How to pass more than one record between two forms?

I come through one client requirement to pass multiple selected records from one form to another,The Scenario is when user opens Form-A, selects multiple records and then clicks a button that opens Form-B. there Form-B will receive only those selected records at Form-A.

There are multiple ways to pass single selected record and we can also pass multiple records through container or temporary table for instance:

Write below code on clicked event of menu item button on Form-A which will open Form-B,This is typical and traditional way to achieve this requirement in all versions of AX.

int         recordsCount;
CustTrans custTrans;
container   con;
Args        args = newArgs();

// gets the total records selected
recordsCount = custTrans_ds.recordsMarked().lastIndex();
custTrans= custTrans_ds.getFirst(1);
while(cusTrans)
{
    // storing recid of selected record in container
    con = conIns(con,1, custTrans.RecId);
    custTrans = custTrans_ds.getNext(); // moves to next record
}   
// passing container converted to string 
args.parm(con2Str(con,','));

Then on Form-B, we need to override the init() method to receive the args that we created on clicked event

public void init()
{
    container   con;
    int         i;
    super();       
    // string to container
    con = str2con(element.args().parm(),'','');    
    // for sorting
    for(i = 1;i<= conLen(con) ;i++)
    {
        custTrans_ds.query().dataSourceTable(Tablenum(custTrans)).
       addRange(fieldNum(cusTrans,RecId)).value(SysQuery::value(conPeek(con,i)));
    }
} 

In Dynamics AX 2009,MultiSelectionHelper class is introduced but commonly used in AX 2012 on multiple places, we can write minimal code to achieve the same.

Enable the multi-select property to Yes and on Form-B, we need to override the init() method to load the selected record at Form-A

public void init()
{
    MultiSelectionHelper helper;
    super();       
    if (element.args() && element.args().caller() && element.args().record())
    {
        this.query().dataSourceTable(tableNum(CustTrans)).clearDynalinks();
        helper= MultiSelectionHelper::createFromCaller(element.args().caller());        
        helper.createQueryRanges(this.query().dataSourceTable(tablenum(CustTrans)), 
        fieldstr(CustTrans, RecId));
    }
}
