changing radio button selection programatically.

Posted on Jan 08, 2007 at 09:46 AM 578 Views

I have a requirement where in when user selects a file using file open dialog, the appropriate

radio button should be selected programatically based on file type. For ex. if user selects '.csv' file the

radio button 'CSV' should be selected automatically & the screen should get refreshed. Now I need to know how the screen should be repainted.

    hi ,

    Execute the code and see if this is working for u .

    parameters : fname like rlgrap-filename." memory id m01.
      DATA : filename TYPE string.
      DATA : table1 TYPE filetable,
             rc TYPE i.

PARAMETERS : R1 RADIOBUTTON GROUP RG user-command r modif id abc
DEFAULT
 'X'.
PARAMETERS : R2 RADIOBUTTON GROUP RG modif id def.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR fname.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
      EXPORTING
        default_filename = '*.*'
      CHANGING
        file_table       = table1
        rc               = rc.

    IF sy-subrc <> 0.
      MESSAGE e000(zXXX) WITH 'Error'.
    ENDIF.

    LOOP AT table1 INTO fname.

    ENDLOOP.


at selection-screen output.

IF fname cs '.CSV'.
LOOP AT SCREEN.
IF screen-group1 = 'ABC'.
r1 = 'X'.
r2 = ' '.
MODIFY SCREEN.
ENDIF.
ENDLOOP.

elseif fname cs '.DOC'.
LOOP AT SCREEN.
IF screen-group1 = 'DEF'.
 r2 = 'X'.

    make the f4 select .CSV or .DOC and the radio button is taking the position based on the input.

    Hi Gopinath ,

    You will have to get the file type , may be from the extension of the file and then use the at selection-screen output event for the same.

    here is a sample program which works when you enter file as 'CSV' or 'DOC'

    PARAMETERS : FILE(10),
             RB1 RADIOBUTTON GROUP G1 USER-COMMAND RB ,
             RB2 RADIOBUTTON GROUP G1.

AT SELECTION-SCREEN OUTPUT.

 LOOP AT SCREEN.
   IF FILE = 'CSV'.
     IF SCREEN-NAME = 'RB2'.
       SCREEN-ACTIVE =   0.
       MODIFY SCREEN.
     ENDIF.
   ELSEIF FILE = 'DOC'.
     IF SCREEN-NAME = 'RB1'.
       SCREEN-ACTIVE =   0.
       MODIFY SCREEN.
     ENDIF.
    ENDIF .

 ENDLOOP.

    This code will hide the other radio button ,

    Do fell free to revert back if you have any issues ,

    Regards

    Arun

    hi there,

    in the corresponding block for output ( AT SELECTION-SCREEN OUTPUT if there is a selection screen or within a PBO module) you just set desired radiobutton to 'X' and clear all other radiobuttons from the same radiogroup (otherwise you'll get a short dump).

    please ask if questions (but firstly give all relevant info)

    if you are using selection screen for that you have to use

    at selection-screen output.

    if p_file = 'CSV'.

    radio1 = 'X'.

    endif.

    like that.

    or if you have any your screen you have to do it in PBO.

    Hi gopinath,

    1. use the event AT SELECTION-SCREEN OUTPUT.

    2. There, just put

    if filetype = 'CSV'.

    radiocsv = 'X'.

    endif.

    regards,

    amit m.

    sorry as per as i know if you enter some value in the selection screen field and press enter it will trigger at selection-screen and then again it will trigger at selection-screen output. Correct me if i am wrong.

    hi,

    the AT SELECTION-SCREEN OUTPUT is executed everytime something happens in the screen (enter values, push buttons, etc) since is the correspondent of the PBO for normal screens.

    so, if you want to modify the screen elements (activating/deactivating, modifying input, etc) or want to modify values you must do it here.
