Exemplo de como tratar erros ocorridos em postbacks assíncronos em asp.net
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args) {
if (args.get_error() != undefined && args.get_error().httpStatusCode == '500') {
var errorMessage = args.get_error().message
args.set_errorHandled(true);
alert('"' + errorMessage + '" '); //Tratar o erro aqui, para exemplo é exibido apenas um alert
}
}

Já ví várias gambiarras soluções mirabolantes para registrar um arquivo javascript em uma página Asp.Net, de forma que ele funcione em qualquer url que o cliente esteja.
Segue um exemplo da forma mais simples que eu já encontrei:
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Js/jquery.js" />
<asp:ScriptReference Path="~/Js/custon.js" />
</Scripts>
</asp:ScriptManager>
