Dialog Validation

I've found several posts and articles around the net talking about validating form fields in dialogs, but none of the examples I've found seem to work properly.

Can someone post a complete, concise example of x++ code that generates a dialog containing a single text field, performs simple validation (if text = "abc") on it, and either closes the window (returning the field value) if validation passes or generates an Infolog warning without closing the dialog if validation fails.

For those of us just beginning in x++, I think it would be a great starting point to have an actual working example to build on.

Thanks!

Hi Brad,

You can start with the following example. Just copy and past it into a new job.

static void DialogJob1(Args _args)
{
    Dialog      dialog;
    DialogField dialogField;
    Name        name;
    ;

    dialog      = new Dialog("please type ' abc'");
    dialogField = dialog.addField(typeid(Name),"Type value" );

    if (dialog.run())
    {
        name = dialogField.value();

        if (name == 'abc')
            info("well done, mate!");
        else
            throw error("This was the wrong value");

        // add code after validation
    }
    else
    {
        warning("Update cancelled by user");
    }
}

regards,

André

Thanks for the hint. Unfortunately, this is what I have now. I'm looking to either validate each field as it is changed or validate the entire dialog at once, but NOT allow it to close if validation fails.

When I do it this way, the dialog closes whether or not validation passes or fails.

Thanks again.

Hi,

In this case you need to create a form as dialog. On the form you can add some validation before closing it. There are some examples in standard AX2009:

Form InventCostReportDialog which is called from report InventCostValue (method Dialog)

Form ProjEstimateListDialog which is called from report ProjEstimateList (method Dialog)

but you can also use a form-based dialog on classes.

regards,

André

you can create a runbase class dialog where on standrad validate method you can validate on fields before the dialog is closed.

Take a look at
\Classes\InventABCUpdate\validate
method for example. There is few dialog fields validation presented.
