good use of my unit of work?

Hi,

I have the following page load method:
 

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            using (var db = new PublicUnitOfWork())
            {                
                DisplayPageCMS(litPageTitle, litMetaKeywords, litMetaDescription, litBodyText, db);
            }
        }
    }

Select allOpen in new window

It calls the following method in my base class:

public void DisplayPageCMS(Literal litPageTitle,Literal litMetaKeywords ,Literal litMetaDescription,Literal litBodyText, PublicUnitOfWork db)
    {
        Page p = db.Pages.FindById(1);

        //do some work to set the lit values of my meta tags etc
    }

Select allOpen in new window

I'm just wondering is the best way to use my PublicUnitOfWork or should the base class function be creating its own.

Note in my page load I may want to use the publicunitofwork some more for other things...

I'd appreciate some input/feedback on this.

Thanks
