Fill a dropdownlist with a range of numbers in single line

We all have to create dropdownlists which contains a range of values, may be days in a month 1 to 31 or may be years like 2013 to and what we always do ? will write a for loop everywhere we need this. I am presenting you an extension method for dropdownlist to simplify this. If we have this control extension in our application, you just need a single line to bind a range of integer values to a drop down list. Lets see the code now

    /// 

    /// Fills a dropdownlist with numbers according to range specified
    /// 

    /// Dropdownlist to be filled
    /// starrting value
    ///  ending value
    /// incrementing value
    /// do we need to add a default "select" item
    /// if you do not need "select" specify default text
 public static void FillNumbers(this DropDownList ddl, int start, int end, int seed, bool includeSelect, string defaultText)
    {
        ddl.Items.Clear();

        if (start > end)
        {
            for (int i = start; i >= end; i = i - seed)
            {
                ddl.Items.Add(i.ToString());
            }
        }
        else
        {
            for (int i = start; i <= end; i = i + seed)
            {
                ddl.Items.Add(i.ToString());
            }
        }

        if (includeSelect)
        {
            string selecttext = "-Select-";
            if (!string.IsNullOrEmpty(defaultText))
                selecttext = defaultText;
            ddl.Items.Insert(0, new ListItem(selecttext, "0"));
        }
    }

public static void FillNumbers(this DropDownList ddl, int start, int end, int seed, bool includeSelect)
    {
        FillNumbers(ddl, start, end, seed, includeSelect, "");
    }
    public static void FillNumbers(this DropDownList ddl, int start, int end, int seed)
    {
        FillNumbers(ddl, start, end, seed, false, "");
    }
    public static void FillNumbers(this DropDownList ddl, int start, int end)
    {
        FillNumbers(ddl, start, end, 1, false, "");
    }
