// Totally generic sorting for use with a gridview

public List Sort_List(string sortDirection, string sortExpression, List data)
    {

        List data_sorted = new List();

        if (sortDirection == "Ascending")
        {
            data_sorted = (from n in data
                              orderby GetDynamicSortProperty(n, sortExpression) ascending
                              select n).ToList();
        }
        else if (sortDirection == "Descending")
        {
            data_sorted = (from n in data
                              orderby GetDynamicSortProperty(n, sortExpression) descending
                              select n).ToList();

        }

        return data_sorted;

    }

    public object GetDynamicSortProperty(object item, string propName)
    {
        //Use reflection to get order type
        return item.GetType().GetProperty(propName).GetValue(item, null);
    }
