Row data manipulation in WD SALV_WD_TABLE

Question

Dear Gurus,
I have a requirement in which i am using the standard WD component SALV_WD_TABLE in my custom WD component. Here i need to disable the checkbox in the first column based on a certain vallue in another column. Ex: I have the ALV displaying check box as first column followed by Purchase Order details like PO number, status, cost center etc. If the status has the value "Ordered" the checkbox should be displayed.
I tried to set the check box with method set_read_only(abap_true). But this disables check boxes on all rows. How do i do this conditionally. I found threads to do something for all rows in a column like setting a particular colour.
Regards,
Manidipa

Hi
Take one attribute READONLY type String
Take antoher internal table and move the contents of internal table to another to do manipulation and last bind the copied internal table.
method WDDOINIT .
  data : lo_nd_spfli_node TYPE REF TO if_wd_context_node,
         lo_el_spfli_noed TYPE REF TO if_wd_context_element,
         lt_sflight TYPE if_main=>elements_spfli_node,
         lt_final TYPE if_main=>elements_spfli_node,
         ls_final TYPE if_main=>element_spfli_node,
         ls_flight TYPE if_main=>element_spfli_node.
      lo_nd_spfli_node = wd_context->get_child_node( 'SPFLI_NODE' ).
SELECT * FROM
  SFLIGHT INTO CORRESPONDING FIELDS OF
  TABLE LT_SFLIGHT UP TO 60 ROWS.
  LOOP at lt_sflight into ls_flight.
    MOVE ls_flight to ls_final.
    if ls_final-carrid EQ 'AA'.
        ls_final-readonly = abap_FALSE.
    ELSE.
       ls_final-readonly = ' '.
    ENDIF.
    APPEND ls_final to lt_final.
  lo_nd_spfli_node->bind_table( lt_final ).
  ENDLOOP.
  DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
  l_ref_cmp_usage = wd_this->wd_cpuse_alv( ).
  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
  ENDIF.
DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
lo_interfacecontroller =   wd_this->wd_cpifc_alv( ).
  DATA lv_value TYPE REF TO cl_salv_wd_config_table.
  lv_value = lo_interfacecontroller->get_model(
CALL METHOD lv_value->if_salv_wd_table_settings~set_read_only
  EXPORTING
    value  = ABAP_FALSE
DATA:
lr_input_field TYPE REF TO cl_salv_wd_uie_input_field,
lr_column TYPE REF TO cl_salv_wd_column,
lr_cb TYPE REF TO CL_SALV_WD_UIE_CHECKBOX,
lr_column1 TYPE REF TO cl_salv_wd_column.
lr_column1 = lv_value->if_salv_wd_column_settings~get_column( 'READONLY' ).
CREATE OBJECT lr_cb
EXPORTING
CHECKED_FIELDNAME = 'READONLY'.
lr_column = lv_value->if_salv_wd_column_settings~get_column( 'CARRID' ).
CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'CARRID'.
lr_column1->set_cell_editor( lr_cb ).
lr_column->set_cell_editor( lr_input_field ).
lr_cb->set_read_only_fieldname( value = 'READONLY' ).
check with above code it works for your requirement
