Hi ,

I have gone through the link. I have done the below part in my coding even though when i double click on the node, the event node_double_click is not getting triggered. Kindly suggest me what i have missed.

1) Register event with tree instance:

l_event-eventid = cl_gui_column_tree=>eventid_node_double_click.

APPEND l_event TO lt_events.

(2) Set handler for event:

SET HANDLER l_event_receiver->handle_node_double_click FOR tree1

(3) Define and implement event handler method:

METHODS handle_node_double_click

FOR EVENT node_double_click OF cl_gui_alv_tree

IMPORTING node_key.

ENDCLASS. "lcl_tree_event_receiver DEFINITION

CLASS lcl_tree_event_receiver IMPLEMENTATION

CLASS lcl_tree_event_receiver IMPLEMENTATION.

METHOD handle_node_double_click.

break-point.

ENDMETHOD. "handle_node_double_click

Ranjan

Hi,

Try to use this method call after you create the event table in step 1.

CALL METHOD g_tree->set_registered_events

EXPORTING

events = events.

g_tree is ref to the tree class.
