　ALV按钮增加后需要触发，则需要添加ON_FUNCTION事件，如下图BT_ALV_FUN：

　

　BT_ALV_FUN事件代码：

method bt_alv_fun .

  case r_param->id.
    when 'BT_ADD'.     bt_add( ).　　"新增
    when 'BT_CHG'.     bt_chg( ).　　"修改
    when 'BT_DEL'.     bt_del( ).　　"删除
    when 'BT_SAVE'.    bt_save( ).　 "保存
    when others.
  endcase.

endmethod.

上述代码中不同的按钮调用不同的方法，该方法需要在控制器中进行定义：

BT_ADD代码部分：

    return.
  endif.

  loop at lt_el_zsmm_mat into lo_el_zsmm_mat.

    lo_el_zsmm_mat->set_static_attributes(  static_attributes = ls_zsmm_mat ).

BT_DEL代码部分：

  try.
      lo_popup_window->popup_to_confirm->subscribe_to_button_event(

    catch cx_wdr_rt_exception.
  endtry.

  lo_popup_window->open( ).
endmethod.

上述代码中增加了弹出窗口POPUP_TO_CONFIRM，则需要针对不同的选择结果添加不同的触发事件。

选择'是'，则调用HNDL_POP_YES，选择'否'，则调用HNDL_POP_NO。

两个事件需要在控制器中添加：

HNDL_POP_YES事件代码：

method hndl_pop_yes .

  data:
    lo_nd_zsmm_mat     type ref to if_wd_context_node,
    lt_el_zsmm_mat     type wdr_context_element_set,
    lo_el_zsmm_mat     type ref to if_wd_context_element,
    ls_zsmm_mat        type wd_this->element_zsmm_material,
    lt_zsmm_mat        type wd_this->elements_zsmm_material,
    lo_api_controller  type ref to if_wd_controller,
    lo_message_manager type ref to if_wd_message_manager.
  data:
    lv_iserror type abap_bool.
  field-symbols:
    <fs_zsmm_mat>     type wd_this->element_zsmm_material.

  clear: wd_this->gv_message.

  lo_api_controller ?= wd_this->wd_get_api( ).

  "消息
  lo_message_manager = lo_api_controller->get_message_manager( ).

  lo_nd_zsmm_mat = wd_context->get_child_node( name = wd_this->wdctx_zsmm_material ).
  lo_el_zsmm_mat = lo_nd_zsmm_mat->get_element( ).

  "获取选择行数据
*  lt_el_zsmm_mat = lo_nd_zsmm_mat->get_selected_elements( including_lead_selection = abap_true ).
*  if lt_el_zsmm_mat is initial.
*    wd_this->gv_message = wd_assist->get_text( key = 'M01' ).
*    lo_message_manager->report_error_message( message_text = wd_this->gv_message ).
*    return.
*  endif.

  clear: lt_zsmm_mat, lv_iserror.
  lo_el_zsmm_mat->get_static_attributes( importing static_attributes = ls_zsmm_mat ).
  lo_nd_zsmm_mat->get_static_attributes_table( importing table = lt_zsmm_mat ).

  loop at lt_zsmm_mat assigning <fs_zsmm_mat>
  where matnr = ls_zsmm_mat-matnr.
    delete lt_zsmm_mat.
  endloop.

  lo_nd_zsmm_mat->bind_table( lt_zsmm_mat ).
  lo_message_manager->report_success( message_text = wd_assist->get_text( key = 'M05') ).

endmethod.

HNDL_POP_NO触发事件暂不做处理。

BT_SAVE保存方法暂不做处理。

2.2测试

选择WebDynpro应用程序，点击执行按钮。

界面新增了4个按钮：新建/修改/删除/保存。

查询记录：

新建：

修改：

删除：

上述步骤基本完成ALV控件的新建/修改/删除操作。
