How to bind dynamic checkbox to a table

Question

Hi,
I have a table that holds many fields. I put these fields on the screen dynamically.
I would like to bind a checkbox to select a field row.
I tried to bind the checkbox to the table but with no success. I keep getting the binding to the first element.
Does anyone has an example?
Thanks,
Itay

Hi P,
here is my code:
  LOOP AT lt_available_items ASSIGNING <item>.
    ADD 1 TO lv_col.
    IF lv_col > lv_cell_per_col.
      lv_col = 1.
      ADD 1 TO lv_row.
      lv_new_line = 'X'.
    ENDIF.
*   Add dynamic group
    CONCATENATE 'GROUP_' lv_col '_' lv_row INTO lv_str.
    lr_new_group = cl_wd_group=>new_group( id = lv_str view = view design = '02' ).
    IF lv_new_line = 'X'.
      CLEAR lv_new_line.
      cl_wd_matrix_head_data=>new_matrix_head_data( element = lr_new_group ).
    ELSE.
      cl_wd_matrix_data=>new_matrix_data( element = lr_new_group ).
    ENDIF.
    lr_new_group->set_width( '230' ).
    cl_wd_matrix_layout=>new_matrix_layout( container = lr_new_group ).
    lr_group->add_child( lr_new_group ).
*   Left side container
    CONCATENATE 'CONT_L_' lv_col '_' lv_row INTO lv_str.
    lr_new_container = cl_wd_transparent_container=>new_transparent_container(
          id = lv_str view = view ).
    cl_wd_matrix_head_data=>new_matrix_head_data( element = lr_new_container ).
    cl_wd_matrix_layout=>new_matrix_layout( container = lr_new_container ).
    lr_new_group->add_child( lr_new_container ).
*   Add checkbox
    CONCATENATE 'CHK_' lv_col '_' lv_row INTO lv_str.
    lr_checkbox = cl_wd_checkbox=>new_checkbox( view   = view
                                                id     = lv_str ).
    lr_matrix_head = cl_wd_matrix_head_data=>new_matrix_head_data( element = lr_checkbox ).
    lr_checkbox->set_layout_data( lr_matrix_head ).
    lr_checkbox->bind_checked( 'AVAILBLE_ITEMS.SELECTED' ).
    lr_new_container->add_child( lr_checkbox ).
endloop.
my node is AVAILABLE_ITEMS and it has the attributes: SELECTED, MATNR, MAKTX...
thanks,
