How to modify standard page layout using extension

15

In this blog we will see how we can modify  standard page by adding few fields and modify property of existing fields.

Adding customize fields in page layout 

For this I assume table extension is already created and now would like to add fields in page layout by creating page extension

In page layout for adding fields you can mention whether you want add fields before/after specified fields or addfirst/addlast in page.

In following example I am adding fields after field VAT Prod. Posting group

pay1

Once you press Shift+F5 then you can see result in page as follows.

pay2

Modifying existing  fields properties  in page layout 

One can modify properties of existing field using modify option in page extension

In this example changing visible property of one of the field in page as per below example

Original page display the field as below

pay3Now we would like to hide this field using visible property so in page extension you can write as below

pay4

Even you can add trigger and write you routine to execute.

Add Action in Page Layout

For adding action once can write following

Here is the result in client.

Hope this help and stay tuned for more.

How to Protect IP Code in Business Central

15Now I know you already started developing app using VS Code and now questions is that how to protect app for viewing the code while debugging or downloading.

However extension development package provide setting for IP protection for viewing or downloading the code of extensions but you can also control by just adding one line code  in app.json file.

app.json file containing setting called showMyCode which controls whether it is possible to debug the code ,By default it is set to false which means debugging in extension code not allowed.

If you want to allow to show extension code then add the line as below in app.json file as by default this setting is not added in app.json file when it is created.

appjson

By adding this setting, you enable debugging into an extension to view the source code when that extension is set as a dependency.

Stay tuned for more.

 

 

 

How to Retain data after publishing App

15

Hope you all started app development and may be wondering how to retain data after publishing app or debugging several times or after adding more sample data.

How do I retain the sample data so every time no need to add the same data.  ?????

In Business central you can synchronize the sample data while publishing several times. This can be done by simple settings in launch .json file.

lanuchjson

Once you mention this settings then the  data synchronize is controlled by this settings.

This settings consist of two options i.e. Synchronize and Recreate .

The default value is synchronize which means data will be retain every time when the app get published.

When schemaupdate set to Recreate mode then all the tables and table extensions are recreated every time and data will get lost.

When schemaupdate set to Synchronize then:

Do’s

  1. Add more field in table
  2. Increase length of field.

Don’t

  1. Don’t delete the field which contains sample data as if the field is removed from table then data can not be synchronize
  2. Don’t decrease the length of field for code and text datatype.

For above points you need to write upgrade code units or set schemaupdate to recreate.

In next blog will see how to write upgrade code units.

User and Workspace Settings in Visual Studio Code

I hope you already started working with Visual studio code.

In this section we will see how to do setting for User and workspace in Visual Studio code environment.

It is easy to configure visual studio code as per your likings using various settings. You can change VS code editor ,user interface and functioning by using this settings

There are three ways you can open user and workspace settings

  1. To access you can go to  Click on File–>Preferences–>Settings

User1user2

2) Using Command Palette(Ctrl+Shift+P)  by typing

Preferences: Open User Settings  or Preferences : Open Workspace Settings

user3

3) Use keyboard shortcut (Ctrl+,)

This provides two different settings

  • User Settings – Settings that apply globally to any instance of VS Code you open.
  • Workspace Settings – Settings stored inside your workspace and only apply when the workspace is opened.

Workspace settings override user settings.

How to create user settings 

Once you open settings then you can modify settings as below

Example. If I want to change font size in editor then I can do it from here

 

Change the font size and see the effect on editor.

user6

It shows the effect immediately after saving the file.

Same kind of settings you can do it for AL language extension management

user7These changes get saved in %APPDATA%\Code\User\settings.json

Hope this will help you while extension development

Stay tuned for more…

Setup Visual Studio Code for local NAV server Installation

In this section we will see how do we setup Visual studio code locally on NAV 2018 server.

Hereby I assume that NAV 2018 is already installed on local machine .

You can download Visual studio code from Visual Studio Code

After Installing NAV 2018 and Visual Studio Code follow following steps to enable Visual studio code for writing extension and AL code.

  1. Enable Developer Service endpoint from NAV server instance

Developer End Point

2) Setup Web Client Base URL

Mention the web client url address .for example :- http://localhost:8080/dynamicsnav110/

WebClientURL

Once all changes done in service then restart the service.

3) Open Visual studio code and Install VSIX file from media 

InstallVSIX

You will find .vsix file in NAV 2018 Media file in folder ..\NAV.11.0.22292.W1.DVD\ModernDev\program files\Microsoft Dynamics NAV\110\Modern Development Environment\ALLanguage.Vsix

This will install AL language in visual studio code

4) Press CTRL+SHIFT+P and select command AL:GO in order to select a location and create a folder with default file of an extension

5) Setup Launch .JSON file

JSOn

Change server instance to DynamicsNAV110 and authentication to Windows

6) Press CTRL+SHIFT+P  and use command to download symbols AL:Download Symbols

7) Pres CTRL+F5 to publish the Helloworld.AL extension which extends customer list page and same id is mention in startupobjectid parameters of launch .json file

AL1

Once publish you will get following in web client

Get ready for extension development with this….

Page Extension -Tenerife Visual Studio Code

In previous post Table Extension we saw how to extend table using Tenerife (New NAV development tool) .In this blog post we will see how to extend Pages using visual studio code.

The page objects extends a dynamics NAV page object .This will used for add or overrides the functionality.The structure of page is divided into three parts

  1. First part contains metadata for the entire page
  2. Second part describes visual parts on page

At the moment Microsoft development tool is still evolving and getting updated day by day.

In this blog post we will see how how to create Table extension object.

The table extension allows you to add more fields or change properties on a table. Along with defining other fields,the table extension is where you can write trigger code for additional fields.

In visual studio code by typing ttableext will create basic layout for table extension object when using AL extension in Visual Studio code.

Following properties can be changed for table

  1. Width
  2. OptioncaptionML
  3. Description
  4. ClosingDates

How to Write Code 

For example now if you would like to add one field in table and write some validation on that field then you can write as follows. In this I am adding field in Table 23 Vendor as Credit Days with datatype Integer.

tableextension 70000030 CreditDays extends Vendor
{
fields
{
field(70000900;CreditDays;Integer) 
{
trigger OnValidate();
begin
if (rec.CreditDays < 0) then
begin
message('Credit Days can not be blank');
end; 
end;
}
}
}
