Hi,

You can get the index on clicking of the link_to_action cell. Write the below code in onAction of link_to_action cell editor:

DATA lr_el_element TYPE REF TO if_wd_context_element.
   DATA lv_index TYPE i.
   lr_el_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
    lv_index = lr_el_element->get_index( ).

Now lv_index contains the index of clicked column.

Hope this helps u.,

Regards,

Kiran

Hi Ami,

There is actually a number of ways to do this, one is by creating an 'onSelect' event method for your table. A second method is a more generic way which allows you to add the functionality to any action/process within your webdynpro application. You could therefor have a separate button which captures which row has been selected.  (These two methods assume lead selection is being used, if lead selection is not active on your table element then you will need to use the GET_SELECTED_ELEMENTS method to retrieve the selected rows.)

From the actions tab you can double click on your button ACTION to view its associated method and add the below ABAP code to it. In the sample code below 'CARRIERS' is the context node assigned to the table.

  Data: context_node type ref to if_wd_context_node.

  Data: it_scarr type STANDARD TABLE OF if_view1=>element_CARRIERS,

        wa_scarr like line of it_scarr.

  data: ld_element   type ref to if_wd_context_element.

  context_node = wd_context->get_child_node( name = 'CARRIERS').

  ld_element   = context_node->get_lead_selection( ).

  if  not ld_element is INITIAL.

    ld_element->get_static_attributes( IMPORTING

                                        static_attributes = wa_scarr ).

  endif.

* Data of selected row is now contained in wa_scarr
