Author: Puru Govind

This code snippet will check (the checkboxes) all the parent nodes. Note to get the parent of the parent, I am calling the method recursively. Please note that, I am copying the code of my application verbatim here. Please make changes accordingly.

Code:
*Get the current node
CALL METHOD go_nodes_update->get_node
EXPORTING
node_key = node_key
RECEIVING
value = lo_node.
.

TRY.
CALL METHOD lo_node->get_parent "get its parent
RECEIVING
value = lo_parent_node.
CALL METHOD lo_parent_node->get_key "Get parents key
RECEIVING
value = lv_parent_key.

IF checked = abap_true. "set the parent
CALL METHOD check "call this method again
EXPORTING
node_key = lv_parent_key
columnname = 'U_EN'
checked = abap_true.
item = lo_node->get_item( 'U_EN' ).
item->set_checked( abap_true ).
ELSE.
CALL METHOD check "unset the parents
EXPORTING
node_key = lv_parent_key
columnname = 'U_EN'
checked = abap_false.
item = lo_node->get_item( 'U_EN' ).
item->set_checked( abap_false ).
ENDIF.


CATCH cx_salv_msg .
ENDTRY.
