hi

i have a table in my webdynpro screen. The employee can add rows to this table.

the new line is always added at the buttom of the table - i mean it is always added as the last row.

i want to let the user the option to add rows bwtween 2 existing rows - the user will mark the row and press the vutton "insert row" and a new row will be entered between the existing rows (like in EXCEL ). Is there a way to do that ?

Thanks

steps to do:

1. get lead selection of node by using  if_wd_context_node method get_lead_seelection_index.

2. get table using if_wd_context_node method get_static_attribute_table.

3  you can put all rows of table greater than lead_selation into another ( temporary ) internal table then append a new row in main internal table.

4. put all data from temporary internal table into main table and bind main table with node using method bind_table.

Hi,

I am sharing a code sample to get the selected rows of a table. Here we have a table with flight booking details, user can select more than one row.

Please refer the code below:

  DATA: lo_nd_bookings TYPE REF TO if_wd_context_node,
        it_selrows  TYPE wdr_context_element_set,
        wa_selrows LIKE LINE OF it_selrows.
  DATA ls_bookings TYPE wd_this->element_bookings.
  DATA lt_bookings TYPE wd_this->elements_bookings.
*   navigate from <CONTEXT> to <BOOKINGS> via lead selection
  lo_nd_bookings = wd_context->get_child_node( name = wd_this->wdctx_bookings ).

*   @TODO handle not set lead selection
  IF lo_nd_bookings IS INITIAL.
  ELSE.
    CALL METHOD lo_nd_bookings->get_selected_elements
*          EXPORTING
*            including_lead_selection = ABAP_FALSE
      RECEIVING
        set                      = it_selrows
        .
    LOOP AT it_selrows INTO wa_selrows.
      CALL METHOD wa_selrows->get_static_attributes
        IMPORTING
          static_attributes = ls_bookings.
      APPEND ls_bookings TO lt_bookings.
      CLEAR  ls_bookings.
    ENDLOOP.

  ENDIF.

Now you know the row which was selected. Get the data from the context node in the internal table, add a blank row in the internal table at the correct index and again bind the internal table to your context node.
