Multiple row selection for table element

Question

Hi,
I have a requirement where I require to select multiple rows from a table element in a WD for abap application.
I have defined a node with cardinality and selection set to 1..n.
The contex node contains 4 fields : emp_name, pernr, manager and position.
The attributes of the table element for selectionmode is set to 'multi' and 'selectionchangebehaviour' is set to 'auto'.
I have defined an action on the 'onleadselection' event.
The code in this method also includes the statement 'lo_el_team_view->set_selected( EXPORTING flag = abap_true ).' 
When I execute the application only 1 row is highlighted at any one time when I select it. You can select multiple rows by holding down the 'ctrl' key but I want to avoid having to do this. Is there anything I have missed out causing multiple row selections not to be all highlighted.
Thanks in advance for any assistance.

Hi raj,
you can try the following code in the 'onleadselect' event of the table,
create one attribute ' Flag'  of type WDY_BOOLEAN under the node which has been binded to the table.
DATA lo_nd_node_tab1 TYPE REF TO if_wd_context_node.
  DATA lo_el_node_tab1 TYPE REF TO if_wd_context_element.
  DATA  lo_elements TYPE wdr_context_element_set.
  DATA  lo_ele_select_new TYPE REF TO if_wd_context_element.
  DATA lv_deselect TYPE wdy_boolean.
  DATA lv_flag TYPE wdy_boolean.
  DATA lv_select TYPE wdy_boolean.
  DATA lv_index TYPE i VALUE 0.
  lo_nd_node_tab1 = wd_context->get_child_node( name = wd_this->wdctx_node_tab1 ).
get the current selected element
  lo_ele_select_new = wdevent->get_context_element( name = 'NEW_ROW_ELEMENT' ).
  CHECK lo_ele_select_new IS NOT INITIAL.
check whether it has been selected or not
  CALL METHOD lo_ele_select_new->is_selected
    RECEIVING
      flag = lv_select.
  lo_ele_select_new->get_attribute( EXPORTING name = 'FLAG' IMPORTING value = lv_deselect ).
check whether element has been previously selected or not,if not, set the flag to select it
IF lv_select IS NOT INITIAL AND lv_deselect IS INITIAL.
    lo_ele_select_new->set_attribute( name = 'FLAG' value = 'X' ).
if selected currently and previously then set the flag as false,in order to delect it
  ELSEIF lv_select IS NOT INITIAL AND lv_deselect IS NOT INITIAL..
    lo_ele_select_new->set_attribute( name = 'FLAG' value = ' ' ).
  ENDIF.
  CALL METHOD lo_nd_node_tab1->get_elements
    RECEIVING
      set = lo_elements.
according to the falg, select and delect the elements
LOOP AT lo_elements INTO lo_el_node_tab1.
    lo_el_node_tab1->get_attribute( EXPORTING name = 'FLAG' IMPORTING value = lv_flag ).
    IF lv_flag = 'X'.
      lo_el_node_tab1->set_selected( abap_true ).
      lo_nd_node_tab1->set_lead_selection_index( lv_index ).  * this statement deselects the lead selection index*
    ELSE.
      lo_el_node_tab1->set_selected( abap_false ).
      lo_nd_node_tab1->set_lead_selection_index( lv_index ).
    ENDIF.
  ENDLOOP.
I hope this resolves your problem.
Thanks,
krishna
