Short answer?

1) Mouse movement can cause this behavior, though I have seen this behavior
with a laptop touchpad clicking the button, not tapping.

2) Buffering

Subject: Checkbox in Grid oddities.


Anyone else ever had strange issues using a checkbox in a grid?
Specifically, the column with the checkbox is used as an Include or
Select? column to designate which records to choose for some
processing. I got it working fine, but...

I've noticed the following strange behaviors:

1) Sometimes when you check the checkbox, it doesn't seem to toggle
the value, even though you clearly clicked it. Most of the time, it
works as expected.

2) In the header click of the column, I am replacing the value of the
field with the !value of the field, so as to toggle all selected,
none selected.
This works fine, but strangely, if you first click a record, say it
turns to checked AND DO NOT move to the next row, clicking the
header, seems to suggest the value of the control source is never
updated, as all records are then checked, where as it should have
been all records are checked except the 1st one that you had already
checked. That one should have been 'toggled' off..All columns are
readonly .f., except this one.
IF after clicking the 1st record to checked, I move to a different
record next, THEN click the header, all records are properly toggled
checked, with the 1st record toggled off.

I checked the grid class that this form's object is based on, and
there's no code there to be causing this kind of problem. There's no
code at all except to set the sparse, readonly, ,enabled, and control
source properties at the init of the grid.

Anyone have any ideas what's going on here? I don't have the time to
really trace through this much as I've higher priority things to deal
with first..

Thanks-
Steve
