{

}

2. Open SalesTable form Events node.

3. Right click the event and Copy Event Handler Method

4. Paste the code in the class you created.

[FormEventHandler(formStr(SalesTableListPage), FormEventType::Activated)]

public static void SalesTableListPage_OnActivated(xFormRun sender, FormEventArgs e)

{

    XMA_SalesOrderLoqateAddressList_Table   addressList;  

    FormDataSource  salesTable_ds = sender.dataSource(formDataSourceStr(SalesTable, SalesTable));

    FormControl buttonUpdateConfirmation = sender.control(sender.controlId('buttonUpdateConfirmation'));

    SalesTable salesTable = salesTable_ds.cursor();

    if (salesTable.deliveryAddress == NoYes::Yes)

    {

        buttonUpdateConfirmation.visible(true);            

    }

    else

    {

        buttonUpdateConfirmation.visible(false);

    }

}

5. Right click the form control and copy Event Handler method

[FormControlEventHandler(formControlStr(SalesTable, CopyOfReferenceGroup), FormControlEventType::Modified)]

public static void CopyOfReferenceGroup_OnModified(FormControl sender, FormControlEventArgs e)

{

    FormDataSource  salesTable_ds = sender.formRun().dataSource(formDataSourceStr(SalesTable, SalesTable));

    FormControl buttonUpdateConfirmation = sender.formRun().design().controlName('buttonUpdateConfirmation');

    SalesTable salesTable = salesTable_ds.cursor();

    SalesTable salesTableOrig = salesTable.orig();

   

    if (salesTable.deliveryAddress().RecId != salesTableOrig.deliveryAddress().RecId)

    {

        Error("Error");

        ttsbegin;

        salesTable.deliveryAddress = 555665544;

        salesTable.doUpdate();

        ttscommit;

        sender.formRun().reload();            

        buttonUpdateConfirmation.visible(false);            

    }            

}
