explain the concept of extensions

concept of extensions d365

An extension is a way to add functionality to an object in D365FO without modifying the base code of that object.  

Your extensions are compiled into their own DLLs, which are separate from the D365 base system libraries. It also makes it easier for Microsoft to patch their sys layer code.

Microsoft has added to allow customizations without allowing the base code to be changed, because they plan to not allow any overlayering of SYS layer code.

Change number of decimals in D365 finance and operations Dynamcis AX

HI,

IN ORDER TO CHANGE THE NO OF DECIMALS IN ANY FORM IN D365 

YOU WILL FIRST NEED TO CHECK THE PROPERTIES OF THE FIELD AT THE TABLE LEVEL

IN CASE THERE IS ANY EDT ATTACHED TO IT THEN CHECK THE "NO OF DECIMALS" FOR THE EDT .

ALSO IF THE EDT IS FURTHER EXTENDED THEN THE PROPERTY OF THE EXTENDED EDT NEEDS TO BE CHECKED.

THIS WILL ALSO EFFECT THE OTHER FIELDS WHICH ARE ALSO EXTENDING THE SAME EDT.

SO THE BEST APPROCH IS TO CREATE A NEW EDT WITH 5 DECIMAL PLACES AND ASSIGN THE EDT TO THE FIELD IN QUESTION.

THANKS,

 VIKAS MEHTA

ACTIVE METHOD IN D365 FORM DATASOURCE

FORM ACTIVE METHOD IN D365 DATASOURCE EVENT HANDLERS FOR Activated METHOD 

How to get the event handler for the init method for Init method in D365 forms

You can just write the below code in any new class or else if you have an existing one then just simply copy the code in the class.

The class declaration should read:

[ExtensionOf(formStr(FormName))]final class FormName_Extension{}

So if the form name is SalesTable then the code will be 

[ExtensionOf(formStr(SalesTable ))]

final class SalesTable_Extension{}

In some cases even a class without the extension signature i.e. [ExtensionOf(formStr(SalesTable ))] might not be required but in that case  the this object will not provide the objects in the intellisense.

Note that the class declaration is Final and cannot be further extended.

[FormDataSourceEventHandler(formDataSourceStr(Salestable, Salestable), FormDataSourceEventType::Activated)]
    public static void Salestable_OnActivated(FormDataSource sender, FormDataSourceEventArgs e)
    {
        Salestable           Salestable     = sender.cursor();
        FormDataSource      Salestable_ds  = sender.formRun().dataSource("Salestable");
        FormRun             element       = sender.formRun();
        FormControl         myNewButton   = element.design(0).controlName("anybutton");

        anybutton.enabled(false);
    }

}
