[thelist] no forms from with user controls?

[Ken Schaefer]

Can I strongly suggest you go and buy the ASP.NET Unleashed book
mentioned earlier? Everything will be much, much clearer then.

With .NET v1/v1.1 you can, OOB, only have a single server-side form,
one that has:

<form runat="server"></form>

(ie a form that ASP.NET on the server-side is aware of). Since a user
control is designed to be re-used, you should not include a
server-side form tag inside the user control, since the user control
may, potentially, be placed on a page that already have a server-side
<form> tag in it.

To answer your question - you do not need a <form> tag to
implement/use a user-control per se. However, some things (such as
some server-side form web controls) need to be inside a <form> (just
like some HTML elements such as <input> need to be inside a <form>),
and if you use those inside your user control, then they need to be
inside a form at some point.

Note: you can have as many <form> tags as you like on a page - you can
only have a single server-side <form runat="server"> on a page.

OK, on the "Classic ASP" issue - who did this?

<% If foo then %>
<!-- #include -->
<% Else %>
<!-- #include -->
<%End if%>

ugh! That's yucky code :-)

To replicate this in ASP.NET, in the simplest form, you could have two
literal or panel controls, and you could do something like:

<script runat="server">
If foo then
   Panel1.Visible = True
Else
   Panel2.Visible = True
End If
</script>

Cheers
Ken
