<p>Details:</p>

<ul>
<li>Only disable after user clicks the submit button, but before the posting back to the server</li>
<li>ASP.NET Webforms (.NET 1.1)</li>
<li>Prefer jQuery (if any library at all)</li>
<li>Must be enabled if form reloads (i.e. credit card failed)</li>
</ul>

<p>This isn't a necessity that I do this, but if there is a simple way to do it without having to change too much, I'll do it. (i.e. if there isn't a simple solution, I probably won't do it, so don't worry about digging too deep)</p>

in JQuery:
```
```
$('#SubmitButtonID').click(function() { this.disabled = true; });
```
```
