Hi Neeraj

I have implemented the same thing recentlly

I tried a lot to find atleast one method to deselect checkboxs in tree structure (cl_gui_alv_tree)

but there is no special method to uncheck/check checkboxes.

ya there are methods to select node/leaf- but I guess this is not what u want.

U can only use change_node method of class :cl_gui_alv_tree,

refer this code :-

DATA : lt_layout_chk_edit TYPE lvc_t_laci,

lt_layout_chk_noedit TYPE lvc_t_laci,

lt_layout_nochk_edit TYPE lvc_t_laci,

lt_layout_nochk_noedit TYPE lvc_t_laci.

********************************

CLEAR ls_layout.

filling layout for package (EDITABLE AND CHECKED)

ls_layout-fieldname = gref_tree_manual->c_hierarchy_column_name.

ls_layout-class = cl_gui_column_tree=>item_class_checkbox.

ls_layout-editable = gc_charx.

ls_layout-disabled = ' '.

ls_layout-chosen = gc_charx.

ls_layout-u_disabled = gc_charx.

ls_layout-u_editable = gc_charx.

ls_layout-u_chosen = gc_charx.

APPEND ls_layout TO lt_layout_chk_edit.

CLEAR ls_layout.

filling layout for package (NONEDITABLE AND CHECKED)

ls_layout-fieldname = gref_tree_manual->c_hierarchy_column_name.

ls_layout-class = cl_gui_column_tree=>item_class_checkbox.

ls_layout-editable = ' '.

ls_layout-disabled = gc_charx.

ls_layout-chosen = gc_charx.

ls_layout-u_disabled = gc_charx.

ls_layout-u_editable = gc_charx.

ls_layout-u_chosen = gc_charx.

APPEND ls_layout TO lt_layout_chk_noedit.

CLEAR ls_layout.

filling layout for package (EDITABLE AND NON-CHECKED)

ls_layout-fieldname = gref_tree_manual->c_hierarchy_column_name.

ls_layout-class = cl_gui_column_tree=>item_class_checkbox.

ls_layout-editable = gc_charx.

ls_layout-disabled = ' '.

ls_layout-chosen = ' '.

ls_layout-u_disabled = gc_charx.

ls_layout-u_editable = gc_charx.

ls_layout-u_chosen = gc_charx.

APPEND ls_layout TO lt_layout_nochk_edit.

CLEAR ls_layout.

filling layout for package display(NONEDITABLE AND NON-CHECKED)

ls_layout-fieldname = gref_tree_manual->c_hierarchy_column_name.

ls_layout-class = cl_gui_column_tree=>item_class_checkbox.

ls_layout-editable = ' '.

ls_layout-disabled = gc_charx.

ls_layout-chosen = ' '.

ls_layout-u_disabled = gc_charx.

ls_layout-u_editable = gc_charx.

ls_layout-u_chosen = gc_charx.

APPEND ls_layout TO lt_layout_nochk_noedit.

*******************************

loop at your tree table - which contains all the nodes- for which u want to change the checkbox status (parent/child anything)

this will give u rough idea.....

LOOP AT gt_nodes INTO ls_nodes.

CLEAR ls_outtab.

CALL METHOD gref_tree->get_outtab_line

EXPORTING

i_node_key = ls_nodes-node_key

IMPORTING

e_outtab_line = ls_outtab

EXCEPTIONS

node_not_found = 1

OTHERS = 2.

to make check box (EDITABLE AND NON-CHECKED)

CALL METHOD gref_tree_alacarte->change_node

EXPORTING

i_node_key = ls_nodes-node_key

i_outtab_line = ls_outtab

it_item_layout = lt_layout_nochk_edit

EXCEPTIONS

node_not_found = 1

OTHERS = 2.

endloop.

neeraj, i think this will help u a lot.

Reward if it is helpfull.

regards,

Mihir Nagar.
