TRxDbGrid with lookup field

[nelson777]

About the TRxDbGrid component from RxLib for Lazarus package (http://alexs75.narod.ru/fpc/rxfpc/index.html), does it support edditing a lookup field  in a combo-like manner ?

I only see a fixed pick-up list. Is there something like OnSelectEditor event ?

It should be realized in standard DBGrid - rxDBGrid only expands functions standard DBGrid. And in Delphi it too is realized in DBGrid. It is necessary to ask Jesus Reyes or to send it a ready code.

Sorry, I didn´t understand. OnSelectEditor event IS present on DBGrid, so it should be published by TRxDbGrid, right ? So if it isn´t, I think it was deliberately hidden by the developer of Rx package, am I right ? In this case what would Jesus Reyes do ?

I need this event, so I can implement the procedure I described in this thread

n RxDBGrid I have published those properties which is in DBGrid and was not present in RxDbGrid. It will be in following version (1.1.6) - it during development - will be in the beginning of October.

Great new Alexs! looking foward to it. Can you say if you will implement the combo functionality for lookup fields as well in rxDBGrid ?

[alexs]

in future.
For this purpose I plan to use a code from components TRxDBLookupCombo.

Great! Keep up the good work!

[nelson777]

any news about this issue ?

[alexs]

I now do not have free time. All can be seen last changes on Lazarus CCR. About your request I have not forgotten.

Ok np... when you got news, let us know

BTW could you please look on z-ordering and drawing order? This might be a Lazarus/LCL bug, but if you put a RxLookupDBComboBox on top of eg: TDBGrid, the "button" and popup will get drawn behind the grid (so user can't click the arrow and can't select). Only the "edit" area will be visible.

I think this is a LCL/widgetset bug but can you confirm please?

[alexs]

i'm try to fix this

[Almindor]

NOTE: it's probably a LCL bug, happens with other components too (eg: TDateEdit)

see new version of TRxLookupDBComboBox in Lazarus CCR

Almindor2: are u using a dblookupcompo to pickup values in a DBGrid ? if that´s the case, could you please tell me how you position it ?
