Get selected function in a context menu with cl_gui_alv_grid

Question

Hi,
I'm trying to implement a context menu on a alv grid. I defined and implemented a method for the event CONTEXT_MENU_REQUEST to add function codes to context menu.  It works ok.
The problem is retrieving the function selected in context menu. I tried to define in the class definition a method for event CONTEXT_MENU_SELECTED (that seems to be the event to use) but  i can't implement it because is defined as protected event in CL_GUI_ALV_GRID.
How i can implement a method to catch this event and determine te function code defined in the context menu??
Thanks.

Answer 1

The tool bar isn't the best mechanism to use for selecting Rows etc but should ideally be used for discrete functions like SAVE, UPDATE, DOWNLOAD TO EXCEL etc.
For data manipulation look at ON DATA CHANGED, ON DATA CHANGED FINISHED and DOUBLE CLICK.
Probably the easiest way is to use the double click event
methods on_dubbelklik
    for event double_click of cl_gui_alv_grid
    importing
      !e_row
      !e_column
      !es_row_no .
methods dubbelklik
    importing
      !e_row type lvc_s_row
      !e_column type lvc_s_col
      !es_row_no type lvc_s_roid .
method constructor.
create object grid_container1
        exporting
           container_name = 'CCONTAINER1'.
    create object  grid1
       exporting
          i_parent = grid_container1.
    set handler z_object->on_user_command for grid1.
    set handler z_object->on_toolbar for grid1.
    set handler z_object->handle_data_changed for grid1.
    set handler z_object->handle_data_changed_finished for grid1.
    set handler z_object->on_dubbelklik for grid1.
    call method grid1->register_edit_event
        exporting
           i_event_id = cl_gui_alv_grid=>mc_evt_enter.
  endmethod.
method dubbelklik.
perform dubbelklik in program (caller)  if found
     using
      e_row
      e_column
      es_row_no.
endmethod.
Now in the application program
when a double click event is done the method calls routine dubbelklik in the calling program 
The row / column nr and field name will be passed to your subroutine.
(In my calling class for the grid I make the calling program one of the parameters);
form dubbelklik using
        e_row   type lvc_s_row
        e_column type lvc_s_col
        es_row_no type lvc_s_roid.
  read table <dyn_table> index e_row into wa_elements.
etc.
where <dyn_table> is my grid data table.
Any comparable method should work.
