How to select all rows in ALV OO?

Question

I've created an ALV with CL_GUI_ALV_GRID using the standard PBO/PAI but when I use the method I modify the layout to include checkboxes for every row by this way:

g_layout-zebra        = 'X'.
g_layout-cwidth_opt   = 'X'.
g_layout-cwidth_opt   = 'X'.
g_layout-sel_mode     = 'D'.
gv_variant-report     = sy-repid.
gv_variant-username   = sy-uname.

enter image description here

It shows as unchecked by default, how can I select all rows? And is it possible to select more than one row clicking the checkbox?

ALV OO could be several technologies. To clarify, you are using `CL_GUI_ALV_GRID`. — Sandra Rossi, Feb 17 '22 at 16:10
Please post a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example). — Sandra Rossi, Feb 22 '22 at 15:18
Are you using `BOX_FNAME`? (it's why it's important to provide a minimal reproducible example, people can't propose a solution which solves your exact issue) — Sandra Rossi, Feb 22 '22 at 16:33

Manual way to select all rows

Click the very first button in the header row. This will select all rows.
Select the first row with the button, scroll to the very end and Shift+Click on the select button in the very last row

Use the set_selected_rows method. Like

lo_alv->set_selected_rows(
  it_row_no = VALUE #( FOR i = 1 THEN i + 1 WHILE i <= lines( lt_sflight ) ( row_id = i ) )
).

(Assuming the displayed table is lt_sflight)

Additional documentation can be found here.

I've used the code in the show_data module of PBO and it shows unselected – usr1990 Feb 21 '22 at 09:24
@usr1990 Do you have a minimal reproducible example so we can check? – peterulb Feb 22 '22 at 10:11

You can use set_selected_rows method like this.

  data: lr_selections type ref to cl_salv_selections,
        lt_rows       type salv_t_row,
        lv_count      type i.

  describe table gt_table lines lv_count.
  do lv_count times.
    append sy-index to lt_rows.
  enddo.

  lr_selections = gr_alv->get_selections( ).
  lr_selections->set_selected_rows( lt_rows ).
