You might want to try changijng your method's parameter list:

C#

private void AttachTooltipForDropdowns(ref DropDownList ddlTarget)
{
    for (int i = 0; i < ddlTarget.Items.Count; i++)    
    {
        ddlTarget.Items[i].Attributes.Add("title", ddlTarget.Items[i].Text);    
    }
}

protected void Page_Prerender(object sender, EventArgs e)
{
    AttachTooltipForDropdowns(ref ddlf1);
    AttachTooltipForDropdowns(ref ddlf2);
}

Just a guess/question that comes to my mind: By any chance are you looking this in IE6?
If so, you may not be able to see the ToolTip text of dropdownlist items in IE 6.0. i
It works with higher version of IE.

Try to call the method "AttachTooltipForDropdowns" in pre_render event of dropdownlist. It worked for me.

C#

protected void Page_InitComplete(object sender, EventArgs e)
{
drp.PreRender += new EventHandler(DropDown_PreRender);
}

 public void DropDown_PreRender(object sender, EventArgs e)
        {
            DropDownList ddl = sender as DropDownList;
            if (ddl != null)
            {
                foreach (ListItem li in ddl.Items)
                {
                    // setting text value of item as tooltip
                    li.Attributes.Add("title", li.Text);
                }
            }
        }
  {
