Title: Resetting loc:Alert
Post by: Koen Tjoa on November 16, 2011, 01:58:56 PM

Hi All,

In a button on a NetWebForm I do some checking. If an error occurs, I would the message to appear just below the sub heading. So set loc:Alert = 'Oops, this is not good'. The code is in the Validate::MyButton Routine. When the error occurs loc:Alert is set, followed by a call the SendAlert routine and then an exit from the routine is done preventing the rest the code to process.

This all is working fine except that loc:Alert isn’t reset if the user click another button, selects a record, etc. I guess I can clear and the call the SendAlert routine in the Validate::OtherControl Routine of all other controls, but there might be a better solution.

My code is:
Validate::MyButton  Routine
  IF p_web.GSV('Oops') = 1
    !loc:invalid = 'MyButton'  Seems to make no difference
    !MyButton = true
    loc:Alert = 'Oops, this is not good'
    DO SendAlert
    EXIT
  END
  ! End of "Validate New Value"
  If p_web.RequestAjax = 1 and p_web.ifExistsValue('NewValue')
  ElsIf p_web.IfExistsValue('Value') !FormFieldPicture =   !FieldPicture =
  End
  do ValidateValue::MyButton  ! copies value to session value if valid.
  do Value::TabArg  !1
  do Value::TabArgT  !1

Cheers,
Koen

Koen,

Hi there.

I'm not sure if you left this out or not, but when you are setting things invalid, as well as loc:invalid, the next line you need:

MyButton:IsInvalid = true

Rather than "MyButton = true".

the two lines you commented out are important.

Hi Stu and Bruce,

I tried but it adding those two lines. But they seem to make no difference in case the control is a button like it would be on a (numeric) field. Although loc:invalid and loc:Alert are cleared when another button or a new record in the browse control is selected, the message line just below the sub heading isn’t. That is what I would like to happen.

So I added DO SendAlert in the Validate::XXX routines of these controls. I guess this the way it should be done after all.

Cheers,
Koen
