ALV table - get row number clicked

[Former Member]

I have a very simple ALV table in a view in my application. The view also contains a button. On clicking the button, I need to add code to the method to determine the row number selected in the ALV table. Someone suggested using:

DATA lt_selected_rows TYPE lvc_t_roid .
DATA ls_selected_row TYPE lvc_s_roid .
CALL METHOD gr_alvgrid->get_selected_rows
IMPORTING
et_row_no = lt_selected_rows .
READ TABLE lt_selected_rows INTO ls_selected_row INDEX 1 .
IF sy-subrc ne 0 .
ENDIF

but the code is missing the declaration and the initialization of the variable gr_alvgrid.

Any help would be truly appreciated.

OK, I added the data declaration. My module now looks like:

METHOD onactiondelete_row .
  DATA gr_alvgrid TYPE REF TO cl_gui_alv_grid.
  DATA lt_selected_rows TYPE lvc_t_roid .
  DATA ls_selected_row TYPE lvc_s_roid .
  CALL METHOD gr_alvgrid->get_selected_rows  
     IMPORTING   
        et_row_no = lt_selected_rows. 
  READ TABLE lt_selected_rows INTO ls_selected_row INDEX 1 .
  IF sy-subrc NE 0 .
  ENDIF.
ENDMETHOD.

I get a dump on the call method:

OBJECTS_OBJREF_NOT_ASSIGNED

Please help

Hi DeNuto,

Try using:

DATA gr_alvgrid TYPE REF TO CL_GUI_ALV_GRID.
