Thank you, Vladimir!
I have some cold and must be really sick, because I still can't do it. You must forgive me for my ignorance, but I have created a simple form with 2 grids (parent and child) and open my database (DATA.dbc) and 2 tables APP.dbf and WORKHIST.dbf.
If I rightclick on grid I get popup menu and from this point there is no place for child order only on last tab you can set key field in parent table and key field in child.
If I look in properties for grid, all I can find is Child Order and Relational Expression.
PLease, be more specific on how to set different order from relational expression.
You maybe using different grid builder, my doesn't have Child Order option ?
Thank you very much .......
