctProductCount;
}
}

---
CartInformations:
[Bindable(true)]
[Category("Information")]
[Description("How many distinct items in cart")]
public int DistinctProductCount
{
get { return Cart.DistinctProductCount; }
}

---
Usage in <CART:Informations>:
<OneItemCartItemTemplate>...<%#Container.DistinctProductCount%> product
(s)...</oneitemcartitemtemplate>
<ManyItemsCartItemTemplate>...<%#Container.DistinctProductCount%>
products...</manyitemscartitemtemplate>
