Engineer / Solution Architect / Dynamics 365-AX Technical Consultant / Instructor (MCT)

In my practice, I was asked a number of times to create various application functions that
process user-selected records in a form grid. Regardless of what function is being created, the
first step was always to determine what records were selected by the user.
In this recipe, we explore several ways of achieving this goal. We will modify the Items form
in the Inventory management module by adding a new button to it, which lists currently
selected records in the overview grid.

Dialogs are a way to present users with a simple input form. They are commonly used for
small user tasks like filling in report values, running batch jobs, presenting only the most
important fields to the user when creating a new record, etc. Dialogs are normally created
from X++ code without storing actual layout in AOT.
The application class Dialog is used to build dialogs. Other application classes like
DialogField, DialogGroup, DialogTabPage, and so on, are used to create dialog
controls. One of the common ways is to use dialogs within RunBase framework classes that
need user input.

Briefly, Extensible Markup Language (XML) defines a set of rules for encoding documents
electronically. It allows creating of all kind of structured documents. In Dynamics AX, XML
files are widely used across the application. For example, user profiles can be exported as
XML files. Business data like financial statements can also be exported as XBRL (eXtensible
Business Reporting Language) files, which are based on XML.

Copying a record
I’ve experienced that one of the tasks often used when manipulating data is record copying.
For various reasons, an existing record needs to be modified and saved as a new one. The
most obvious example could be when a user requires a function that allows him or her to
quickly duplicate records on any of the existing forms.
There are several ways of copying one record into another in X++. In this recipe, we will explain
the usage of table data() method, global buf2buf() function, and their differences. As an
example, we will copy one of the existing customer records into a new one. Normally, copying
a customer involves more data around the customer like customer contacts, bank accounts,
printing settings, and similar, but for demonstration purposes, we will assume that our goal is
only to copy the customer record itself without worrying about related data.

Merhaba

Buton ile bir formdan başka bir forma geçtiğinizde diğer forma otomatik olarak önceki form nesne olarak aktarılır. Şöyle örnekleyelim. A formundan bir buton ile B formunu açtınız. B formunda bazı değişikler yapıp kapatırken A formunun bir metodunu çağırmak istiyoruz. Örneğin yenileme işlemi yapan bir metodunu çağıralım. Bu işlemi Args nesnei sayesinde yapabiliyoruz.

B formunun ClassDecleration metoduna şu değişken tenımını yapalım;

object callerForm;

B formunun init() metoduna şu kodu ekleyelim ;

callerForm = element.args().caller();

Artık A formu elimizde isteğimiz yerde bildiğimiz herhangi bir metodunu çağırabiliriz.

A formunda veri kaynağını güncelleyen bir metod olsun

void FDRefreshDS()
{
veriKaynagi_DS.executeQuery();
}

B formunun close() metoduna A formunun FDRefreshDS() metodunu çağıran bir kod ekleyelim.

callerform.FDRefreshDS();

Böylece açtığımız formdan bir önceki forma ulaşmış olduk.

Selamlar.
