Hi,

Check this demo program BCALV_TREE_MOVE_NODE_TEST

Hi,

Use the method suggested by richard expand_root_nodes.

Anyhow to work this when clicked on expand button you need to handle event EXPAND_NO_CHILDREN. Inside the handler write the above method. Each time user opens a folder (with attribute EXPANDER = 'X') all the others will be expanded.

Is that what you requirement?

Try this:

CALL METHOD CL_GUI_COLUMN_TREE=>expand_nodes

or

CALL METHOD CL_GUI_COLUMN_TREE=>expand_root_nodes

hi the same thing is used in all the programs...see below

BCALV_TEST_COLUMN_TREE

BCALV_TEST_SIMPLE_TREE

BCALV_TREE_01

BCALV_TREE_02

BCALV_TREE_03

BCALV_TREE_04

BCALV_TREE_05

BCALV_TREE_06

BCALV_TREE_DEMO

like this ..

create object gr_container

exporting container_name = 'TREE_CONTAINER'.

data: l_hierarchy_header type treev_hhdr,

l_width type i value 50.

l_hierarchy_header-heading = 'HEADER'.

l_hierarchy_header-width = l_width.

create object gr_tree

exporting

parent = gr_container

node_selection_mode =

cl_gui_column_tree=>node_sel_mode_multiple

item_selection = 'X'

hierarchy_column_name = 'COLUMN'

hierarchy_header = l_hierarchy_header.

Class [CL_GUI_COLUMN_TREE|https://www.sdn.sap.com/irj/scn/advancedsearch?query=cl_gui_column_tree&cat=sdn_all] inherit methods of class [CL_TREE_CONTROL_BASE|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=cl_tree_control_base&adv=false&sortby=cm_rnd_rankvalue], so just use the method [expand_root_nodes|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=expand_root_nodes&adv=false&sortby=cm_rnd_rankvalue]

CALL METHOD tree->expand_root_nodes
  EXPORTING  level_count = level_count
             expand_subtree = expand_subtree
  EXCEPTIONS failed = 1
             illegal_level_count = 2
             cntl_system_error = 3.

Where level_count :

- 0: Only the root nodes are expanded - no underlying nodes.

- 1: The current node and the next hierarchy level are expanded.

and expand_subtree

- 'X': Expands all nodes in the subtree. The system ignores any value of LEVEL_COUNT

To collapse all nodes use method [COLLAPSE_ALL_NODES|https://www.sdn.sap.com/irj/scn/advancedsearch?query=collapse_all_nodes&cat=sdn_all]

Look at [SAP Tree and Tree Model (BC-CI)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCITREE/BCCITREE.pdf] or [SAP Tree Model|http://help.sap.com/erp2005_ehp_04/helpdata/EN/4a/0f753824a34f47e10000009b38f8cf/frameset.htm] for documentation and read SAP demo programs like SAPCOLUMN_TREE_CONTROL_DEMO, SAPSIMPLE_TREE_CONTROL_DEMO, and

SAPTLIST_TREE_CONTROL_DEMO, BCALV_TREE_SIMPLE_DEMO and BCALV_TREE_DEMO
