After adding the dropdown there is an event called ON_ALV_TOOLBAR which triggers upon any action on ALV toolbar. Make use of that for the event handling purpose.

Hi Raghu,

Make use below code :

method WDDOINIT .
  DATA:
lo_node_cskt TYPE REF TO if_wd_context_node,
lo_el_cskt TYPE REF TO if_wd_context_element,
ls_cskt TYPE wd_this->element_cskt,
lt_cskt TYPE wd_this->elements_cskt,
lo_cmp_usage TYPE REF TO if_wd_component_usage,
lv_value TYPE REF TO cl_salv_wd_config_table,
lr_column TYPE REF TO cl_salv_wd_column,
lr_drdn TYPE REF TO cl_salv_wd_uie_dropdown_by_idx,
ls_value_set TYPE wdr_context_attr_value,
lv_tabix TYPE sy-tabix,
lv_count(2) TYPE c,
lo_interfacecontroller TYPE REF TO iwci_salv_wd_table.

* Navigate from <CONTEXT> to <CSKT> via lead selection:
lo_node_cskt = wd_context->get_child_node( name = wd_this->wdctx_cskt ).

* get element via lead selection
lo_el_cskt = lo_node_cskt->get_element( ).

* Get Data:
SELECT kokrs kostl datbi ktext FROM cskt INTO CORRESPONDING FIELDS OF TABLE lt_cskt up to 10 rows .

lv_count = 0.

* Populate value set
LOOP AT lt_cskt INTO ls_cskt.
lv_tabix = sy-tabix.
CLEAR ls_cskt-ktext.
DO 3 TIMES.
lv_count = lv_count + 1.
CONCATENATE 'TEST' lv_count INTO ls_value_set-text.
CONCATENATE 'TEST' lv_count INTO ls_value_set-value.
if lv_tabix = 2.
if sy-index = 2.
EXIT.
endif.
endif.
APPEND ls_value_set TO ls_cskt-valueset.
ENDDO.

MODIFY lt_cskt FROM ls_cskt INDEX lv_tabix TRANSPORTING ktext valueset.
ENDLOOP.

* Bind data
lo_node_cskt->bind_table( lt_cskt ).

* Instantiate ALV
lo_cmp_usage = wd_this->wd_cpuse_alv( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
lo_cmp_usage->create_component( ).
ENDIF.

lo_interfacecontroller = wd_this->wd_cpifc_alv( ).

* Bind Data to Interface Controller Node
lo_interfacecontroller->set_data(
r_node_data = lo_node_cskt
).

* Get ALV reference table
lv_value = lo_interfacecontroller->get_model( ).

* Make KTEXT column as drop down
CALL METHOD lv_value->if_salv_wd_column_settings~get_column
EXPORTING
id = 'KTEXT'
RECEIVING
value = lr_column.

* Create Object for Drop down
CREATE OBJECT lr_drdn
EXPORTING
selected_key_fieldname = 'KTEXT'.

CALL METHOD lr_drdn->set_valueset_fieldname
EXPORTING
value = 'VALUESET'.
CALL METHOD lr_drdn->set_type
EXPORTING
value = IF_SALV_WD_C_UIE_DRDN_BY_INDEX=>TYPE_KEY_CONVERT_TO_VALUE.

CALL METHOD lr_column->set_cell_editor
EXPORTING
value = lr_drdn.

CALL METHOD lv_value->if_salv_wd_table_settings~set_read_only
EXPORTING
value = abap_false.
endmethod.
