postback

[vinay]

when will the page create a JS for postback??
I am trying to handle it manually, it wont find the function??
__doPostBack('b tnSearch','');

Is that function generated after a postback??
Is there anyway to generate it on load??

<script language="javas cript">
<!--
function __doPostBack(ev entTarget, eventArgument) {
var theform;
if (window.navigat or.appName.toLo werCase().index Of("netscape") > -1) {
theform = document.forms["baseForm"];
}
else {
theform = document.baseFo rm;
}
theform.__EVENT TARGET.value = eventTarget.spl it("$").join(": ");
theform.__EVENT ARGUMENT.value = eventArgument;
theform.submit( );
}
// -->
</script>

To my knowledge you can't generate the postback script yourself.
However, if your intent is to intercept the postback for e.g. a button,
you can register a script for that button prior to execution of
postback (using the controls Attributes member).

In the javascript you can then decide whether you want the postback to
fire or not (setting e.Cancel = true or false)
