<% versus <%#

[Derek Fountain]

Just working through some beginners tutorials over at asp.net, I came
across the use of the <%# construct to embed code snippets. Eg:

<asp:HyperLink ID="HyperLink2" runat="server"
NavigateUrl='<%# Eval("Url") %>'>
<%# Eval("Title") %>
</asp:HyperLink>

All the documentation I can find says code is embedded with <% %> tags.
I can't find any mention of the the additional # symbol anywhere. Yet if
I remove it, the examples stop working.

Can someone point me at the thing I'm supposed to read that makes sense
of this?

<% %> are the delimeters that indicate server side code. The # symbol is
used to represent a databind or eval operation.

Do you have a link to something I can read on this? It's all very new
to me, and I didn't even know such special symbols existed...
