Pass the Data Source records to Class or pass the multiple records to class refresh also in AX 2012 / Dynamics 365

LOOP THROUGH SELECTED RECORDS OF A GRID

1. Add a action MenuItem in a form as a MenuItemButton.
2.Take a clicked method()

void clicked()
{
MenuFunction mf;
args args = new Args();
;
args.record(Table1);
mf = new menufunction(identifierstr(classParmData), MenuItemType::Action);
mf.run(args);
}

3.Take a class

class ClassParmData
{
Table1 tb1;// table variable declaration
}
----
public static void main(Args _args)
{
ClassParmData parmData;
Table1 table1;
FormDataSource fds;
;
if(args.record().TableId == tablenum(Table1))
table1 =_ args.record(); // assigning the selected record

fds = _table1.dataSource();// getting the datasource

parmData= new ClassParmData(fds); //passing the form datasource to New() method
or
parmData.parmFormDataSource(fds); // passing the form datasource to parm method to use in other methods

/*table1 = fds.getFirst(); // can loop all the record here also
while(table1)//fds.getNext())
{
info(strfmt(table1.Field1));
table1 = fds.getNext();
}*/

fds.research();// to refresh the form records
}
-----
void new(FormDataSource fdst) // receving the datasource to fdst-FormDataSource
{
;
for(tb1 = fdst.getFirst(true); tb1; tb1 = fdst.getNext()) // fdst.getFirst(True) to select marked records
{
info(strfmt(tb1.Field1));
}
//if you are updating some records in the form write the below line to refresh the data in form.
//fdst.research();
}
void parmFormDataSource(formDataSource fdst)
{
for(tb1 = fdst.getFirst(true); tb1; tb1 = fdst.getNext()) // fdst.getFirst(True) to select marked records
{
info(strfmt(tb1.Field1));
}
//if you are updating some records in the form write the below line to refresh the data in form.
//fdst.research();

}
-----
4. and then select a record in form grid and click a menuitemButton you can see the all datasource records in info.
