Accepted answer
you said your dropdown is inside the update panel, then try like this

in you aspx:
declare one hidden field

in your code behind:

protected Boolean Validation()
{
if (ddlCarSegment.SelectedIndex == 0)
{
HdnIsToolTip.Value="Yes";
return false;
}
}

i made a mistake without adding document ready

$(document).ready(function () {
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
alert('i enter1');
var hdnIsToolTip = $("#<%= HdnIsToolTip.ClientID %>").val();
if (hdnIsToolTip == "Yes") {
alert('i enter');
ddlcar();
}
});
});
now iam not getting the error ,the alert ('i enter1) is firing on index change but the alert i enter in not working ,breakpoint is also coming to the part if (ddlCarSegment.SelectedIndex == 0)
{
HdnIsToolTip.Value="Yes";
return false;
}

i tried as u had said its not working,i inserted alertboxes inside ddlcar() and also inside var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
var hdnIsToolTip = $("#<%= HdnIsToolTip.ClientID %>").val();
if (hdnIsToolTip == "Yes") {
ddlcar();
}
}); they are also not firing. in inspect element iam getting Uncaught ReferenceError: Sys is not defined
