ALV Tree drop down not working

[Former Member]

This is an ALV Tree.

When I press the drop down(red circle), nothing happen.

I did a test on my program.

When I take off Register_Event, it works fine.

Please advice.

*Register events for alv tree
     PERFORM REGISTER_EVENT.

Hi Wong,

what does register_event do? I'd guess it registers the event that is executed when a node is expanded and you are not handling that event in your code or something similar.

This is my Register_event.

Basically, register a item double click event. So when there is double click event, it will pass to

another place to catch the nodekey and the fieldname.

form REGISTER_EVENT .
 
 *Define local variables
   DATA: lt_events        TYPE cntl_simple_events,
         l_event          TYPE cntl_simple_event.
 
 *Frontend registration: add additional event ids
   l_event-eventid = cl_gui_column_tree=>eventid_item_double_click.
   append l_event to lt_events.
 
 *Frontend registration:provide new event table to alv tree
 call method g_alv_tree->set_registered_events
     exporting
       events = lt_events
     exceptions
       cntl_error                = 1
       cntl_system_error         = 2
       illegal_event_combination = 3.
   if sy-subrc <> 0.
     message x208(00) with 'ERROR'.                       "#EC NOTEXT
   endif.
 
 
 data: l_event_receiver type ref to lcl_tree_event_receiver.
   create object l_event_receiver.
 
    set handler l_event_receiver->handle_item_double_click
                                                         for g_alv_tree.
 
 endform.                    " FM_REGISTER_EVENT
