databinding to a hyperlink control.

[Wokawidget]

I have:

<asp:HyperLink id="lnkEdit" ImageUrl="/Resource/Edit.gif" NavigateUrl='<%# DataBinder.Eval(container.DataItem, "DivisionKey") %>' runat="server">
</asp:HyperLink>

Which is good.
When I hover my mouse over it show's this correctly.
However, for the navigate URL I would like:

NavigateUrl='Woof.aspx?Moose=<%# DataBinder.Eval(container.DataItem, "DivisionKey") %>'

BUT when I add the Woof.aspx text then the hyperlink no longer displays the value from my dataset, but in fact actually shows the "<%# DataBinder..." in my link.

Any ideas?
