DropDownlist value returns 0

Hi, I've got a DropDown list which is populated here.

with the use of a break in the code there is a value of 4 for shippingInfo.ShippingID.ToString()
ASP.NET Syntax (Toggle Plain Text)

Code:

---

if (addressOK) //&& cardOK
        {
            int shippingRegionId = int.Parse(Profile.ShippingRegion);
            List<ShippingInfo> shippingInfoData =
                CommerceLibAccess.GetShippingInfo(shippingRegionId);
            foreach (ShippingInfo shippingInfo in shippingInfoData)
            {
                shippingSelection.Items.Add(
                    new ListItem(shippingInfo.ShippingType,
                        shippingInfo.ShippingID.ToString()));
            }
            shippingSelection.SelectedIndex = 0;
        }

---

if (addressOK) //&& cardOK { int shippingRegionId = int.Parse(Profile.ShippingRegion); List<ShippingInfo> shippingInfoData = CommerceLibAccess.GetShippingInfo(shippingRegionId); foreach (ShippingInfo shippingInfo in shippingInfoData) { shippingSelection.Items.Add( new ListItem(shippingInfo.ShippingType, shippingInfo.ShippingID.ToString())); } shippingSelection.SelectedIndex = 0; }

then when the checkout button is selected here:

Code:

---

protected void placeOrderButton_Click(object sender, EventArgs e)
    {
            // store the total amount
        decimal amount = ShoppingCartAccess.GetTotalAmount();
            // get shippingId or default to 0
        int shippingId = 0;
        int.TryParse(shippingSelection.SelectedValue, out shippingId);
            // get tax ID or defalut to "No Tax"
        string shippingRegion =
            (HttpContext.Current.Profile as ProfileCommon).ShippingRegion;
        int taxId;
        switch (shippingRegion)
        {
            case "2":
                taxId = 1;
                break;
            default:
                taxId = 2;
                break;
        }
            // create the order and store the order id
        string orderId =
            ShoppingCartAccess.CreateCommerceLibOrder(shippingId, taxId);
            // process order
        OrderProcessor processor = new OrderProcessor(orderId);
        processor.Process();   
            // redirect to confirmation page
        Response.Redirect("OrderPlaced.aspx");
    }

with the use of a breakpoint the shippingId is 0 although a selection is made. Therefore I get an error

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Orders_Shipping". The conflict occurred in database "firebyte", table "dbo.Shipping", column 'ShippingID'.

Could it be you rebind the drop down (or reassign) on post back?

Hi I solved the problem, somehow in this line of code where the DropDown is populated it was setting it to 0:

shippingSelection.SelectedIndex = 0;

I removed that and had to put where the DropDown is populated in its own method.

hay,
if you are populating your dropdownlist in the page load with out checking the IsPostBack
then it will lose its selection while you postback

please don't forget to remark the thread as resolved
