Dynamically set a hyperlink control's NavigateUrl property inline

How can I dynamically set a stand alone(not in gridview) hyperlink control's NavigateUrl property inline in the aspx page?

I have tried to do the following, but it did not work.

<asp:HyperLink id="MyLink"
  NavigateUrl="../mypage.aspx?id=<%= pageid %>"
  runat="server">My Page</asp:HyperLink>
