Pass multiple records from one form to another

I came across a requirement to pass multiple records from one form to another. It might would be a very common practice now. However, I thought to blog it for if anyone still not cleat with this part.

Instead of passing datasource as an argument in the property, Override clicked() method of button and prepare your args to pass as shown. I am taking an example of SalesTable to pass to another form

void clicked()

{

    int         recordsCount;

    SalesTable  salesTable;

    container   con;

    Args        args;

    str         multiSelectString;

    args = new Args();

    // gets the total records selected

    recordsCount = salesTable_ds.recordsMarked().lastIndex();

    salesTable= salesTable_ds.getFirst(1);

    while (salesTable)

    {

        // storing recid of selected record in container

        con = conIns(con,1, salesTable.RecId);

        // converting container to string with comma separated

        multiSelectString = con2Str(con,’,’);

        salesTable= SampleTable_ds.getNext(); // moves to next record

    }

   

    // passing string

    args.parm(multiSelectString);

    // calling menu item

    new MenuFunction(menuitemDisplayStr(NewFormMenuItem), MenuItemType::Display).run(args);

}

Now in the above method we have already prepared our args in a container and have passed that to a new form of menu item "NewFormMenuItem"

In order to retrieve passed arguments in the recipient from. Override the init() method of new form as shown

public void init()

{

    container   con;

    int         i;

    str         multipleRecords;

   

    super();

   

    // to get string value from caller

    multipleRecords = element.args().parm();

    // string to container

    con = str2con(multipleRecords,”,”);

    // for sorting

    for(i = 1;i<= conLen(con) ;i++)

    {

        salesTable_ds.query().dataSourceTable(Tablenum(SalesTable)).addRange(fieldNum(SalesTable,RecId)).value(SysQuery::value(conPeek(con,i)));

    }

} 

If you have some more improved versions of this task please share.

Happy DAXing!
