Hi,

Pls refer the Demo Program WDT_TREE.

Define the action "onLoadChildren" of the tree node. In the event handler for this action, write your code to fetch children.

hi reema,

this is the code for populating the node:

DATA lo_nd_appr_tree_temp TYPE REF TO if_wd_context_node.

DATA lo_el_appr_tree_temp TYPE REF TO if_wd_context_element.

DATA ls_appr_tree_temp TYPE wd_this->Element_appr_tree_temp.

• navigate from <CONTEXT> to <APPR_TREE_TEMP> via lead selection

lo_nd_appr_tree_temp = wd_context->get_child_node( name = wd_this->wdctx_appr_tree_temp ).

• get element via lead selection

lo_el_appr_tree_temp = lo_nd_appr_tree_temp->get_element( ).

CALL METHOD lo_nd_appr_tree_temp->CREATE_ELEMENT

• EXPORTING

• STATIC_ATTRIBUTE_VALUES =

RECEIVING

ELEMENT = lo_el_appr_tree_temp.

CALL METHOD lo_nd_appr_tree_temp->BIND_ELEMENT

EXPORTING

NEW_ITEM = lo_el_appr_tree_temp

• SET_INITIAL_ELEMENTS = ABAP_TRUE

• INDEX =

RECEIVING

ELEMENT = lo_el_appr_tree_temp.

ls_appr_tree_temp-TEMP_TYPE = 'NODE'.

ls_appr_tree_temp-HAS_CHILD = 'X'.

CALL METHOD lo_el_appr_tree_temp->SET_STATIC_ATTRIBUTES

EXPORTING

• INDEX = USE_LEAD_SELECTION

STATIC_ATTRIBUTES = ls_appr_tree_temp.

can you please tell me how to populate the children.

please reply soon.

Thanks,

Ritwik.
