Add row to ALV grid highlighting mandatory fields

Question

hello experts,
I am using grid object of cl_gui_alv_grid to display output table. Rows can be added to grid using Insert Row button of ALV toolbar (No custom button added here). The requirement is to highlight the mandatory input cells either with border or display them in different color.
This needs to be done immediatly after pressing the Insert row button, but before the row is displayed on the screen as ready for input ( NOT as a part of data validation on save or enter button).
I tried following method:
- I SET HANDLER event_receiver->handle_user_command FOR obj_grid.
- I am handling EVENT before_user_command OF cl_gui_alv_grid
- I thought of modifying CELLTAB of inserted row in this event to set display properties of required entry fields
However, the problem I am facing here is, Insert_Row button directly populates a row on display screen without triggering before_user_command event.
Is there any way I can highlight the cells of inserted row when it's populated on screen?

Hi,
Indeed this event is not triggered for some standard function. Anyhow you could do some trick:
- hide standard insert row button
- add custom button with same icon on in
- then once you press it, you will be able to hanlde it in before_user_commnad event
If you want to stick to standard solution. maybe there is some flag which must be set with some SET.. or REGISTER... method. Unfortunatelly I am not aware of such switch.
