Hi
Following code is to add checkboxes in ALV tree:
FORM add_root_request USING pls_data_ TYPE csg_gs_outtab_p_key__l_is_sub_node_ TYPE c
CHANGING pl_carrid_key._node = nodes->add_node( related_node = p_key
relationship = cl_gui_column_tree=>relat_last_child ).
... §0.2 if information should be displayed at
the hierarchy column set the carrid as text for this node
text = p_ls_data-object.
node->set_text( text ).
... §0.3 set the data for the nes node
node->set_data_row( p_ls_data ).
item = node->get_hierarchy_item( ).
item = node->get_item( 'FCHECKBOX' ). "FCHECKBOX is my radio button field in internal table which I am using to populate the ALV
item->set_type( if_salv_c_item_type=>checkbox ).
pl_carrid_key = node->get_key( )._
CATCH cx_salv_msg.
ENDFORM_._Following code is for handling checbox_change event
PERFORM application_action_events.
FORM application_action_events .
data: lr_events type ref to cl_salv_events_tree.
*data gr_events type ref to lcl_handle_events.
lr_events = gr_tree->get_event( ).
create object gr_events.
set handler gr_events->check for lr_events.
set handler gr_events->on_link_click for lr_events.
set handler gr_events->on_before_user_command for lr_events.
