Cant change quantity in cart once discount is applied

[richa]

AbleCommerce version? 7.0.5 build 14053
In the Shopping cart, you can change the quantity of any item, until a discount is applied. Once a discount is applied, you can change the quantity of only the first item in the cart.

Do you have custom code on the basket? I'm not seeing that problem in a 7.0.5 site.

we call a method: ShowDiscountMessageInfo(); in page load in basket.ascx.cs

Code: Select all

private void ShowDiscountMessageInfo()
    {
        VolumeDiscountCollection volumeDiscountCollection = VolumeDiscountDataSource.LoadForStore();
        for (int i = 0; i < volumeDiscountCollection.Count; i++)
        {
            VolumeDiscount volumeDiscount = volumeDiscountCollection[i];

            if (string.Compare(volumeDiscount.Name, "new discount", StringComparison.OrdinalIgnoreCase) == 0)
            {
                VolumeDiscountLevelCollection volumeDiscountLevelCollection = volumeDiscountCollection[i].Levels;
                BasketHelper.SaveBasket(BasketGrid);
                BindBasketGrid();

                LSDecimal subTotalOfCart = GetBasketSubtotalWithoutDiscount();

                bool discountApplied = false;
                for (int j = 0; j < volumeDiscountLevelCollection.Count; j++)
                {
                    VolumeDiscountLevel volumeDiscountLevel = volumeDiscountLevelCollection[j];
                    if (volumeDiscountLevel.MinValue - subTotalOfCart < 10 &&
                        volumeDiscountLevel.MinValue - subTotalOfCart > 0)
                    {
                        bool isPercent = volumeDiscountLevel.IsPercent;
                        string discountAmount = string.Empty;
                        if (isPercent)
                        {
                            discountAmount = (volumeDiscountLevel.DiscountAmount / 100).ToString("0.00%");
                        }
                        else
                        {
                            discountAmount = volumeDiscountLevel.DiscountAmount.ToString("C");
                        }
                        lblDiscountInfo.Text = (volumeDiscountLevel.MinValue - subTotalOfCart).ToString("C") +
                                               " more and you will save " + discountAmount + " on your entire order";
                        discountApplied = true;
                        break;
                    }
                }
                if (!discountApplied)
                {
                    divDiscountInfo.Visible = false;
                }
                else
                {
                    divDiscountInfo.Visible = true;
                }
            }
        }
    }

i put this additional code in a clean install and it works fine. but just doesnt work on the real website....

There has to be some other difference on the live site. Try checking for nulls in your code and see if that helps.
