给DropDownList添加ToolTip（title）属性

实现过程，只是为DropDownList控件写OnDataBound事务

protected void ddlCompany_DataBound(object sender, EventArgs e)
        {
            DropDownList ddl = (DropDownList)sender;
            for (int i = 0; i < ddl.Items.Count; i++)
            {
                ddl.Items[i].Attributes.Add("title", ddl.Items[i].Text);
            }

        }
