Passing the records between the forms Dynamic AX

1.       Create a formA with datasource as CustTable and grid in the design with the same datasource and one button.

2.       Overrode the clicked method of button in FormA

void Clicked()

{

Args    _args;

FormRun _formRun;

AccountNum      _accountNum;

;

_accountNum = CustTable.AccountNum;  // Selected AccountNum in the Grid is assigned to the variable which is pass to the next form

_args = new Args(); // creating a object for args class

_args.name(formstr(CustomerSelectionRecordsA));  // Form Menuitem

_args.caller(this);  // Form Caller(Current Form is mentioned as this)

_args.parm(_accountNum); // Employee Number is passed to next form[but parm() is not a best practise]

_args.record(CustTable); // Table name is passed

_formRun = ClassFactory.formRunClass(_args); //new FormRun(_args);   // Creating object for FormRun

_formRun.init();   // Form Initialization for Load

_formRun.run();  // Form Run for process

_formRun.wait(); // Form Wait for Display

}

3.       

4.       Create another formB with same as formA design.

5.       Override the init() of the formB

public void init()

{

parmid      _parmId;

CustTable   _CustTable;

_parmId =  element.args().parm();

if(!element.args().caller())  

super(); 

}

else

{

info('DataSet Not Received'); 

}

}

6.       Override the init() of the datasource of the form table that we used  ie CustTable

public void init()

{

    Query               query;

    QueryBuildRange     queryBuildRangeProj;

switch(element.args().dataset())// get the table id sent by caller

{

case tablenum(CustTable):  // check the table if matches with this tableid

{

_AccountNum  =   element.args().parm();  // get the argument value

 query   = new Query();

queryBuildRangeProj = query.addDataSource(tablenum(CustTable)).addRange(fieldnum(CustTable,AccountNum));          // query build for the form to display

queryBuildRangeProj.value(_accountNum); // Criteria for the form

CustTable_ds.query(query); // execution of the query

break;

}

}

super(); //datasource  initialization on the form based on the criteria

}

7.       In the class declaration of the form

public class FormRun extends ObjectRun

{

    SysLookupMultiSelectCtrl msCtrl;

    AccountNum   _accountNum   ;

}
