linkbutton same as command button?

[Joe]

The linkbutton seems to add javascript code
<script language="javascript"><!-
function __doPostBack(eventTarget, eventArgument)
var theform = document.WebForm3
theform.__EVENTTARGET.value = eventTarget
theform.__EVENTARGUMENT.value = eventArgument
theform.submit()

// --></script

and end up in the form collection __EVENTTARGET with the naming: UserControlName:ComandNameThatIAssigned

The button control ends up in the form collection by itself: UserControlName/ID:ComandNameThatIAssigned and has no javascript added to the page?
