Hello Colleagues,

I am still unable to update the node_key value after deleting the nodes.

I have used the following snippet

CALL METHOD gr_tree_ui->get_selected_node
IMPORTING
es_row = ls_row.


CALL METHOD cl_gui_cfw=>flush.

CALL METHOD mr_tree->delete_subtree
EXPORTING
i_node_key = ls_selected_node
i_update_parents_folder = abap_true
EXCEPTIONS
node_key_not_in_model = 1
OTHERS = 2.


CALL METHOD mr_tree->frontend_update.

Regards,

Naga

The method updating the screen is CALL METHOD cl_gui_cfw=>flush. so you have to call it AFTER CALL METHOD mr_tree->frontend_update.
