Check Box in Tree View

[Former Member]

I have created ALV TREE VIEW using CL_GUI_ALV_TREE.

i have set the check boxes at nodes.

now whenever user checks the checkbox and selects the pushbutton on PF-Status..at that time i want to capture the checkbox in my internal table...

please fine me a solution.

Thanks.

Following code is to add checkboxes in ALV tree:

FORM add_root_request USING pls_data_ TYPE csg_gs_outtab_p_key__l_is_sub_node_ TYPE c

CHANGING pl_carrid_key._node = nodes->add_node( related_node = p_key

relationship = cl_gui_column_tree=>relat_last_child ).

• ... §0.2 if information should be displayed at

• the hierarchy column set the carrid as text for this node

text = p_ls_data-object.

node->set_text( text ).

• ... §0.3 set the data for the nes node

node->set_data_row( p_ls_data ).

item = node->get_hierarchy_item( ).

item = node->get_item( 'FCHECKBOX' ). "FCHECKBOX is my radio button field in internal table which I am using to populate the ALV

item->set_type( if_salv_c_item_type=>checkbox ).

pl_carrid_key = node->get_key( )._

CATCH cx_salv_msg.

ENDFORM_._Following code is for handling checbox_change event
