Hello,

Using FormControlEventHandler, do I need to call the form method. I need to call the PurchEditLines.purchFormLetter(). How can I do this?

[FormControlEventHandler(formControlStr(PurchEditLines, OK), FormControlEventType::Clicked)]
public static void OK_OnClicked(FormControl sender, FormControlEventArgs e)
{
FormRun formRun = sender.formRun();
FormDataSource purchparmtable_ds = sender.formRun().dataSource(/PurchParmTable/);
purchparmtable purchparmtable = purchparmtable_ds.cursor();

// PurchFormLetter purchFormLetter =

// TODO

}

FormControlEventHandler - How to call the form method (PurchEditLines)?

Trying to put business logic to clicked() is usually a bad approach and it's indeed the case here.

The OK button is a command button. It has no code in clicked(); the F&O kernel executes the command, which is closing the form. Then kernel executes a few form methods like canClose() and closeOK() (you can see existing business logic of PurchEditLines form there). Therefore you should create an extension of PurchEditLines form and extend a method like closeOK() with CoC. And there you can simply refer to purchFormLetter by name.

Hi Shooowtek,

Is this method in form level?

If yes, then you already defined formRun which is the form for your control.

So would formRum.purchFormLetter() work?

Thanks,
