Dear Vixens and Reynards:
I have row-level grid validation that works (so far). I will
be doing some further testing to try to break it, but I think might
finally have my main problem solved.
It is kludgy and will have to be reworked to remove explicit
object references.
I have to check that the underlying table is updated properly,
and I am going to clean up my proof-of-concept code so that it is
usable. After that, I will probably post it.
My approach is to shadow the values for a row.
Grid Level
----------
Declare an array of shadows.
When the grid is being set up, size the shadow array appropriately.
In AfterRowColChange, fill the array from the *data source*.
In BeforeRowColChange, validate using the shadow values not the
control values.
Input Control Level
-------------------
After validating a value, copy it to the appropriate shadow.
Sincerely,
Gene Wirchenko
