Hello everyone,
I would like to limit the input in a cell (column) of an rdbgrid to only the values present in its picklist, without the user being able to modify the cell with the keyboard. Is there a way to achieve this?
Thanks
Giuseppe

HI Giuseppe,
procedure TrDBGrid2.gr2KeyPress(Sender: TObject; var Key: Char);
begin
if gr2.SelectedField=SomeField then
Key:=#0;
I hope it helps
there are 2 possible solutions.
1/ use lookup field with list of values (key field and value field can have same values) and then only values from the list can be selected
2/ use OnKeyPress event and block editing for the field with picklist
begin
if gr2.SelectedField=SomeField then
Key:=#0;
end;
I hope it helps
Tomas
