table control: after scroll, 'single select' is not enforced

Hi guys,

4.0B: I have a big table control that the user will need to scroll.

The table control allows only single line selection, however, when you scroll

the selected line off-screen (e.g. by using the mouse scroll button or the scrollbar), the line remains selected even when you select a new one.

I haven't been able to try this behaviour out yet in a newer release.

Does anyone know a fix for this? (btw - scrolling using the scrollbar does not trigger an ok_code)

Thanks in advance.

I have currently implemented a 'quick fix':

- in PBO, compare current TC-top_line with previously saved TC-top_line

- if scrolling is detected, all selection fields are deleted

This is a coarse hack, but I don't have the inspiration to improve this, currently.

Does any of you guys have a better idea?

Thanks,

Rob

Nevermind, I found a way.

For my own reference I'll give the code.


PROCESS AFTER INPUT.                              
  MODULE exit_command AT EXIT-COMMAND.            
  LOOP AT gt_assort.                              
    FIELD gs_assort-sel MODULE tc_mark ON REQUEST.
    MODULE tc_assort_pai.                         
  ENDLOOP.                                        
  MODULE user_command_0100.

and the module:


MODULE tc_mark INPUT.                                                
  DATA: ls_assort LIKE gs_assort.                                    
  CLEAR ls_assort.                                                   
  IF tc_assort-line_sel_mode = 1 AND                                 
     gs_assort-sel = 'X'.                                            
** clear SEL in whole TC                                             
    MODIFY gt_assort FROM ls_assort TRANSPORTING sel WHERE sel = 'X'.
** set SEL in current line                                           
    MODIFY gt_assort FROM gs_assort INDEX tc_assort-current_line     
      TRANSPORTING sel.                                              
  ENDIF.                                                             
ENDMODULE.                             " TC_MARK  INPUT

Cheers,
