Thank you for attending our webinar: Developing with JavaScript for Dynamics 365 BC.

The webinar overviewed these practices and steps:

1. Adding control add-in
Add control add-in to the page and set up the necessary setup.
2. Invoking events
JavaScript lets us modify Dynamics 365 Business Central page – modify the page to create on load event – message.
3. Factbox control add-in
Create a factbox-control add-in page in order to add it to any page.
4. Embedding customer‘s Home page to FactBox
Improve our add-in with the customer’s home page. This shows how to transfer information from NAV to Javascript.
5. Managing add-in with NAV actions
Not wanting to load the page on every customer? Let’s create an action for loading it.
6. Managing add-in with Javascript Buttons
Let’s go even further – auto-create buttons in control add-in to load our webpage. This part shows how to create buttons to communicate back to Navision.

Please find all questions and answers below

Q: Can JavaScript be done in a Cloud version?

A: Yes, it can. Actually, JavaScript replaces .net in a Cloud version.

 

Q: Is there any CSS that would help to look like buttons in NAV?

A: You have to search for it. Just enter ‘Business Central CSS guidelines’ and you can find plenty of examples.

 

Q: Is it possible to change the appearance of the standard NAV controls?

A: Now, no. You can only manage what is inside of your control add-in. Everything outside these values is not accessible and you can’t manage it.

 

Q: Can user input data be returned from control add-in?

A: Yes, it would be in a similar manner as creating a button callBack, but you would need to create form (or other HTML means to do that) object.

 

Q: Can we use frameworks like the knockout, angular?

A: Yes, you can do that.

 

Q: Are there any licensing restrictions on control add-ins?

A:  Not that I am aware of.

 

Q: Do you have to install JavaScript language in VS Code to be able to create JS script?

A: No, there is no need for the installation.

 

Q: Can we use JS as ping pong in old NAV?

A: Yes, you can do that. You just create a loop of calling back and forth to NAV. Also, you need to create a delay period, and you need to do that in HTML modification, but it’s completely possible.

 

 

Q: Can we use external CSS files like bootstrap?

A: Yes, it should be possible. You just have to provide the correct links to it on the control add-in setup.

 

Q: Is there a possibility to access data from other records (for example Setup) from within JS by using callback or something like that?

A: Yes, you can do that. If you look at the code, you can see that here you can create additional fields, options, data, buttons, etc. Also, you can create a full communication between JS, control add-in and NAV.

 

Q: How to control the order and position of the object in the control?

A: Please check HTML guidelines on that. You should be able to find a lot of information on this topic.

 

Q: Can we debug the JS code?

A: No, we can’t debug it, but we can investigate how it’s created. If you go to ‘More tools’ -> ‘Developer tools’, you can check how it’s created and you can inspect every element. But for now, Business Central NAV doesn’t allow you to debug it.
