If the filter criteria is the same for the other two tables, then the above code should work in the first combo's IC.

The testing I did was with the following settings:

- For Column's (Grid) controlsource, the field that should take the value selected from the combobox. In your example, the first column would be tabmov.codimp. Also, this works with the column's Sparse property set to .T. (Default).

- For the comboboxes: (example is for first col)
Rowsourcetype = (Fields)
Rowsource = tipimp.codimp, desimp
Boundcolumn = 1
Columncount = 2
