Crud Controller Notification display

Question

Hi (again),is it possible to return notifications from the CRUD Controller of Schedule?Let's say an insert action is validated server side only and cancelled, or an exception has been thrown - how could present a message to the user? I thought I might be able to "hijack" the reminder boxes but it does not seem possible that way.Thanks very much, I hope you can point me into the right direction.

Hi Stefan, 
 
Thank you for contacting Syncfusion support. 
 
We would like to inform that currently there is no option to notify the user if the request fails, kindly validate the request at server side and alert the user

I have now solved this using SignalR and PNotify. I've written a short overview on the How on Stackoverflow if anyone is interested.

Hi Stefan, We are happy to hear from you. As said earlier there is no default option to alert the user on request fail. We have performed the CRUD operation on Ajax post to alert the user which can be download from the below location. http://www.syncfusion.com/downloads/support/forum/133482/ze/Sample-1842379662

    args.cancel = true; var UserData; 
    if (args.currentAction == "add" || args.type == "beforeAppointmentCreate") { 
        var appoint = []; 
        appoint[0] = !(ej.isNullOrUndefined(args.appointment[0])) ? args.appointment[0] : args.appointment; 
        UserData = { "added": appoint, "changed": null, "removed": null }; 
    } 
    else if (args.currentAction == "edit" || args.currentAction == "editSeries") { 
        var appoint = [];
