Gene, back in April last year you were asking if anyone could write
code to your specification regarding the grid problems you were
having. I don't recall ever seeing your specification, maybe if you
posted it someone might be able to do the code for you.
At that time, I was also having difficulties posting to the
list. I thought I had come up with something, but maybe, it did not
make it and I mistakenly deleted it. Let me specify something simple:
Consider a cursor or table of:
thetext c(20)
evennr n(3)
weirdnr n(3)
The validations are:
thetext>""
evennr%2=0
weirdnr%3=0
and the row-level validation is:
asc(thetext)%2=weirdnr%2
When a control-level validation error occurs, throw an
appropriate message box and then set focus to the control with the
erroneous value.
For a row-level validation:
1) All control-level validations should be done first. Start with
the current control, then do all the others from left to right. The
first that fails gets the message box, and checking stops.
Then, do the row-level validation. If it fails, throw an
aoppropriate message box and then set focus to the control in the
first column from the left of the values that are checked. (In the
example above, thetext is left of weirdnr, so set focus to thetext.)
Part 2:
The columns can now be rearranged in any order. Despite this:
The coontrol-level validations should still set focus to the
correct control.
The column-level validations done at the start of the row-level
validation should be done in the order current then
left-to-right. NOTE THAT THIS COULD NOW BE A DIFFERENT ORDER.
The row-level validation should still set focus to the leftmost
involved control. NOTE THAT THIS MIGHT BE A DIFFERENT
CONTROL. (Example: If weirdnr gets moved to the left of thetext,
row-level validation failing should set focus to weirdnr.)
This is basic functionality that I want/need. I have been
unable to get this to work with VFP's Grid despite my efforts.
