Form Notification subscriber - cancel/abort submit

Hi everyone,

I'm using the subscriber: [Subscribe(Dynamicweb.Forms.Notifications.Frontend.OnAfterSubmitSave)]
And what I'm trying to accomplish is to validate an email on form submit and if the email doesnt comply with my criteria, i wish to cancel the submit somehow. The only option I can find that seems to somewhat do what I want is:
 

if (args == null || !(args is Dynamicweb.Forms.Notifications.Frontend.OnAfterSubmitSaveArgs))
{
      return;
}

 Dynamicweb.Forms.Notifications.Frontend.OnAfterSubmitSaveArgs submitArgs = args as Dynamicweb.Forms.Notifications.Frontend.OnAfterSubmitSaveArgs;


 submitArgs.Submit.Delete();

Is this the only way or is there a better way to 'cancel' the submit if a condition is met?

Hi Nicholai

Hope life treats you well out west!

You can use a Notifications.Frontend.OnBeforeContent notification which gets passed a Notifications.Frontend.OnBeforeContentArgs object.

That Notifications.Frontend.OnBeforeContentArgs object has a StopExecution property that will skip the form submit.

This notification fires on all form module instances - so also when rendering a form.

So inside your notify method, do something like this to detect a submit:

if (!string.IsNullOrEmpty(RequestContext("cmd")))
{
    if (RequestContext("cmd").Equals("save", StringComparison.OrdinalIgnoreCase))
    {
        //Check the email address and fail if it is not ok:
        (Notifications.Frontend.OnBeforeContentArgs)args.StopExecution = true;
    }
}
