Hello Fred,
The goal is not to change tdropdownlisteditlb.value but to get ( nRow, nCol , value) of the selected item.
Thank you, Med

I will jump into your sample_lookup.zip asap (I am super busy this week :-( )

Hello Med.
Yes, I understood this but the fact is that I dont see how to get the column selected.
And maybe the code of tdropdownlisteditlb not permit it like it is now.

Hello fred,
You can notice that we can have any column, but the problem is the row number selected ?
for example:
var nCol:integer;
....
nCol:=1;
procedure tmainfo.onchange ()
var nRow:integer;
begin
nrow:=?????? <----------- REWARD
showmessage(lookuplb.textvalue[nCol, nRow]);
end;
Regards
Med.

Hello Fred,
Ultimately it's simplier than we thought .
Just:
ncol:=1; for example
procedure tmainfo.changeEV(const sender: TObject);
var s:string;
begin
with tdropdownlisteditlb1 do
s:=(lookuplb.textvalue[ncol,dropdown.itemindex]);
// and we can do here a dataset find ( s);
end;
Regards.
Med
PS:itemidex is in msedataedits.pas

Hello Med. Ha, ok, nice you found the solution. Huh, may I ask you to update the sample_lookup.zip file and include the missing main.mfm file? (So I can better understand what was the question and the solution). Thanks. Fre;D |

Ok, but the solution how to get the selected column if number of columns > 1 is still mystery. But that is a other story and maybe not really needed ( if you decide before popup what column must be retrieved ). |

Hello Fred,
Here is the the complete demo prj. Notice that we can use the same datasource for the lookupbuffer and the grid.
See also lookup dboptions which is important in case of adding record to dataset.

Are you talking about the GitHub site? (I dont use that feature, I prefer use git push --all.) |

Re-hello Med. You can create a directory with button [Add file] [Create new file]
In edit "Name your file..." just add a directory like test/mytest.txt |

Hi All,
I am working with tdropdownlistEditLB combined with tdblookupbuffer and I did not find the object propertie where the index and the array of data items are stored when the event onChange is fired.
There is not a dropdown.cols[n].value or a function to get ( n, value). Has anyone worked on this before to help us is this subject?
Med.
Ps: I noticed that onFilter event gives paramerters to get index and value ?
procedure tmainfo.onFilterEV(const sender: tcustomlookupbuffer, const physindex: Integer; var valid: Boolean);
and I want to do: tmsesqlQuery( datasource.dataset).indexlocal(0). find( value of column (n) index physindex.)
