Hi All,
In this blog we will learn how to get all selected records from form grid or form data source in event handler.    

X code.

[FormControlEventHandler(formControlStr(LedgerJournalTransCustPaym, UpdateOffsetDimension), FormControlEventType::Clicked)]

public static void UpdateOffsetDimension_OnClicked(FormControl sender, FormControlEventArgs e)
{
    FormRun                 formRun  = sender.formRun();
    FormDataSource          ledgerJournalTrans_ds;
    LedgerJournalTrans      ledgerJournalTrans;   
    ledgerJournalTrans_ds = formRun.dataSource(tableStr(LedgerJournalTrans));

    MultiSelectionHelper  selectionHelper = MultiSelectionHelper::construct();

    selectionHelper.parmDataSource(ledgerJournalTrans_ds);

    ledgerJournalTrans = selectionHelper.getFirst();

    while (ledgerJournalTrans)
    {
      info(ledgerJournalTrans.Voucher);
        ledgerJournalTrans = selectionHelper.getNext();
    }
}
