Add additional information

Following code demonstrates how to add addtiional payment info.

using System;
using Litium.Foundation.Modules.ECommerce;
using Litium.Foundation.Modules.ECommerce.Carriers;
using Litium.Foundation.Security;
using Litium.Foundation.Modules.CMS;
using Litium.Foundation.Modules.CMS.GUI.Templates;

public partial class Site_Samples_Checkout_CheckoutAddAdditionalInfo : BaseTemplate
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }

    void AddAdditionalInfo()
    {
        var currentOrderCarrier = CurrentState.Current.ShoppingCart.OrderCarrier;
        //add some sample additional payment info to all payments.
        currentOrderCarrier.PaymentInfo.ForEach
            (x => CreateOrUpdateAdditionalPaymentInfo(x, "SampleAdditionalInfo", "SampleValue", CurrentState.Current.Token));
    }

    /// <summary>
    /// Creates or updates additional payment info.
    /// </summary>
    /// <param name="paymentInfoCarrier"></param>
    /// <param name="key"></param>
    /// <param name="value"></param>
    /// <param name="token"></param>
    public void CreateOrUpdateAdditionalPaymentInfo(PaymentInfoCarrier paymentInfoCarrier, string key, string value, SecurityToken token)
    {
            AdditionalPaymentInfoCarrier additionalInfo = paymentInfoCarrier.AdditionalPaymentInfo.Find(x => x.Key == key);
            if (additionalInfo == null)
            {
                additionalInfo = new AdditionalPaymentInfoCarrier(key, paymentInfoCarrier.ID,value);
                paymentInfoCarrier.AdditionalPaymentInfo.Add(additionalInfo);
            }
            else
                additionalInfo.Value = value;
    }
}

Adding the additional order info and addtional delivery info follows the same pattern as above.
