Jorge,
The grid is a "forceful" control, it is going to
select (this.RecordSource) behind the scenes while it has focus. If the report is using a different alias then you are in trouble in the report. Other bound controls like textbox don't force the currently selected alias while they have focus.
>Could you expand on this, I'm pretty sure I print reports from forms with grids all the time, usually by clicking a button, I suppose the grid looses focus then?.
