Hi all,

I'm using the class cl_gui_alv_tree_simple. After displaying the tree, the cursor is positionned at the end of the list...

How can I display the tree and set the position on top of the list ?

thank you

Use set_select_nodes method passing node id of top node


 DATA lt_nd_sel TYPE lvc_t_nkey.

  APPEND top_node_id TO lt_nd_sel.
  go_alv_tree->set_selected_nodes( lt_nd_sel ).

Regards

Marcin

Hi,

thanks for your answer, but how do you define/implement this Method ? I never used it before...

Where does top_node_id come from ?

thank you
