Regarding Node methods........?

Question

Hi all,
In my scenario ,i have a column of chekboxes in my ALV.aftr that user can select any no checkboxes.
whwn user check on checkbox,the record must selected and finally i have to pass all those selected records into on table.
how can do it?
method ON_DATA_CHECK .
data:
    Node_Ep_Sch_Info                    type ref to If_Wd_Context_Node,
    Elem_Ep_Sch_Info                    type ref to If_Wd_Context_Element,
    lt_Ep_Sch_Info                    type If_Ep_Sch_Details=>Elements_Ep_Sch_Info ,
    ls_Ep_Sch_Info                    type If_Ep_Sch_Details=>Element_Ep_Sch_Info ,
     lv_checked                       type If_Ep_Sch_Details=>Element_Ep_Sch_Info-CHK_BOX.
     Node_Ep_Sch_Info = wd_Context->get_Child_Node( Name = IF_EP_SCH_DETAILS=>wdctx_Ep_Sch_Info ).
  Node_ep_sch_info->get_static_attributes_table( importing TABLE = lt_ep_sch_info ).
LOOP AT LT_EP_SCH_INFO INTO LS_EP_SCH_INFO.
IF LV_CHECKED EQ 'X'.
Node_ep_sch_info->SET_SELECTED( ).
ENDIF.
ENDLOOP.
    Node_ep_sch_info->GET_SELECTED_ELEMENTS( ).
endmethod.
i used above scenario.here what is the return type of GET_SELECTED_ELEMENTS( ).how can i pass these selected elements into one table?

Hi ravi
Create a internal table it_newdata having same structure as your context node, to do so:
Data: it_newdata   type  IF_viewname=>elements_nodename.
Say if I have a view called DISPALY having a context node 'DATA'  then to declare a internal table having the same line type as of attributes of data write:
Data: it_newdata  type if_display=>elements_data,
       ls_newdata   like line of  it_newdata.      " work area
Now as I mention in my previous reply in the loop statement, fill the internal table it_newdata .
loop at it_selected_row into ls_selected_row.
*get all the attributes of every element
CALL METHOD ls_selected_row->get_static_attributes
IMPORTING
static_attributes = stru_Ep_Sch_Info.
ls_newdata-attrib1 = stru_Ep_Sch_Info-attrib1.
ls_newdata-attrib2 = stru_Ep_Sch_Info-attrib2.
ls_newdata-attrib3 = stru_Ep_Sch_Info-attrib3.
append ls_newdata to it_newdata .
clear: ls_newdata.
endloop.
Read your node say : DATA using code wizard which you want to fill. It will give you stryu_data, elem_data and node_data. use node_data
Now bind the data to the context node
  Node->Bind_Table(
    New_Items =  it_newdata
    Set_Initial_Elements = Abap_True ).
