In BEFORE, you have a hook where you can determine pragmatically if row
change should be allowed, return .F. and the change doesn't happen.
Yup. I want to use the values in the row to determine whether
to allow the row to change.
curval() doesn't get the new value until Valid() fires and returns .T.
I am not concerned about the value for an individual
control. That I have working. Where I am having difficulty is with
the row-level validation.
There's a tool you can use to follow the event firing sequence. Somebody
else ought to be able to chime in with the name.
Finally, i think you can use AFTER to capture the values you're looking for
and effectively use it as a row-level Valid().
But that would mean that the row change would occur. If there
is an error in a row, I do not want the row change to occur.
There has been some good writing on these events. Maybe somebody can
recommend the article, paper or book?
Please, yes. Grid is not documented very well globally.
