How do I dynamically add _blank to hyperlink control?

Presently in my mark up I have a hyperlink control written as so (see the code). I'd like for it to open in a new window, based on whether or not there is a document associated with a particular record (see function, also in code section) or not. How do I accomplish this?
------------MARKUP---------

                        <asp:HyperLink runat="server" NavigateUrl='<%# GetDocOrPage(Container.DataItem as DigitalLagoon.BL.NewsRelease) %>'> "_blank" would go here if i wanted it to do it all the time.
                            <asp:Literal ID="lblArticleText" runat="server" Text='<%# GetArticlePreview(Eval("HeadlineText")) %>' />
                        </asp:HyperLink>

---------C# FUNCTION-------------

    protected string GetDocOrPage(NewsRelease newsRelease)
    {

        if (newsRelease != null)
        {
            if (newsRelease.HasLinkToDocument)
            {
                if (!String.IsNullOrEmpty(newsRelease.DocumentLink))
                {
                    string path = Path.Combine(SiteSettings.DocumentsVirtualPath, newsRelease.DocumentLink).Replace("\\", "/"); <--i believe this line is where i'll need to add the "_blank"
                    if (File.Exists(Server.MapPath(path)))
                        return path;
                }

            }

            if (newsRelease.NewsReleaseUid > 0)
                return "/displayNewsRelease.aspx?NewsReleaseUid=" + newsRelease.NewsReleaseUid;
        }
        return "newsReleases.aspx";

    }

Since you're doing data binding, you'll have to do it in one of the data-binding events for the containing control. Which data control is the above markup contained by?

@kaufmed: see code below
<asp:Repeater ID="rptNewsReleases" runat="server" DataSourceID="dsNewsReleaseList"
            OnItemDataBound="rptNewsReleases_ItemDataBound">
            <HeaderTemplate>
                <ol class="dl-news-list">
            </HeaderTemplate>
            <ItemTemplate>
                <li>
                    <p class="dl-news-release-dt">
                        <asp:Literal runat="server" Text='<%# Eval("ReleaseDate","{0:MM.yyyy}") %>' />
                        &nbsp
                        <asp:HyperLink runat="server" NavigateUrl='<%# GetDocOrPage(Container.DataItem as DigitalLagoon.BL.NewsRelease) %>' Target="_blank">
                            <asp:Literal ID="lblArticleText" runat="server" Text='<%# GetArticlePreview(Eval("HeadlineText")) %>' />
                        </asp:HyperLink>
                        <asp:HyperLink runat="server" NavigateUrl='<%# String.Format("/displayNewsRelease.aspx?NewsReleaseUid={0}", Eval("NewsReleaseUid")) %>'
                            Text="More" /></p>
                </li>
            </ItemTemplate>
            <FooterTemplate>
                </ol>
            </FooterTemplate>
        </asp:Repeater>

Try this; you already have the ItemDataBound handler declared. Within that handler, try something like the following. I have used 0 as the indexer, but try adjusting your indexes according to the position of each "runat=server" tagged tag (server tags basically). For instance, I would say the Literal control is index 0, the first Hyperlink is 1, and the second HyperLink is 2.
protected void rptNewsReleases_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    (e.Item.Controls[0] as HyperLink).Target = "_blank";
}

figured it out. added a function to the Target property of the hyperlink control. i passed the current data item and based on a value of one of its members i either returned "_blank" or "" (also blank ;-) ). and that did the trick. thanks for your time and help.
