unexpected OnKillFocus event inside grid

the attached files are slightly modified versions of sample files
i've switched on OnKillFocus event and  added
(defun c:Grid_Dcl-1_grid1_OnKillFocus (/) (princ "OnKillFocus ") (princ))
OnKillFocus triggers whenever you try to edit grid cells with "drop-down capability" (type 18, 36, 37...), in this example rows 4-5-6-7

I didn't look at your code, but I would expect the grid control to lose focus when the dropdown control gains focus.

dropdown (or combo strings) control being a cell is a part of a grid.
why should the grid lose focus then?

ps the code attached to the first post is not mine it's a sample from opendcl package.

Hi, VovKa,

the grid looses the control because any control that is shown when a cell is going to be edited is an other control but not the grid itself.

You can embed the code which shall be executed in the KillFocus event from the GridEditState. Just catch the OnStartCellEdit event and set a variable to T (for example) and set it to nil during OnEndCellEdit. Within OnKillFocus you can ask the state of the variable. That's all.

i just thought it was a bug

thank you Fred
