Hi,

You can create a Custom Container through the Dynpro. That is all you need to embed the Tree Control. As such there is nothing called Tree Container.

Below is a sample code for the Custom Container.



  CREATE OBJECT l_custom_container
        EXPORTING
          container_name              = l_tree_container_name
        EXCEPTIONS
          cntl_error                  = 1
          cntl_system_error           = 2
          create_error                = 3
          lifetime_error              = 4
          lifetime_dynpro_dynpro_link = 5.
      IF sy-subrc <> 0.
        MESSAGE x208(00) WITH 'ERROR'.                      "#EC NOTEXT
      ENDIF.
    ENDIF.

* create tree control
    CREATE OBJECT tree2
      EXPORTING
        parent                      = l_custom_container
        node_selection_mode         = cl_gui_column_tree=>node_sel_mode_single
        item_selection              = 'X'
        no_html_header              = ''
        no_toolbar                  = ''
      EXCEPTIONS
        cntl_error                  = 1
        cntl_system_error           = 2
        create_error                = 3
        lifetime_error              = 4
        illegal_node_selection_mode = 5
        failed                      = 6
        illegal_column_name         = 7.
    IF sy-subrc <> 0.
      MESSAGE x208(00) WITH 'ERROR'.                        "#EC NOTEXT
    ENDIF.

l_custom_container is the variable that will contain the name of the custom container that you defined in the Dynpro.

Thanks,

Samantak.
