I'm trying to send an sms from c# WindowsPhone7/8 like this:

SmsComposeTask smsComposeTask = new SmsComposeTask();
smsComposeTask.To = smsPhonenumberToSend;
smsComposeTask.Body = smsMessageToSend;
smsComposeTask.Show();

this works, the sms is sent, but after the user accepts (or declines) to send the sms I want to do some calculation in code behind.

Is there a way to attach some callback method and fetch the status of sms composer task?

If this can't be done by the SMScomposer, please guide me if there is any other way in WP to send and sms and get info if it was sent or not.
