>A row in a grid needs to be validated BEFORE allowing the user to leave therow without relying on DBC rules (pre-validation is desirable with remote tables and with table buffering) We need properties we can test in

>BeforeRowColChange should have LPARAMETERS for the new row and column the user is trying to go to. These parameters should retun 0 if the user clicks outside the grid. With that information, we could trigger record validation at the grid level to prevalidate row data when we are using table bufferring.

However the LPARAMETERS only includes an index number for the COLUMN the user selects. Is it possible to determine whether or not they're trying to access a different ROW? Ultimately, is it possible to restrict access of a grid to one row at a time?
