How to take user input using C/AL in NAV 2016?

Question

Suppose I want to write a simple addition program using C/AL in NAV 2016. How can I dynamically ask user to enter the two numbers?

In Microsoft Dynamics AX we use "dialog" class for this purpose.

I need some code reference or the description to approach such process.

Answer 1

In Dynamics NAV do not have something like Dynamics AX dialog class.

In this case you need create a page with your fields to user complete the info. Then in other page call this new page to open it and the user can complete de info or add in MenuSuite to access.

Example:

Page 88000 Calculator

Variables

Action and Action code

Page running

Then you can create a menuSuite for this page or write this code in other page to open it

PAGE.RUNMODAL(88000);

Answer 2

You can use

1. Page object as described in other answer. But to get values from it to calling function you would need to create source table for that page. Or throw some function to it like GetValues.
2. Use dialog.input. It may be obsolete though.
3. Use dialog class from windows .net library. Will not work in web client though.
4. Depending on situation report’s request page might be a good option.
