Problem appending id to hyperlink in gridview

[Bobby Edward]

What I want is for each row on a gridview to have an "edit" hyperlink.

<asp:HyperLink ID="HyperLink11" runat="server" NavigateUrl='<%#
Bind("ProjectId") %>'>Edit</asp:HyperLink>

Produces the ProjectId fine.

When I try to PRE-PEND it with a page it has problems. For example...

<asp:HyperLink ID="HyperLink11" runat="server"
NavigateUrl='projectdetails.aspx?id=<%# Bind("ProjectId")
%>'>Edit</asp:HyperLink>

Redirects to a url like this...

....projectdetails.aspx?id=%3C%#%20Bind(%22ProjectId%22)%20%%3E

Why???? I want it to do this: projectdetails.aspx?id=5
