Using a loop is the only way I know.
You can also update the array by using the DataGrid API, with the
SetDataOfIndex (or SetDataOfLine).
It is equivalent to your loop excepted that you have not to refresh
the whole data, only the data required by the column.
It means that by using the SetDataOfIndex, set the dgData of the DG is
not required.
Note that in this line
put the dgData["false"] of grp "DataGrid 1" into tArray
the dgData properties not accepts a parameter. Only dgText do.

The dgColumnAlignment is only provided to change the alignment of a
standard column (text and not managed by a custom behavior)
To "center" a checkbox, you have to manage it in the LayoutControl
event of the column behavior.
on LayoutControl pControlRect
centerMyCheckBox -- center the checkbox in the rect (pControlRect)
of the cell
end LayoutControl
So no need to switch to a DG form ;)
