Help regarding Vertical Scrolling in Table Control...

Former Member · ‎2009 Apr 15

Hello experts,

Thanks for answering my previous question very quickly. Once again I came up here to clear my doubt in Table controls.

Can anyone send me a link which will explain the Table controls vertical scrolling easily and with understandable example. Iam very much confused with different answers in this forum regarding vertical scrolling.

Actually my problem is that Iam able to enable the vertical scroll bar in table control . However, If iam moving the scroll bar up and down my data is vanishing and at last empty table control is looking at my face to add some data into it.

Thanks in advance and if possible send me some video links to clear of my mind.

Hi,

What you need to do is to modify the internal table from table control whenever a user action is performed.

Follow:-

it_zekpo is my internal table w/o header line,

wa_zekpo is work area.

Name of input/output fields on screen are:-

wa_zekpo-field1,

wa_zekpo-field2, and so on...

Use code:-

At screen logic:-


PROCESS BEFORE OUTPUT.
*  MODULE status_8003.
 
  LOOP WITH CONTROL po_tab. "po_tab is table control on screen 8003
    MODULE read_data. "<--read internal table into table control
  ENDLOOP.
 
PROCESS AFTER INPUT.
*  MODULE user_command_8003.
 
  LOOP WITH CONTROL po_tab.
    MODULE modify_data. "<--modify internal table from table control
  ENDLOOP.

In PBO:-


*&---------------------------------------------------------------------*
*&      Module  READ_DATA  OUTPUT
*&---------------------------------------------------------------------*
MODULE read_data OUTPUT.
  READ TABLE it_zekpo INTO wa_zekpo INDEX po_tab-current_line. "po_tab is table control name
 
  data : line_count type i.
 
  describe it_zekpo
  lines line_count.
 
  po_tab-lines = line_count + 10.
  "to increase the number of lines in table control dynamically and enable vertical scroll bar
 
ENDMODULE.                 " READ_DATA  OUTPUT

In PAI:-


*&---------------------------------------------------------------------*
*&      Module  MODIFY_DATA  INPUT
*&---------------------------------------------------------------------*
MODULE MODIFY_DATA INPUT.
  MODIFY IT_ZEKPO FROM WA_ZEKPO INDEX po_tab-currentline.
  "this will modify the contents of existing line
ENDMODULE.                 " MODIFY_DATA  INPUT

Now when you add some records into table control and perform any user action, the records will retain.

Hope this helps you.

Regards,

Tarun

see the following example:

FORM compute_scrolling_in_tc USING p_tc_name

p_ok.

&SPWIZARD: BEGIN OF LOCAL DATA

DATA l_tc_new_top_line TYPE i.

DATA l_tc_name LIKE feld-name.

DATA l_tc_lines_name LIKE feld-name.

DATA l_tc_field_name LIKE feld-name.

FIELD-SYMBOLS <tc> TYPE cxtab_control.

FIELD-SYMBOLS <lines> TYPE i.

&SPWIZARD: END OF LOCAL DATA

ASSIGN (p_tc_name) TO <tc>.

*&SPWIZARD: get looplines of TableControl *

CONCATENATE 'G_' p_tc_name '_LINES' INTO l_tc_lines_name.

ASSIGN (l_tc_lines_name) TO <lines>.

*&SPWIZARD: is no line filled? *

IF <tc>-lines = 0.

*&SPWIZARD: yes, ... *

l_tc_new_top_line = 1.

ELSE.

*&SPWIZARD: no, ... *

CALL FUNCTION 'SCROLLING_IN_TABLE'

EXPORTING

entry_act = <tc>-top_line

entry_from = 1

entry_to = <tc>-lines

last_page_full = c_x

loops = <lines>

ok_code = p_ok

overlapping = c_x

IMPORTING

entry_new = l_tc_new_top_line

EXCEPTIONS

NO_ENTRY_OR_PAGE_ACT = 01

NO_ENTRY_TO = 02

NO_OK_CODE_OR_PAGE_GO = 03

OTHERS = 0.

ENDIF.

*&SPWIZARD: get actual tc and column *

GET CURSOR FIELD l_tc_field_name

AREA l_tc_name.

IF syst-subrc = 0.

IF l_tc_name = p_tc_name.

*&SPWIZARD: et actual column *

SET CURSOR FIELD l_tc_field_name LINE 1.

ENDIF.

*&SPWIZARD: set the new top line *

<tc>-top_line = l_tc_new_top_line.

ENDFORM. " COMPUTE_SCROLLING_IN_TC

Please go through my code and suggest me solution.

In my table control Iam displaying as well as getting data to update.

So I have written code for "Enter" like it will get data to another internal table IT_PO_CHLN when enter was pressed with changes that was done in table control and while displaying it will upload the changes compltly to table which was used in table control(IT_PO).

So, after I scroll down at IT_PO on screen and press enter my lines that come first in IT_PO are disappearing when I scroll it up again.

Just like that after few scrolls all the data in Table control is disapperaing.

Thanks Experts I resolved it myself. I used following code,I hope this may be helpful for someone in need
