Finding index of row , for which event is to be trigered.

[former_member184111]

Hi All,

We have a delete icon in one column of a tableview.

As soon as the row is selected,the icon becomes visible.Below is the code for it:

WHEN 'ACTIONS'.
      IF p_edit_mode IS NOT INITIAL.
DATA col_image TYPE REF TO cl_htmlb_image.
col_image = c l _ h t m l b _ i m a g e = > f a c t  o r y (   i d   =   p_ c e l l _ i d   s rc   =   ' . . / z _ e c a r _n e w u i / d e l e t e _ i c o n . j p g '   
 a l t   =   ' d e l e t e   r o w '   on c l ic k  =  ' d e l e t e ' ) . 
   p_ r e p l a c e m e n t _ b e e   =   c o l _ i m a g e . 
   E N D I F .

Code in OnInputProcessing:

IF event IS NOT INITIAL AND event->event_name = htmlb_events=>image .
*  tv_event ?= event .
  CASE event->event_server_name.

**Delete icon in tableview.

    WHEN 'delete'.
      DATA: cell_id_del(20).

      DATA: total_rows TYPE i.
      DATA: BEGIN OF wa_matnr,
              matnr TYPE bbp_ws_oci_item_s-matnr,
            END OF wa_matnr.
      DATA: it_matnr LIKE TABLE OF wa_matnr.

*      GET PARAMETER ID cell_id_del  FIELD cell_id_del.
      
      LOOP AT itab_row_idx INTO wa_row_idx.
        READ TABLE new_item INTO wa_item INDEX wa_row_idx-row_idx.
        wa_matnr-matnr = wa_item-matnr.
        APPEND wa_matnr TO it_matnr.
      ENDLOOP.

    


      LOOP AT it_matnr INTO wa_matnr.
        DELETE new_item WHERE matnr = wa_matnr-matnr.
      ENDLOOP.

      DESCRIBE TABLE new_item LINES total_rows.
      cl_htmlb_manager=>check_tableview_all_rows(
      rowcount = total_rows
      request = request
      id = 'mat_final'
      check = ' '
      ) .
ENDIF.

Now suppose there are 5 rows in the tableview,user selects first three rows ,so all three rows are editable now and delete icon is visible for these rows .Now if the user click delete icon of second row, how can i find out that delete icon on second row is pressed?

Thanks,

Anubhav.

IF you have a reference to the interface if_htmlb_data in the DO_HANDLE_EVENT, all the values should be in the reference.

The value would be in either of these variables.

EVENT_SERVER_NAME

EVENT_ID

Hi Amandeep,

Found the ID of row for which event is trigered in EVENT->EVENT_ID

where

event             TYPE REF TO if_htmlb_data.

Thanks a lot.

Vijay and Michale thanks to you too for the inputs.

you can use the class CL_HRRCF_ITERATOR method GET_TV_ATTR , and you can get the event and index of the row clicked. I managed with this in one of my application.

[former_member184111]

Hi Vijay,

I am developing these applications on SRM , so i guess HR related FMs are not available...let me check and get back tomorrow....

Thanks,

Anubhav.

[former_member188685]

that is not HR related...? , it is Service class for Table view iterator. if you don't find it you create a method in your controller and call it inside do_request or inputprocessing . that class in not available in 4.7, i copied the logic into a controller method, it worked well for me.

[former_member184111]

Hi Vijay,

Thanks for the information , but it is not available in the system here.where can i find the logic to copy...and i am working with Page with flow logic.

Thanks,

Anubhav.

[former_member188685]

if you can access to ECC5.0 or ECC6.0 system you can get the logic. if you are doing in Page with flow Logic then you may have to add the method in the application class. if you don't have any application class inyour application then create one , add the method specified above, use all the importing/exporting parameters and logic.

if you still don't find it , here is the code

How did you implement the delete icons? Using a table view iterator??? Maybe you can add a unique ID to each icon, so that you can get the row number from the specific icon in the oninputprocessing event (when you get the ID of the component which triggered the oninputprocess event).

[former_member184111]

Hi Michael,

Can you please elaborate on how to add a unique ID to every icon and how to read it in oninputprocessing?

A code snippet will be of great help.

Thanks,

Anubhav.
