How to get multi selected records on the grid / datasource

If you want to acknowledge multi selected records on form . write below code on button clicked
---------------------------------------------------------------------------------------------------------------------------

void clicked()
{
    if (Box::yesNo("Do you want to acknowledge the selected records", DialogButton::No) == DialogButton::No)
    {
        return;
    }
    else
    {
       element.updateAcknowledgementFlag();
    }
}
__ now updateAcknowledgementFlag method will have the multiselected record

public void updateAcknowledgementFlag()



{

afmATPPostalCodeDlvMode aTPPostalCodeDlvMode;

MultiSelectionHelper helper;

helper = MultiSelectionHelper::construct();

helper.parmDatasource(afmATPPostalCodeDlvMode_ds);

aTPPostalCodeDlvMode = helper.getFirst();
  while (aTPPostalCodeDlvMode.RecId != 0)



{
  aTPPostalCodeDlvMode.selectForUpdate(true);



aTPPostalCodeDlvMode.NewZipCode = NoYes::No;
  if(aTPPostalCodeDlvMode.validateWrite())



{

aTPPostalCodeDlvMode.update();

}

aTPPostalCodeDlvMode = helper.getNext();

}

For example, if you want to assign selected records to Set/List/container  in a grid, you could use it like this:

MyTableBuffer            myTableBuffer; MultiSelectionHelper     selectionHelper = MultiSelectionHelper::construct(); // declare set,list and container as per needs Set                      selectedRecords = new Set(Types::Record);          selectionHelper.parmDataSource(myTableBuffer_DS);    myTableBuffer = selectionHelper.getFirst();    while (myTableBuffer) {     selectedRecords.add(myTableBuffer);        myTableBuffer = selectionHelper.getNext(); } -------------------------------------------------------------------------------------------------------------------------- The code above should be very useful when getting the list of selected records directly on the form, but if you want to get the selected records in a class that was called from a form, for example, you could use the MultiSelectionHelper like this:                                                               public static void main(Args _args) {         FormDataSource          formDataSource;         MyTableBuffer           myTableBuffer;     FormRun                 caller = _args.caller();     MultiSelectionHelper    helper = MultiSelectionHelper::createFromCaller(caller);     Counter                 i;        // First we need to get the correct form data source     if(args && args.dataset() == tableNum(MyTableBuffer)) {                 MyTableBuffer= args.record(); }        // We then tell the selection helper object to create ranges for the selected records     helper.createQueryRanges(formDataSource.queryBuildDataSource(), fieldStr(MyTableBuffer, RecId));        // Now we can traverse the selected records     myTableBuffer = helper.getFirst();        while (myTableBuffer)     {         info(myTableBuffer.RecId);  // write / call the methods to execute the business logic here            myTableBuffer= helper.getNext();     } }
