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);
    // 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 

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;
    // string to container
    con = str2con(element.args().parm(),'','');    
    // for sorting
    for(i = 1;i<= conLen(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;
    if (element.args() && element.args().caller() && element.args().record())
        helper= MultiSelectionHelper::createFromCaller(element.args().caller());        
        fieldstr(CustTrans, RecId));



Happy Daxing 🙂
