Meaning of the various symbols in .aspx page of asp.net

It is just syntax.
<% %>
is simply short for <script runat="server"> </script>
aka code render blocks.
<%# %>
are binding expressions (plus the above).
<%= %>
is the above + a Response.Write()
.
<%: %>
is the above + a Response.Write()
wrapped in Html.Encode
(new in .NET 4.0).
<%$ %>
is an ASP.NET expression, used to bind configuration or resource file data during runtime.

Remember it. It's more poorly documented ASP.net syntax to help maintain inconsistencies and fallout from ASP 'classic' groans. Also don't forget
<%=variablename %>

I have come across different symbols in .aspx page of asp.net
<%#eval(expr) %> <%#bind(expr) %> <% %> - for specifying the c# code in aspx page <%$ %> - for specifying the SQL connection string in <asp:SqlDataSource>
Is there any underlying logic behind these symbols or is it just syntax which we have to remember blindly? What does <% %> mean in general?
