This usually depends on how you have defined your datafields.
And this can also depend on your ColumnAttributes settings.

In help, go to TIBQuery.ColumnAttributes.
There is a quite a lot of information in that section.
To centralize your settings, consider putting your global ColumnAttributes in TIB_Connection

Subject: [IBO] Checkbox in IB_Grid


Hi folks,

I have a IB_Grid that show some fields, and one of them is set as boolean at tib_query, so a checkbox appears in that collumm.

As far as I seen, the checkbox values cycle like this: F-> null -> T -> F -> ... I'd like to know if is it possible to cycle just T and F, cause null is not interesting in boolean fields right?

Any idea?
