Get column index

[RicardoRomero_1]

Hi all,

I have a table with several columns, in each column i have the same action for the event onEnter.

I want to know the index of the column that has triggered the event.

I've debugged the method and I think the attribute that has the index is _PERS_INDEX of class cl_wd_table_column. But this attribute is protected and I couldn't find a public method for retrieve it.

Do you know how can I get this index?

I've tried to use a local class that inherit from the class CL_WD_TABLE_COLUMN for get the protected attribute. I've created a public method for get the index but by the moment doesn't work, there is a casting error:

During a 'CAST' operation ('?=' oder 'MOVE ? TO')a type conflict occurred. The source type '\CLASS=CL_WD_TABLE_COLUMN' is not compatible for assigning with the target type '\FUNCTION-POOL=ZTEST_FG
\CLASS=LCL_COLUMN

This is my code:

Method onEnter
DATA: lo_ui_elem TYPE REF TO cl_wd_input_field,         lo_ui_col  TYPE REF TO cl_wd_table_column,         lo_ui_table TYPE REF TO cl_wd_table.   DATA: lv_index TYPE i.      lo_ui_elem ?= wd_this->main_view->get_element( id ).   lo_ui_col ?= lo_ui_elem->get__parent( ).   CALL FUNCTION 'ZGET_COLUMN_INDEX'     EXPORTING       io_column       = lo_ui_col    IMPORTING      EV_INDEX        = lv_index.

FM ZGET_COLUMN_INDEX

FUNCTION ZGET_COLUMN_INDEX. *"---------------------------------------------------------------------- *"*"Interfase local *"  IMPORTING *"     REFERENCE(IO_COLUMN) TYPE REF TO  CL_WD_TABLE_COLUMN *"  EXPORTING *"     REFERENCE(EV_INDEX) TYPE  I *"----------------------------------------------------------------------   DATA: lo_column TYPE REF TO lcl_column,         lo_cast_error TYPE REF TO cx_sy_move_cast_error,         lv_text TYPE string,         lv_longtext TYPE string.   TRY.     lo_column ?= io_column.   "Here is the casting error     CATCH cx_sy_move_cast_error INTO lo_cast_error.           lv_text = lo_cast_error->IF_MESSAGE~GET_TEXT( ).           lv_longtext = lo_cast_error->IF_MESSAGE~GET_LONGTEXT( ).   ENDTRY.   ev_index = lo_column->get_index( ). ENDFUNCTION.

Local class in TOP include
CLASS lcl_column DEFINITION INHERITING FROM CL_WD_TABLE_COLUMN.   PUBLIC SECTION.     METHODS: get_index RETURNING VALUE(index) TYPE i. ENDCLASS. CLASS lcl_column IMPLEMENTATION. METHOD get_index.    index = _pers_index. ENDMETHOD. ENDCLASS.

Do you know how to do it? or what i'm doing wrong in my code?

I think you can look at the attribute, parameters in wdevents which will have the id /context element from which you should be able to find

thanks

Hi Chinna and Erhan, thanks for your answers.

I've already checked the attributes id and context element but I couldn't find a proper way to get the column index.

EDIT: I think I have the way to obtain it, I can use the method get_columns of the table UI and check each one by the ID of the column.

Ricardo,

1. Get the TableUI Element reference, CL_WD_TABLE

2. Call the method GET_COLUMN which returns CL_WD_TABLE_COLUMN ---           <lr_selected_column>

3. Call the method  GET_COLUMNS which returns table of CL_WD_TABLE_COLUMN

4.

     Loop at <table_columns> into <ls_table_column>.

          if <ls_table_column> eq <lr_selected_column>.

               lv_index = sy-tabix.

               exit.

          endif.

     endloop.

Hope this may help you.

Hi Chengalarayulu,

Thanks, I've just thought the same solution.

Hi,

You can get column name. Does that fulfill your requirement?    

[RicardoRomero_1]

Nop, I need the index because the user can change the order of the columns in run time, but I can get this index with the way explained above by Chengalarayulu. Thanks !

I dont have access now but you can try to pass ui params in method. While creating event you can set it by a checkbox.
