Disable some columns in table control?

Hi
How to disable some columns in table control.
For Ex: Table contains 8 columns.
In first row i want to disable first 4 columns.
in second row i want to disable last 4 columns.
In third row i want to disable first 2 and last 2 columns. How can we achieve this?
Cheers,
Venkys.

HI
Create three attribute in the node which is bound to the table as data source.
say pro1, pro2, and pro3 of type wdy_boolean.
now bind the enabled property of first four column editors to pro1, last 4 to pro2, and pro3 to first 2 and last 2.
then go to the eventhandler of the dropdown 's on select event and write the code to update the values of these attribute
according to the selected value.
here is the sample code.
DATA lo_nd TYPE REF TO if_wd_context_node.
    DATA lo_el TYPE REF TO if_wd_context_element.
        DATA lv_VAL LIKE ls_dealer1-name.
    lo_nd = wd_context->get_child_node( name = 'DEALER1').
lo_el = lo_nd->get_element( ).
    lo_el->get_attribute(
      EXPORTING
        name = `NAME`
      IMPORTING
        value = lv_VAL ).
     DATA PR1 TYPE WDY_BOOLEAN.
     DATA PR2 TYPE WDY_BOOLEAN.
     DATA PR3 TYPE WDY_BOOLEAN.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
IF LV_VAL EQ 'A'.
PR1 = ABAP_FALSE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
   ELSEIF LV_VAL EQ 'B'.
PR1 = ABAP_TRUE.
PR2 = ABAP_FALSE.
PR3 = ABAP_TRUE.
ELSEIF LV_VAL EQ 'C'.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_FALSE.
ENDIF.
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO1'
   VALUE = PR1
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO2'
   VALUE = PR2
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO3'
   VALUE = PR3

Hi,
Let your table control name in Screen painter be TC1.
READ TABLE TC1-COLS INTO WA_COLS (some wok area)
             WITH KEY SELECTED = 'X'.
        IF SY-SUBRC = 0.
          CLEAR: W_DUMMY, W_COL_NAME.
          SPLIT WA_COLS-SCREEN-NAME AT '-' INTO W_DUMMY
                                               W_COL_NAME.

Push button in one of the columns of Table Control

Hi,
I have a requirement, where i have to display a push button in one of the columns of table control for long text. When user clicks on the control, a pop up has to be appeared in which user should be able to enter some meaning ful description and save it. please suggest me how to do this requirement.
Best Regards,
Phani Kumar. S

Hai,
You can drag n drop a button to the required column in the table control and give the required parameters like ok_code , name etc.
You can now place a text field as the heading of the column.
Now when the user clicks the the button in a row, read the corresponding line in which he has clicked.For that u can use
get cursor lines wrk_line.
now u'll get the data in that row using
Read table it_tab into wa_tab index wrk_line.
now u can call the text editor (using FM's READ_TEXT ,EDIT_TEXT and CREATE_TEXT in which the user can enter the meaningful description and save it.
When u save the text entered save it with a key part of the row that was read earlier(keep it as the text name).
So now if u need to get the description which was entered earlier u can easily read the text (using READ_TEXT ).
I hope this will be helpful for u .
Thanks

Disable rows of a table control

Hi Experts,
I want to disable a row in table control, whenever SAVE is pressed.
Scenario: A Table control having 5 rows. User entered data in the first row and pressed SAVE, then
                that particular row should become greyed out or disabled, so that the user cant change or edit
                anymore.
Thanks

Hi Chandan,
in the PBO write the code to make the field display by the below logic..
first read the table control internal table line and check whether the field is filled if the field had value make it display mode else make it input filed..
see the below logic how to write it..
PROCESS BEFORE OUTPUT.
* Table control for OUTPUT
LOOP AT t_zcxref_classes INTO wa_zcxref_classes
       WITH CONTROL tc_batch .
    MODULE charac_classname_out.
ENDLOOP.
MODULE charac_classname_out OUTPUT.
* Table control reading values from input screen & displaying on screen
READ TABLE t_zcxref_classes INTO wa_zcxref_classes
                            INDEX tc_batch-current_line.
* Logic for screen Display when Required Flag = 'D'
IF wa_zcxref_classes-required_flag is not intial.      "if the input field has some value making as disaply
    LOOP AT SCREEN.
      IF screen-name = 'WA_ZCXREF_CLASSES-ATWRT'. "field to make as display
        screen-input = 0.
      ENDIF.
      MODIFY SCREEN.
    ENDLOOP.
ENDIF.
ENDMODULE.

Default value for a column in Table Control

Hi friends, can i set dinamcally a default value for a column in table control?, this column is check type. This default value must appear in empty rows,
thanks

ADD A MODULE AS Module yyyy In ur PAI.
as
In PAI.
LOOP at itab.
Module YYYY
ENDLOOP.
Module YYYY.
LOOP AT SCREEN.
    IF SCREEN-NAME = 'ITAB-VAL.
      ITAB-VAL = 'XXXXXXXX'        "(DEFAULT VALUE)
      SCREEN-INPUT = 0.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
End module.
*note
make this event work only if the previous column is filled okay.
the display will be in display mode on the screen as screen-input = 0.
see that in the table control u can get the table field for all the rows even though you are processing on some fields .
so what u do is make that particular filed masked(no i/p field and populate the field that will be better instead of populating all the columns okay.
hope this helps you out ,

JTable - Disable some columns

How should I disable some columns in a JTable so that they cannot be edited at all? The methods provided do this but double clicking the column enables it.

Hi
i dont know whether u r using TableModel or not.
if ur using a customTableModel for ur entries ..
u can implement the following method of
Table Model Interface.
public boolean isCellEditable(int rowIndex,
int columnIndex)then implement in such a way that ..
compare always with ur column number and return false.
as follows.public boolean isCellEditable(int rowIndex,
int columnIndex){
if (columnIndex ==4 )
return false;
else
return true;
}above code makes all cells in the col=4 uneditable.
even u rearrange the cols in table it works as per documentation.
test this .. and let me know whether u succeeded r not.
note: i think The implementation of this method in AbstractTableModel or defaultTableModel
returns true always.
thanks

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

How to add a column in table control

Hi ,
Can any one tell me how to add a column in table control? My requirement is to add two columns ( custom fields ) into table control ( It is a standard program). I have added the column in the table and also in the table control. But when I am running the standard program, The newly added column is not there. But I have added in the perticular screen. Change is not reflected.
Can anyone help me on this please.
Thanks in advance.
Regards,
Lakshmi.

Hi,
Ensure the following :
1. After adjusting the database, you`ll have to use the database utility and activate the table.
2. If you have changed the standard screen, in tcode se80 -- right click on the program and click activate all. This activates all objects related to that program.
Now execute the program.
Reward if helpful.

Hiding columns in table control

Hi Experts,
I have requirement to hide certain columns in table control. I have tried my best to use SCREEN structure with ACTIVE, INVISIBLE, INPUT, OUTPUT options, but not working properly.
The table control has nearly 10 columns with DATE as the first one. Once the screen appears after executing program, the second and third columns should be hidden and when double clicked on any date value from the basic list, the hidden columns should be visible with its values in the next level.
I am not able to hide columns in table control. By the way, suggest me options for double clicking in table control too.
Thanks.

Hi,
The value of sy-ucomm when user double clicks is /CS
To get the details of field name and value use:-
GET CURSOR FIELD g_cs_field VALUE g_cs_value.
Now you can code in PAI to display those two columns initially hidden by the user:-
CASE sy-ucomm.
WHEN '/CS'.
    IF g_cs_field = '<field1_name>'.
      LOOP AT SCREEN.
        IF screen-group1 = 'ABC'.
          screen-invisible = 0. "display control
          screen-active = 1.
        ENDIF.
        MODIFY SCREEN.
      ENDLOOP.
    ENDIF.
ENDCASE.
Remember that in PBO of screen you have written a code to hide these same columns initially, so make sure that the code is not executed when user double clicks to display those columns.
Try this code for hidding the columns in table control initially.
MODULE status_8001.
LOOP AT SCREEN.
    IF screen-group1 = 'ABC'.
      screen-invisible = 1. "hide control
      screen-active = 0.
    ENDIF.
    MODIFY SCREEN.
ENDLOOP.
ENDMODULE.
Hope this helps you.
