Hello Friends,

I am new in AX2009 and Dynamic user group…

This is my first post. Please can any one help me.

I have start the learn Ax from last month, but i cant understand method (Form, Reports & class all these thing)

means when which method is called, when which method is used, when write a code on which method and so on…

Please help me as early as possible…

Thanks

Hello Monika,

The use of the methods in different Forms, Reports can only be done only by practice…so not just read the theory books…but find some good task from different blogs and try to learn from them…

Thanks & Regards

Hello Monika,

You can learn about methods in axapta…just have a look at the link which is given below…

Sequence of execution of methods

The nature of the user interface in MorphX is event driven. This means that when an event recognized by MorphX occurs, the X++ programmer can modify the system’s default behavior if necessary. A table does not have a visual representation on it’s own. The only way to work with the data in your tables through the user interface, is through a form. Both forms and tables have methods that are executed in response to the actions performed by the end user. Below are descriptions of typical sequences of events that occur in a normal MorphX application.

When the end user… This sequence of table methods is called…

runs a form which is using a table as a data source. ----- HelpField

inserts a new record via a form using CTRL+N ----- InitValue

Jumps from field to field when entering data in a record by using the Tab key ----- ValidateField, HelpField

Enters a new record via a form and leaves the current record, for example,

by using the arrow keys to move to the next line in a grid ----- ValidateWrite, Write, Insert

Modifies an existing record via a form and leaves the current record,

for example, by using the arrow keys to move to the next line in a grid ----- ValidateWrite, Write, Update

places the mouse pointer over the current field in the current record in a form ----- TooltipField

Form :

This gives the information of method calls in the form level while

  1. Opening the Form.

  2. Creating/Updating/Deleting the record in the Form.

  3. Closing the Form.

Sequence of Methods calls while opening the Form

Form — init ()

Form — Datasource — init ()

Form — run ()

Form — Datasource — executeQuery ()

Form — Datasource — active ()

Sequence of Methods calls while closing the Form

Form — canClose ()

Form — close ()

Sequence of Methods calls while creating the record in the Form

Form — Datasource — create ()

Form — Datasource — initValue ()

Table — initValue ()

Form — Datasource — active ()

Sequence of Method calls while saving the record in the Form

Form — Datasource — ValidateWrite ()

Table — ValidateWrite ()

Form — Datasource — write ()

Table — insert ()

Sequence of Method calls while deleting the record in the Form

Form — Datasource — validatedelete ()

Table — validatedelete ()

Table — delete ()

Form — Datasource — active ()

Sequence of Methods calls while modifying the fields in the Form

Table — validateField ()

Table — modifiedField ()

When you open a report, the following methods are called in the order that they appear in the table.



Method

Description


init

Initializes the report and its objects. This is the earliest method that can be overridden among those executed when a report is constructed and run.



Override this method to add initialization tasks, such as the following:

- Validation of the argument objects received


- Initialization of supporting classes


- Dynamic changes to the design




If your changes require access to the objects of the report, add your code after the super() call.



Caution noteCaution
Do not delete the super() call from this method. The super() call initializes all the objects of the report.


run

Runs the report. This method is executed when the user clicks OK on the preliminary specification dialog box of the report (which enables the user to select where to send the report, and so on).



The default version of this method does the following in the sequence shown:

1. Calls prompt.


1. Creates a basic design if it does not already exist.


1. Arranges the fields.


1. Calls fetch.


1. Calls print.


prompt

Prompts the user to select a print medium and other information.



Available mediums include paper, the screen, a print archive, .rtf, HTML, ASCII, .pdf, and text (UTF-8).



To disable the print medium selection, override the method, and then remove the call to super().



Caution noteCaution
Do not mistake this method for the method of the same name on a query.


fetch

Fetches records from the database. The fetch method instantiates a query, opens the query prompt, and then fetches the records.



During the execution of the fetch method, the next and get methods are executed in pairs on the query of the report. The send, the header and/or footer methods, and the progressInfo method are then executed. The cycle continues with calls to next, get, and so on, until all the data has been fetched.



The following are reasons for overriding the fetch method:

- The report is not based on a query.


- Some of the fetched data must be processed (this can also be done on the send method).


- The report is based on a temporary table.


print

Prints the report to the selected print medium, such as a printer, file, or screen.
