Check box display

[Former Member]

Hi,

I have 6 checkboxes in a screen. I am getting data from an internal table and displaying it in a screen in a loop. But the check box is not in the loop. If there are only 3 rows in the internal table then only 3 checkboxes should be displayed. How is it possible?

Pls help.

data : v_lines type i,
       v_chk(1).

describe table itab lines v_lines.

do v_lines times.
  write : v_chk as checkbox
enddo.

or u can put v_chk in ur internal table and u can write the checkbox while looping at internal table

data:begin of itab occurs 0,
       chk(1),
       field1 like...
       ......
     end of itab.
loop at itab.
  write : itab-chk as checkbox.
  *display other fields here
endloop.

Hi Sekar,

This would work only for displaying check boxes in a loop.

If you are working with screens,

then in the PBO section,

describe table itab lines v_lines.

v_no_disp_lines = 6 - v_lines.

loop at screen.

if screen-group1 = <your group name for the check boxes>.

do v_no_disp_lines times.

screen-INVISIBLE = 1.

modify screen.

clear screen.

enddo.

endif.

endloop.

Hi Ravi,

I dont want the check boxes to be displayed in a loop.. I have 6 separate check boxes in the screen.. Only the datas from the table are in a loop. Is that possible?

give the name of ur checkboxes as chk1 , chk2 ... chk3

describe table itab lines v_lines.
v_lines = 6 - v_lines.

do v_lines times.
  
<b>  concatenate chk sy-index into name1.</b>

  loop at screen.
    if screen-name = name1.
       screen-invisible = 1.
     modify screen.
    endif.
 endloop.
enddo.

Small correction to Sekhar's code,

<b>Data: v_index(1) type n.</b>

describe table itab lines v_lines.

v_lines = 6 - v_lines.

do v_lines times.

<b> v_index = sy-index.</b>

<b> concatenate <i>'chk'</i> v_index into name1.</b>

loop at screen.

if screen-name = name1.

screen-invisible = 1.

modify screen.

endif.

endloop.

enddo.

Hello Aarthi,

As I understand, U have 6 checkbox and an screen area where u display lines from the internal table. U can code in PBO for controlling the output.

Use DESCRIBE command to check the number of lines and based on that u can use

LOOP at SCREEN.

check for the checkbox name and set the screen attributes accordingly.

endloop.
