Postback after carriage return input

I have a WebForm with one control: A HTML INPUT control
with the property "runat=server" set. If this page is
running and I set the cursor in this control and
enter "Carriage return", the page does a roundtrip
(postback) to the server (which I doesn't want). If I
include a second HTML INPUT control on this page,
entering "Carriage return" does no postback.

How can I prevent a postback, if the user enters "CR"?

Thanks for an answer.

You shouldn't stop this functionality, because it is common
functionality in web browsers, users expect this behavior.

You can however stop it by doing <input type="text" onkeydown="return
event.keyCode==13">

It may be a common functionality in web browsers, but it can play havoc with
an ASP.Net WebForm. It is important to anticipate and handle this event.

In reality my WebForm needs, in addition to a few
listboxes and textboxes, several buttons to execute
different functions on the server. The return key will do
a click event on the first button (what ever the first
button is), but this is not what the user wanted to do.
The only solution to overcome this problem is to use HTML-
buttons instead of Server-buttons. Is there a better
solution for that problem?

Hi Ferdi,

Based on my research and experience, I do not think that there is a better
solution.

Hi Ferdi,

I have another simple idea for your reference. That is disable the
onkeydown event of this button. The following is the code snippet:

<INPUT id="Button2" style="Z-INDEX: 102; LEFT: 248px; WIDTH: 88px;
POSITION: absolute; TOP: 96px; HEIGHT: 24px"
type="button" value="HTML Control" name="Button2" runat="server"
onkeydown="return false"></FONT>

Does it answer your question? If I have misunderstood your concern, please
let me know.
