dynamically disabling a text field in dialogue programming

[Former Member]

Hi all ,

i am doing a case study on library management . I made a screen for editing the book details.. The initial screen will display the all the information regarding a book based on ISBN no. In top i have a change button. <b>My need is to disable only the ISBN text field when i press change button</b> .

Now i am using this code ..But this code will activate all text field.

IF OK_CODE EQ 'CHANGE'.

• Make all the Fields non-Editable

LOOP AT SCREEN.

SCREEN-INPUT = 1.

MODIFY SCREEN.

CLEAR OK_CODE.

ENDLOOP.

ENDIF

Please give a solution regarding this issue...

Hi Umesh,

U r correct but modify the codesw as follows:

IF OK_CODE EQ 'CHANGE'.
* Make all the Fields non-Editable
LOOP AT SCREEN.
IF SCREEN-NAME = 'URSCR_FLD'.
SCREEN-INPUT = 1.
MODIFY SCREEN.
ENDIF.
CLEAR OK_CODE.
ENDLOOP.
ENDIF

Hi Umesh,

Go to the Screen Painter and Double click on the Text field you are discussing here. It will open a window. In that window u will see group boxes (they are 4). For that text button sepcify group as GRP1 in any of the box. Then write foolwing code.

LOOP AT SCREEN.

IF SCREEN-GROUP = 'GRP1'.

SCREEN-INPUT = 0.

MODIFY SCREEN.

ENDIF.

CLEAR OK_CODE.

ENDLOOP.
