The cart doesn't seem to be saving order notes for aspdotnetstorefront admin Sp1. code was missing from the shoppingcart.aspx.cs file. So in order for you to fix this bug,
Just insert the following
if (!AppLogic.AppConfigBool("DisallowOrderNotes"))
{
if (OrderNotes.Text.Trim().Length > 0)
{
SqlParameter sp = new SqlParameter("@OrderNotes", SqlDbType.NText);
sp.Value = OrderNotes.Text.Trim();
SqlParameter[] spa = { sp };
ThisCustomer.UpdateCustomer(spa);
}
}
Under the following
UpdateCartQuantity();
// save coupon code, no need to reload cart object
// will update customer record also:
if (cte == CartTypeEnum.ShoppingCart)
{
cart.SetCoupon(CouponCode.Text, true);
