Hi Aussie,
The ASP.NET web page is a customized html based web page, one particularity
is that ASP.NET web page use a <form> with "runat=server" attribute, this
is used as the container of any other ASP.NET server controls, and all
those server controls' postback event can be correctly detected if they're
put inside this server-side form tag. Also, there can only contains single
"runat=server" <form> tag in an ASP.NET web page.
For your scenario, if you want to post different data field entries through
different button on the same page, I think you can consider the following
two means:
1. If you're using ASP.NET 2.0, you can utilize the "cross-page post"
feature, this can let you define multiple buttons on a single page and
configure them to postbac k to different url:

2. You can certainly put multiple html <form> tags in a single ASP.NET web
page. However, make sure that only one form has the "runat" attribute set
as "true". Also, for ASP.NET server controls, they can only be put in
"runat=server" <form> e.g.
=======in aspx page========
<body>
...
<form id="form1" runat="server">
you can put ASP.NET server controls here
.........
</form>
<form id="form2" action="other page'>
you can put only pure html elements here
........
</form>
<form id="form2" action="other page'>
you can put only pure html elements here
........
</form>
........

If you have any more specific questions on this, please feel free to post
