Button at row repeater - How to identify what line button was clicked.

[furlan]

Hi,

I`m developing a WD application using ROW_REPEATER to show a list of items. For each item, I have a button to access another view to show the detail about the line where button was clicked.

My application is very similar with example showed in this link: http://help.sap.com/saphelp_nw70/helpdata/en/44/93d3bc2e8c60d6e10000000a114a6b/frameset.htm

How can I pass the ID of the line where button were clicked to detail view?

Many thanks!

Hi,

You can proceed as explained in here. In the onAction event of the Button place the following coding:

method ONACTIONONBUTTONCLICK .
  data: lr_element type ref to if_wd_context_element,
          lv_index type i.
 
  lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT'  ).
  lv_index = lr_element->get_index( ).

Now lv_index will contain the table row number in which the Button was clicked upon.

Hi Rohit,

Thanks for your suggestion, but lv_index is always 1.

I`m still having this problem.

Hi Flavio,

I tried recreating your scenario. I am displaying the information from SFLIGHT using a RowRepeater & I have a button beside each row of data. when I click up on the button am succesfully able to retrieve the buttons information using the same approach as suggested by Rohit.

METHOD onactionfetch_bookings .
  DATA: lr_element TYPE REF TO if_wd_context_element,
        lv_index TYPE i.

  lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
  lv_index = lr_element->get_index( ).
ENDMETHOD.

Hi Rohit and Uday,

You are correct. Solution provided by Rohit solved my problem.

I found the problem. When I was implementing Rohit's solution, I was replacing 'CONTEXT_ELEMENT' by own context name 'POST'.

lr_element = wdevent->get_context_element( name = 'POST' ).

instead

lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).

Thanks for your help!

See you!

I made the same initial mistake, it seems like CONTEXT_ELEMENT is indeed a default value.

Note that this approach also works when using Button controls as Cell Editors inside Table Rows.
