set_selected_rows problem, nothing is selected

[Former Member]

Hi everybody,

I am facing a problem with an ALV and I am not able to solve. I have been looking the threads that already exist but I can not find the solution.

I am going to try to explain what is the problem:

There is an screen with some alv with tables related between them, whenever I double click in the first alv table the next table must be filled with the entries related and the entry that I double click it should be marked. The problem is any time I double click and the next alv table is open the one where I double click lost the line, I mean the focus goes to the first line of the table, meaning that the refreshing eliminates the actual selected entry.

This is what I tried to do but I don't know why it doesn't work.

1.- The lines selected are saved in a table.

CALL METHOD mo_alv_grid_edit->get_selected_rows

IMPORTING

et_index_rows = gi_index_rows.

2.- Refresh the alv table.

CALL METHOD mo_alv_grid_edit->refresh_table_display

EXPORTING

i_soft_refresh = 'X'.

3.- Set the lines I have before

CALL METHOD mo_alv_grid_edit->set_selected_rows

EXPORTING

it_index_rows = gi_index_rows .

Thanks very much

As per my understaning you have to use Get_selected_rows rather than set selected rows method.

Hi Pavan,

the problem is that I lost the entries that were marked, that is the reason that befores refreshing the alv, I take from the object the lines selected and then I try to set them again after the refreshing is done.

Try this :

1.- The lines selected are saved in a table.

CALL METHOD mo_alv_grid_edit->get_selected_rows

IMPORTING

et_index_rows = gi_index_rows.

call the table and then

2.- Set the lines I have before

CALL METHOD mo_alv_grid_edit->set_selected_rows

EXPORTING

it_index_rows = gi_index_rows .

Hi Sandeep,

what do you exactly mean with 'call the table' ?

when I call 'refresh_table_display' the outtab is update, so after this update because it is possible that new lines are added, I try to set the lines but everything is refresh so the focus come back to the first line.

just change the order of execution of the methods.

1 then 3 then 2

Hi Soumyaprakash,

I have already checked that but still doesn't work

[former_member194669]

In PBO of the screen

CALL METHOD mo_alv_grid_edit->set_selected_rows
EXPORTING
it_index_rows = gi_index_rows .  " Please ensure this have values

CALL METHOD mo_alv_grid_edit->refresh_table_display.

Hi again,

and thanks very much to all for your help.

There is info in the table that keeps the index, but method doesn't do anything.

[former_member194669]

As i mentioned whether do you removed soft_refresh from refresh_table_display ?

Please check the docu on soft_refresh

Is there a reason why you are doing a refresh ? Perhaps you can avoid a refresh and try.

Hi,

I have already tryed without the "refresh_table_display", but nothing happens the focus goes again to the first line.

[Former Member]

But do the lines remain selected ? If they do , then try passing IS_STABLE to the REFRESH_TABLE_DISPLAY method and see. Pass the row index of the first line that was selected in gi_index_rows by reading the table at index 1.

the entries remain, but after the refresh they dissappear. I thought that setting this lines again it would work but nothing happens. Indeed, after setting the entries I call again get_selected_rows to be sure that something was done, and it was the entries were selected but nothing is shown in the screen, the focus goes back to the first line

[Former Member]

But did you try with IS_STABLE parameter ?

*   Call the refresh
    DATA ls_stable TYPE lvc_s_stbl.
    ls_stable-row = 'X'.
    ls_stable-col = 'X'.

    CALL METHOD g_grid->refresh_table_display
      EXPORTING
        is_stable = ls_stable
      EXCEPTIONS
        finished  = 1
        OTHERS    = 2.

Now, the focus will remain on the row and column that you double clicked on.

You need to pass 'X' to the row and col field. Not the index as I had mentioned in my earlier post. Sorry about that.
