Hi

In a Grid, I have placed a CheckBox with a graphic style

When the user clicks on the CheckBox, a second form is opened to introduce additional data.

The controlSource of this CheckBox is a logical field. In the picture of the CheckBox I have placed
a red image and at the DownPicture is a green image.

What I need is that once the CheckBox "turns" green, it will/should never again turn red
and normally this is for each grid entry.

For example, assume I have 10 entries in the Grid, in 2 of them I have already filled in
the extra fields, therefore the CheckBox appears green, whilst the other 8 are with unfilled fields so
the CheckBox will be red.

At the red CheckBox I am allowed to click to open a new form, but if I click the green Checkbox, nothing
should happen and the CheckBox should still maintain green.

I have already tried placing a NODEFAULT at the click and at the interChange, but this still does not work.

The auxiliary data gets stored in Table1.Passou
Table1.Passou = .T. (Green)
Table1.Passou = .F. (Red)

Thank you for your help.
