Create Yes/No Message Box in X++

During your form or report development you might require response Yes/No from user in order to start any action. In this topic, i will show you on how to create a Yes/No message box to get user response in X++.

In your void main() function you need to write code as below:

1. DialogButton diagBut;
2. str strMessage = "Do you want to print Debit or Credit Note? Click Yes for Debit Note., No for Credit Note.";
3. str strTitle = "Report Selection";
4. ;
5. diagBut = Box::yesNo(strMessage, DialogButton::Yes, strTitle);
6. if(diagBut == DialogButton::No)
7. {
8. //your own code when user click on No button
9. }
10. if(diagBut == DialogButton::Yes)
11. {
12. //your own code when user click on Yes button
13. }

Now, I will explain above code line by line for you to understand easily.
