Former Member — Wed, 24 Dec 2008 11:24:54 GMT

Hii All,

I have a database table where i will save the Text entered by the user.

i need to give the option of the change of text so i am using a table control and getting the Text from the table and using it and displaying the text.

The problem is when i am going for the change iam unable to see the first line in the text.

Say if i have 3 lines of text : say it is like this

1) This

2) is

3) the text.

i am unable to see the first line "This" at the first shot. it is displayed like this

2) is

3) the text.

but if i scroll down and come back to the first line i can see the first line as shown below.

1) This

2) is

3) the text.

What could be the problem?

I am using internal table with header line.

Please help me.

Thanks,

Ravindra.

If the user just enterederd the text then it would be best you use a text editor instead of going for table control ,it look good and user friendly from user point of view and it easy to create it and use the below code.

DATA: init,

container TYPE REF TO cl_gui_custom_container,

editor TYPE REF TO cl_gui_textedit.

DATA: event_tab TYPE cntl_simple_events,

event TYPE cntl_simple_event.

DATA: line(3000) TYPE c,

text_tab LIKE STANDARD TABLE OF line.

IF init IS INITIAL.

init = 'X'.

CREATE OBJECT: container EXPORTING container_name = 'TEXTEDIT',

editor EXPORTING parent = container.

event-appl_event = 'X'. "application event

APPEND event TO event_tab.

CALL METHOD: editor->set_registered_events

EXPORTING events = event_tab.

ENDIF.

CALL METHOD editor->get_text_as_stream

IMPORTING

PERFORM save_text TABLES text_tab

DATA : lt_lines TYPE STANDARD TABLE OF tline,

wl_lines TYPE tline.

DATA : wa_head TYPE thead ,

wa_tab TYPE line.

data : vl_newline(1),

data : wa_split type txt,

read table p_tab into wa_tab index 1.

CALL FUNCTION 'COMMIT_TEXT'

savemode_direct = 'X'.

COMMIT WORK AND WAIT.

ENDIF.

ENDFORM. " save_text

And on the screen define a custom control with name TEXTEDIT .

Hope this help you .

Get back to me if you have any issue with the code.

Hi ,

I cant go for any other editor Because i have to display the text box dynamically.

here by using the Table control i am changing the length and no of lines of the text box based on the values from a table.

So please help me out using this table control only.

Thanks

How you are splitting the data into itab and how you are passing it to the table control on the screen.

try in PBO.

describe table itab lines tc-lines.

also how many rows are visible in table control?? at first

are you increasing them dinamically??

please refer to the Program RSDEMO02 for further info.

Hi,

Here is my code in screen.

LOOP AT I_fobpr into w_fobpr WITH CONTROL I_TCONTROL CURSOR

I_TCONTROL-CURRENT_LINE.

MODULE display_fobpr.

ENDLOOP.

and this module display_fobpr is as follows

Module display_fobpr output.

if i_fobpr[] is initial.

select single zzimprint_chars

zzimprint_lines

into (v_imprint_chars , v_imprint_lines)

from mara

where matnr = vbap-matnr.

if t180-trtyp = 'V' AND I_FOBPR[] IS INITIAL.

perform sub_get_zztext.

ENDIF.

*----Modify the table controls length and no of lines

loop at I_TCONTROL-cols into w_cols1.

if screen-name = 'I_FOBPR-ZZTEXT'.

w_cols1-vislength = v_imprint_chars. " No of characters " this gives the dynamic length

modify I_TCONTROL-cols from w_cols1.

modify screen.

endif.

endloop.

I_TCONTROL-lines = v_imprint_lines. " This give the dynamic No of lines

zhdi_fobpr-zztext = i_fobpr-zztext.

endmodule.

in perform perform sub_get_zztext. i am selecting the data from the table if the internal table i_fobpr is initial.

So everything is working fine except that i am unable to see the first line for the first time and if i scroll down and go up i can see it.

Thanks

Ravindra.
