Hello Frederico.

I´m using a combo with a grid but when I up or down a line the text of the combo isn´t displayed, I don´t want use RowSourceType = 6 because I don´t want to show all data from my table.

Are you saying that when the combo has focus, the displayValue is blank? If this is the case, then use a RowSourceType = 3-SQl to get rid of the problem.
