WD table get Line selection

Hello all,
how can'i get the selected line in a Table UI element ( not ALV UIelement), which can methode in which class trigger this line selection? and olso the ction that cant trigger it.
Thank you all

Hi,
Up to now we are discussing about table ui element. your requirement is ALV Table.
Go to veiw->select methods->create one method say onselect, make it event handler(method type ) and in event click
f4 you get all options there you can select onleadselect select that write your code in your new method.
Cehckk this..

Table control line selection issue

HI im facing a problem in table control.
I have a table control with selection column ( single ).
First time when i select a row its is marked X in the internal table,
Now again when i select another row .. The old row still holds the value X and the new row is gettign marked as X.
The problem here is the old selection is not getting cleared in the internal table.
This is the statement used in PAI
MODIFY gt_header INDEX tbl_header-current_line FROM wa_header .
Here the previous value is not getting cleared.

KSD,
During PAI Loop, the screen flow logic loops only through the visible table control lines. In your case, the user has scrolled down and seeing line 30 to 40 (say for example) after selecting a line in first page view. This is very common with any table control.
Now user is viewing 1 to 10 lines of the TC and have selected 3rd line. User then scrolls down by pressing page-down - now PAI is triggered and the internal table's 3rd line is modified with MARK='X'. User then views lines 30 to 40 and selects 33rd line. Now table control will automatically clear the MARK in 3rd line in the Table Control only. But it is the responsibility of the developer written code to clear the same in the Internal Table.
So within PAI Table Loop, you have to check the MARK which is coming from Screen to ABAP program every-time and if it is 'X', you have to clear any other line's MARK. Remeber you should not do this for multi-select. There is an attribute of the table control LINE_SEL_MODE. The above logic of clearing other lines' MARK should be implemented only after checking this attribute.
So incidentally your solution was the appropriate one.
Cheers,
Suresh

Table control: Line selection single issue

Hi experts,
I have created a table control and in the screen painter I have defined the line selection as "Single" for table control.
The table control can display upto 20 lines in a screen and i can select a single record only which pertains to my requirement. if I try to select two records it will not allow.
Issue: consider i select a single record from the first 20 lines displayed in screen, then i scroll the records in the table control so that it displays the records from 21 to 40. if I select a single record now from line 21 to 40, the first record that i selected is not getting deselected. That is, totally two lines are getting selected.
How to overcome this issue
Thanks in advance
Regards
Anand

Ok
The "problem" is here:
Types: Begin of ty_ic,
ic(20),
desc(20),
sel(1) <--------------------------------
End of ty_ic.
You've ha a field for selected line and that field is used in table control definition as you've written:
"Note: wa_ic is the structure used in table control and wa_ic-sel is the mark field defined the table control attributes"
So you're using the structure WA_IC as header line of internal table IT_IC and also as input/put field of your table control (I mean the screen fields of table control are based on WA_IC).
You don't need any code in PBO to move the data from internal table to table control, because the headerline of IT_IC and field of table control are the same, infact you've implemented only the code in PAI to save the data from table control to IT_IC:
Loop at it_ic.
Modify it_ic from wa_ic index tc_ic-current_line
Endloop
t's a good solution if it needs to transfer all data to table control automatically: it doesn't need any code in PBO
but, of course, there'll be a problem when you don't need to display something, in this case you have to think a solution, I mean you have to write a code in order to avoid to display those data.
It's the case of the selected line: in your situation all selected lines keep the selection, because the code to clear IT_IC-SEL is missing: only the user can deselect a line, but if he doesn't do it, the line will remain selected after navigation.
So you make to be sure to clear all selected lines are not displayed.
You need to create a code in PAI out of the loop of table control where you clear the flag SEL, in order to do it you need to consider:
- The index of the first record displayed in table control is stored in field TC_IC-TOP_LINE
- The index of the last record displayed in table control can be calculated: the variable SY-LOOPC indicates how many rows can be displayed in table control, so the last record will be: TC_IC-TOP_LINE + SY-LOOPC.
So you need to clear the field SEL for all records not displayed, a code like this:
PROCESS PAI.
LOOP AT IT_IC.
 MODULE GET_LOOPC.
ENDLOOP.
MODULE CLEAR_SEL.
MODULE GET_LOOPC..
 TOT_LINE_DISPLAYED = SY-LOOPC.
ENDMODULE
MODULE CLEAR_SEL.
* Here you need to clear the selection of the records before of TOP_LINE
 IF TC_IC-TOP_LINE > 1.
 LOOP AT IT_IC INTO WA_IC TO TC_IC-TOP_LINE.
 CLEAR WA_IC-SEL.
 MODIFY IT_IC FROM WA_IC.
 ENDLOOP.
 ENDIF.
* Here you need to clear the selection of the records after the last one:
 LAST_INDEX = TOT_LINE_DISPLAYED + TC_IC-TOP_LINE.
 DESCRIBE TABLE IT_IC LINES SY-TABIX,
 IF SY-TABIX > LAST_INDEX.
 LOOP AT IT_IC INTO WA_IC FROM LAST_INDEX.
 CLEAR WA_IC-SEL.
 MODIFY IT_IC FROM WA_IC.
 ENDLOOP.
 ENDIF.
ENDMODULE.

TABLE CONTRL-LINES SELECTED

Hi All.
I have one table control and I want to find out how many line (rows) are selected .
Can any one help me how to calculate total rows of table control are selected.
Thanks in advance

HI,
If you want to find the no. of rows selected,you have to use a field of length 1 in database[say pick],and update the internal table everytime a field is selected in PAI.Kindly reward points by clicking the star on the left of reply,if it helps.

How to implement line selectability for a table control using table Wizard?

Hello SDN Community,
I have created a table control using the Table Wizard. I found my exact question in this forum, but unfortunately it had not been andsered. While I cannot paste a screen-print into this plane-text area, here are the steps I followed...
1) SE51
2) Create new screen 0100
3) Click Layout button
4) Clidk Table Control (with Wizard) and draw box on canvas.
5) Step is "Start" - click Continue
6) Step is "Name of Table Control" - provided name
7) Step is "Table Name" - provided name of dictionary table (AUFK)
8) Step is "Definition of Columns" - selected order numver and order text
9) Step is "Table Control Attributes" - Line Selectability is in display mode - cannot set it.
I would like to have a selectability column for my table. Would appreciate any insight into how to do this.
Thank you,
Dean Atteberry.

This is a puzzling...
For the table control wizard, in the Table Control Attributes step, I was able to get line selectability to open up by declaring a char01 data element at the beginning of my type.
The puzzling is in regards to the "Selection col. fld" entry field.
If I leave it blank and try to go to the next step, I get message "Enter the name of the selection column if you are using a program table"
So it looked like it wanted to know the name of my selection column. So I type in "CHAR1". and got the message "The field "CHAR1" for the selection column is already contained in the table."
Hmmmmm.... don't understand............

How to process Line Selection on ALV Table in ABAP WebDynpro

Hi there,
I have a view with an ALV table whose context node retrieves its data from a Service Call for a method.
The method provides certain data of a database table which the ALV displays.
Now I would like to be able to select one row of that ALV table and after pressing a button or doubleclicking on the row or whatever a different view (as for me it is also ok on the same view) should appear to display the details of that selection.
I only need to know how to retrieve the selected data.
Or its index within the internal table.
I am already looking for hours for a useful thread and actually there is one which obviously is about a similar issue apart from the multiple selection part:
How to process multiple row selection in ALV table in Wendynpro ABAP? Help!
but i am afraid that i don't understand it. Or at least I misunderstand it since it does not work with me.
The system example mentioned in the thread does not help me either because it somehow does not correspond to my needs, does it?
It would be GREAT if somebody could help me with that. Please keep it simple for I am not an expert in webdynpro yet (obviously ^^) and also please explain in detail what I have to do with the context nodes since I am not sure whether the selection is stored in my already existing node or whether I need a special one for that.
Thanks!!
christina

Hi Christina,
If you just want to get one column data of the line that user clicked, use the Web Dynpro Code Wizard to Read Context of attibute you needed, then you will get code as follow:
* Define data for read attribute
 node_alv TYPE REF TO if_wd_context_node,
 elem_alv TYPE REF TO if_wd_context_element,
 stru_alv TYPE if_view_display=>element_alv ,
 item_column_name LIKE stru_alv-column_name.
* navigate from <CONTEXT> to <ALV> via lead selection
node_alv = wd_context->get_child_node( name = if_view_display=>wdctx_alv ).
* get element via lead selection
elem_alv = node_alv->get_element( ).
* get single attribute
elem_alv->get_attribute(
 EXPORTING
 name = `COLUMN_NAME'
 IMPORTING
 value = item_column_name ).
The value of column_name is stored in item_column_name.
If you need the index that the user clicked, try this:
* Definition of field symbol for index
FIELD-SYMBOLS : <fs_index> TYPE data.
* Get the selected index
ASSIGN r_param->index->* TO <fs_index>.
The index of clicked line is stored in field symbol <fs_index>.
Hope it will help.
Best Regards,
Stephanie

Ajay

You only have only one option in the DDI to display in the example. when you have multiple values
i assume that by adding an empty row like this will lose the SELECTION MADE in DDI. (Correct me If i am wrong)
somehow i believe that we need to bind the DD values using SET LEAD SELECTION INDEX METHOD FOR THE DDI when they are already selected and trying to BIND.
*LO_ND_DETAILS->GET_STATIC_ATTRIBUTES_TABLE(*
 *importing TABLE = LT_DETAILS ).*
** Append an empty row to lt_details*
 *append LS_DETAILS to LT_DETAILS.*
 *LO_ND_DETAILS->BIND_TABLE(*
 *NEW_ITEMS = LT_DETAILS ).*
even though the above code will have the selected value, the SELECTIONS MADE will be initialize.
you need to bind it explicitly.
you have to create an element and bind the DDI values for adding an row as SARAVANAN said.
or i guess you can continue with you code but need to use SET LEAD to display the correct SELECTIONS MADE
loop at LT_DETAILS into LS_DETAILS.
 LV_TABIX = SY-TABIX.
 LR_ELEMENT = LO_ND_DETAILS->GET_ELEMENT( LV_TABIX ).
 WD_NODE = LR_ELEMENT->GET_CHILD_NODE( 'ACTIVITY_TYPES' ).
 WD_NODE->BIND_TABLE( NEW_ITEMS = LT_ACTIVITY_TYPES ). " data for dropdown
*" try to set the desired value in the DDI when you have multiple values using SET LEAD*
 endloop.

CL_GUI_ALV_GRID: Line selection and backend table

Dear community,
is there a way to propagate line selection of ALV GRID GUI automagically to the backend data table?
This is my scenario:
1) A table containing several records with one column 'SELECTED' for selection status
2) ALV_GRID to display the table with layout info for line selection
alv_layo-sel_mode   = 'A'.
alv_layo-box_fname = 'SELECTED'.
3) At PBO methods set_table_for_first_display and refresh_table_display are called with the table containing some records marked as 'SELECTED'.
First problem here: 'SELECTED' entries are not propagated to the ALV grid (the lines in the GUI are not marked). I know I could use set_selected_rows to force the selection, but is this really necessary?
4) Then, at PAI method check_changed_data is called (and yes, event mc_evt_modified is registered).
Second problem: Changes in selection are not propagated automagically to the underlying table. I also know I could use get_selected_rows to force this update manually, but again: is this really necessary?
Can anyone explain the behavior why sorting etc. is propagated automatically to the underlying table, but not the selection of rows? Am I missing something?
Hint: Removing box_fname = 'SELECTED' and setting the fieldcatalog to display the column 'SELECTED' as editable checkbox works also. But our users are familiar with the rowmark, so this is no option.
Any suggestions are welcome.

Hello Torsten
I may be wrong but I think the field LVC_S_LAYO-BOX_FNAME is a relict from the stone-age SLIS-based ALV programming.
Using modern OO-based ALV we do not need any kind of "MARK" row but we have the appropriate methods available.

Uwe

Table Controls: - Find selected line index

HI,
I have a table control . In tis 4 lines are visible at a time..1 field in this table comntrol is a button.
when the user clicks on a button, the details of the corresponding line should be used to trigger a new screen. If the no of lines in the table control is less than 4( o of visible lines) , i can use get cursor line, to get the index of the line selected. . but if i scrolled down and selected the button in the 15 th line, then get cursor line cannot be used as it will retrieve the no 3. CAn u please give me a solution.
thnx.

declare two variables to get line count and line index
data: wrk_linecnt(10),
wrk_lineindx(10).
get cursor line wrk_linecnt.
wrk_lineindx = <table control name>-top_line + wrk_linecnt - 1.
read table <internal table used in table control> index wrk_lineindx.

Getting the selected index of a table (CL_WD_TABLE) without lead-selection

Hi
When I click in a table-UI (not alv-table) on a f4-help, I can search with se11-searchhelp on a field. After I choose something, I should also fill some other fields in the same row.
In the table I have no lead-selection. So, I am searching for a method that gets me the selected index. The element-class for the table-UI is CL_WD_TABLE.
Once I have the selected index, I could change the fields in the same row inside the WDDOMODIFYVIEW.
With activated node-selection it can be, that the user selects one row, but he starts the f4-help on another row (the lead-selection doesn't change).
I have seen this article, but i hope that for the table-UI it is different than with alv:
[ON_CELL_ACTION triggered only by ENTER ?]

Hi Lorenzo,
I'm trying to do the same thing and came up with this solution. In WDDOMODIFYVIEW, since we cannot know in which table row the user clicked the search help, I simply loop through all the rows of the table. For each row, I delegate to a method in the Component Controller which sets the specified index as the table's lead selection then reads the selected table row from the context. I can then populate fields in the selected row as needed.
METHOD wddomodifyview .
   DATA lo_componentcontroller TYPE REF TO ig_componentcontroller.
   DATA lo_nd_items TYPE REF TO if_wd_context_node.
   DATA lt_items TYPE wd_this->elements_items.
* -- Upon return from the search help, populate table row details
   lo_componentcontroller = wd_this->get_componentcontroller_ctr( ).
   lo_nd_items = wd_context->get_child_node( name = wd_this->wdctx_items ).
   lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
* Since we cannot know in which table row the user requested the search help,
* loop through all table rows, populating table row details as needed.
   DESCRIBE TABLE lt_items LINES sy-tfill.
   DO sy-tfill TIMES.
*   Delegate to the Component Controller
     lo_componentcontroller->get_table_row_detail( sy-index ).
   ENDDO.
ENDMETHOD.

At line Selection & get cursor field

Hi friends,
Could any one of u please explain about at line selection and GET CURSOR FIELD ( GET CURSOR FIELD FNAM VALUE FVAL) with sample program.
Jai.

Hello,
AT - Events in lists
Variants:
1. AT LINE-SELECTION.
2. AT USER-COMMAND.
3. AT PFn.
Variant 1
AT LINE-SELECTION.
Effect
Event in interactive reporting
This event is processed whenever the user chooses a valid line in the list (i.e. a line generated by statements such as WRITE,ULINE, or SKIP) with the cursor and presses the function key which has the function PICK in the interface definition. This should normally be the function key F2, because it has the same effect as double-clicking the mouse, or clicking once in the case of a hotspot.
The processing for the event AT LINE-SELECTION usually generates further list output (the details list) which completely covers the current list display. If you want the current list display to remain visible (to aid user orientation), you can do this with the key word WINDOW.
In most cases, the information from the selected line is used to retrieve more comprehensive information by direct reading. When displaying the original list, you store the key terms needed for this in the HIDE area of the output line.
Note
You can choose a line and start new processing even in the details lists.
The following system fields are useful for orientation purposes, since their values change with each interactive event executed.
SY-LSIND
Index of list created by current event (basic list = 0, 1st details list = 1, ...)
SY-PFKEY
Status of displayed list (SET PF-STATUS)
SY-LISEL
Contents of selected line
SY-LILLI
Absolute number of this line in the displayed list
SY-LISTI
Index of this list - usually SY-LSIND - 1 (READ LINE)
SY-CUROW
Last cursor position: Line in window
SY-CUCOL
Last cursor position: Column in window (GET CURSOR)
SY-CPAGE
1st displayed page of displayed list
SY-STARO
1st displayed line of this page of displayed list
SY-STACO
1st displayed column of displayed list (SCROLL LIST)
The system field SY-LSIND defines the line selection level (basic list: SY-LSIND = 0).
System field for interactive reporting are also contained in the System Fields for Lists documentation.
Example
DATA TEXT(20).
START-OF-SELECTION.
PERFORM WRITE_AND_HIDE USING SPACE SPACE.
AT LINE-SELECTION.
CASE TEXT.
 WHEN 'List index'.
 PERFORM WRITE_AND_HIDE USING 'X' SPACE.
 WHEN 'User command'.
 PERFORM WRITE_AND_HIDE USING SPACE 'X'.
 WHEN OTHERS.
 SUBTRACT 2 FROM SY-LSIND.
 PERFORM WRITE_AND_HIDE USING SPACE SPACE.
ENDCASE.
CLEAR TEXT.
FORM WRITE_AND_HIDE USING P_FLAG_LSIND P_FLAG_UCOMM.
WRITE / 'SY-LSIND:'.
PERFORM WRITE_WITH_COLOR USING SY-LSIND P_FLAG_LSIND.
TEXT = 'List index'.
HIDE TEXT.
WRITE / 'SY-UCOMM:'.
PERFORM WRITE_WITH_COLOR USING SY-UCOMM P_FLAG_UCOMM.
TEXT = 'User command'.
HIDE TEXT.
IF SY-LSIND > 0.
 WRITE / 'PICK here to go back one list level'.
ENDIF.
ENDFORM.
FORM WRITE_WITH_COLOR USING P_VALUE
 P_FLAG_POSITIVE.
IF P_FLAG_POSITIVE = SPACE.
 WRITE P_VALUE COLOR COL_NORMAL.
ELSE.
 WRITE P_VALUE COLOR COL_POSITIVE.
ENDIF.
ENDFORM.
Depending on whether you choose the line at SY-LSIND or SY-UCOMM, the next details list contains the corresponding value with the color "positive". If the line is chosen without HIDE information, the list level is reduced.
Variant 2
AT USER-COMMAND.
Effect
Event in interactive reporting
This event is executed whenever the user presses a function key in the list or makes an entry in the command field.
Some functions are executed directly by the system and thus cannot be processed by programs. These include:
PICK
See variant AT LINE-SELECTION
PFn
See variant AT PFn
System command
System command
PRI
Print
BACK
Back
RW
Cancel
P...
Scroll function (e.g.: P+ , P- , PP+3, PS-- etc.)
Instead of this functions, you can use the SCROLL statement in programs.
Since many of these system functions begin with "P", you should avoid using this letter to start your own function codes.
Otherwise, the effect is as for AT LINE-SELECTION; also, the current function code is stored in the system field SY-UCOMM.
Example
DATA: NUMBER1 TYPE I VALUE 20,
 NUMBER2 TYPE I VALUE 5,
 RESULT TYPE I.
START-OF-SELECTION.
WRITE: / NUMBER1, '?', NUMBER2.
AT USER-COMMAND.
CASE SY-UCOMM.
 WHEN 'ADD'.
 RESULT = NUMBER1 + NUMBER2.
 WHEN 'SUBT'.
 RESULT = NUMBER1 - NUMBER2.
 WHEN 'MULT'.
 RESULT = NUMBER1 * NUMBER2.
 WHEN 'DIVI'.
 RESULT = NUMBER1 / NUMBER2.
 WHEN OTHERS.
 WRITE 'Unknown function code'.
 EXIT.
ENDCASE.
WRITE: / 'Result:', RESULT.
After entry of a function code, the appropriate processing is performed under the event AT USER-COMMAND and the result is displayed in the details list.
Variant 3
AT PFn.
Effect
Event in interactive reporting
Here, n stands for a numeric value between 0 and 99.
This event is executed whenever the user presses a function key that contains the function code PFn in the interface definition. The default status for lists contains some of these functions.
Otherwise, the effect is as for the variant AT LINE-SELECTION. The cursor can be on any line.
Notes
To ensure that the chosen function is executed only for valid lines, you can check the current HIDE information.
This variant should be used only for test or prototyping purposes, since the default status is not normally used. Instead, you should set a program-specific status with SET PF-STATUS. This should not contain any function codes beginning with "PF".
Example
DATA NUMBER LIKE SY-INDEX.
START-OF-SELECTION.
DO 9 TIMES.
 WRITE: / 'Row', (2) SY-INDEX.
 NUMBER = SY-INDEX.
 HIDE NUMBER.
ENDDO.
AT PF8.
CHECK NOT NUMBER IS INITIAL.
WRITE: / 'Cursor was in row', (2) NUMBER.
CLEAR NUMBER.

User Action on Detail Lists
GET
Basic form 2 GET CURSOR. ...
Variants:
1. GET CURSOR FIELD f.
2. GET CURSOR LINE line.
Variant 1
GET CURSOR FIELD f.
Additions:
1. ... OFFSET off
2. ... LINE line
3. ... VALUE g
4. ... LENGTH len
5. ... AREA
Effect
Transfers the name of the field at the cursor position to the field f.
The return code is set as follows:
SY-SUBRC = 0:
Cursor was positioned on a field.
SY-SUBRC = 4:
Cursor was not positioned on a field.
Note
Unlike screen processing, list processing allows you to output literals, field symbols, parameters and local variables of subroutines. Literals, local variables and VALUE parameters of subroutines are treated like fields without names (field name SPACE, return value 0).
Otherwise, GET CURSOR FIELD returns only names of global fields, regardless of whether they are addressed directly (i.e. by "WRITE"), by field symbols or by reference parameters.
Example
DATA: CURSORFIELD(20),
 GLOB_FIELD(20) VALUE 'global field',
 REF_PARAMETER(30) VALUE 'parameter by reference',
 VAL_PARAMETER(30) VALUE 'parameter by value',
 FIELD_SYMBOL(20) VALUE 'field symbol'.
FIELD-SYMBOLS: <F> TYPE ANY.
PERFORM WRITE_LIST USING REF_PARAMETER VAL_PARAMETER.
ASSIGN GLOB_FIELD TO <F>.
AT LINE-SELECTION.
GET CURSOR FIELD CURSORFIELD.
WRITE: / CURSORFIELD, SY-SUBRC.
FORM WRITE_LIST USING RP VALUE(VP).
DATA: LOK_FIELD(20) VALUE 'local field'.
ASSIGN FIELD_SYMBOL TO <F>.
WRITE: / GLOB_FIELD, / LOC_FIELD,
 / RP, / VP,
 / 'literal', / FIELD_SYMBOL.
ENDFORM.
When you double-click the word " global field", CURSORFIELD contains the field name GLOB_FIELD, on "parameter by reference" the field name REF_PARAMETER, on " field symbol" the field name FIELD_SYMBOL, and on "local field", "parameter by value" and "literal" the value SPACE.
Addition 1
... OFFSET off
Effect
Copies the position of the cursor within the field to the field off (1st column = 0).
If the cursor is not somewhere within a field (SY-SUBRC = 4), the offset value is set to 0.
Addition 2
... LINE line
Effect
With step loops, lin contains the number of the loop line where the cursor stands. In list processing, this is the absolute line number (as stored in the system field SY-LILLI).
Addition 3
... VALUE g
Effect
g contains the value of the field where the cursor stands, always in output format (character display).
Addition 4
... LENGTH len
Effect
len contains the output length of the field where the cursor stands.
Addition 5
... AREA a
Effect
If the cursor is positioned on the field of a table view control, the name of the control is placed in the field a.
Variant 2
GET CURSOR LINE line.
Additions:
1. ... OFFSET off
2. ... VALUE g
3. ... LENGTH len
Effect
As for variant 1 with addition LINE, except that there are differences with the return code and the effect of the additions.
The return code is set as follows:
SY-SUBRC = 0:
The cursor is on one of the list lines (list processing) or on a loop line (step loop).
SY-SUBRC = 4:
The cursor is not on one of the list or loop lines.
Addition 1
... OFFSET off
Effect
Applies to list processing only. The field off contains the position of the cursor relative to the beginning of the list line (1st column = 0). With horizontally shifted lists, the offset value can thus be greater than 0, even if the cursor is positioned on the extreme left of the window.
Addition 2
... VALUE g
Effect
List processing only. The field g contains the list line where the cursor is positioned.
Addition 3
... LENGTH len
Effect
List processing only. len contains the length of the line (LINE-SIZE).

How to get the selected rows & columns in the table?

hi everybody,
In my application the table is kept inside the event structure.I select the cells in the table (using mouse) on running time.How to get the selected number of rows & columns in that table?

Hello,
You can fill selected values of the table by writing to it or the corresponding property using a property node - the table is just a 2D array of strings. I think for your "disable" question you are referring to the shortcut menu (when you right click). If you are using LabVIEW 8.x, you can edit or disable that shortcut menu - just right click on your table at edit time and choose Advanced >> Run-Time Shortcut Menu.

How do I execute some code when a line of a table control is selected?

Hi,
I would like to execute some code when a line of a table control is selected. At the moment I have to select one or multiple rows and then press enter, this forces a screen refresh and my code is executed but I would like the code to be executed as soon as any line is selected.
I've done something like this using ALV grids and object orientated code but is there a way of doing this in a normal non-OO table control?
Thanks in advance.
Gill

Hi,
U need to declare a char1 field for marking (mark field). This will reflect with value 'X' in your tcontrol internal table for all the selected rows.
Now u need to handle the okcode for enter in your PAI.
There u need to loop through the table for all marked fields.
There after u can do what ever u want.
