It sounds like you need to just manipulate the context when these events occur.

For the Add, use the context node BIND_ELEMENT to bind a new empty context:

For delete and copy you will need to read the leadSelection of the node. That will give you the element of selected record. For copy just call GET_STATIC_ATTRIBUTES on this this element. Then call BIND_ELEMENT with the structure returned from the previous method to bind the same data back into the context node as a new element.

Delete is easy. Once you have the element reference from the leadSelection, call REMOVE_ELEMENTof the context node object:

But basically you probably want to study these two help links and get familiar with the context APIs for such operations.

Hi Mahesh,

-> To add a new row to the table, you need to create and bind a new element to the node.

DATA: lo_nd_test TYPE REF TO if_wd_context_node,

lo_el_test TYPE REF TO if_wd_context_element,

ls_test TYPE wd_this->element_test.

lo_nd_test= wd_context->get_child_node( name = wd_this->wdctx_test ).

lo_el_test= lo_nd_test->create_element( ).

lo_nd_test->bind_element( new_item = lo_el_test set_initial_elements = abap_false ).

lo_nd_test->set_lead_selection( lo_el_test ). " to select the new row added

-> To delete the exisiting row, get the selected row element and call remove_element method.

lo_el_test= lo_nd_test->get_lead_selection( ).

lo_nd_test->remove_element( lo_el_test ).

-> To copy the existing row, get the values of the selected row using get_static_attributes( ) method and set the values to the new row added.

lo_nd_test= wd_context->get_child_node( name = wd_this->wdctx_test ).

lo_el_test= lo_nd_test->get_lead_selection( ).

check lo_el_test is not initial.

lo_el_test->get_Static_attributes( importing static_attributes = ls_test ).

clear lo_el_test.

lo_el_test= lo_nd_test->create_element( ).

lo_nd_test->bind_element( new_item = lo_el_test set_initial_elements = abap_false ).

lo_el_test->set_Static_attributes(EXPORTING static_attributes = ls_test ).
