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：
method bt_add . data: lo_nd_zsmm_mat type ref to if_wd_context_node, lo_el_zsmm_mat type ref to if_wd_context_element, ls_zsmm_mat type wd_this->element_zsmm_material. lo_nd_zsmm_mat = wd_context->get_child_node( name = wd_this->wdctx_zsmm_material ). ls_zsmm_mat-fg_read = abap_false.

BT_CHG代码部分：
method bt_chg . 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. clear: wd_this->gv_message. lo_api_controller ?= wd_this->wd_get_api( ).

BT_DEL代码部分：
method bt_del . data: lo_window_manager type ref to if_wd_window_manager, lo_popup_window type ref to if_wd_window, lo_cmp_api type ref to if_wd_component, lt_text type string_table, lv_titlebar type string. lo_cmp_api = wd_this->wd_get_api( ). lo_window_manager = lo_cmp_api->get_window_manager( ). lv_titlebar = wd_assist->get_text( key = 'M03' ). wd_this->gv_message = wd_assist->get_text( key = 'M04' ). append wd_this->gv_message to lt_text. call method lo_window_manager->create_popup_to_confirm exporting text = lt_text button_kind = if_wd_window=>co_buttons_yesno message_type = if_wd_window=>co_msg_type_warning close_button = abap_false window_title = lv_titlebar window_position = if_wd_window=>co_center default_button = if_wd_window=>co_button_yes receiving result = lo_popup_window. try. lo_popup_window->popup_to_confirm->subscribe_to_button_event( controller = lo_cmp_api handler_name = 'HNDL_POP_YES' button = if_wd_window=>co_button_yes ). catch cx_wdr_rt_exception. endtry. try. lo_popup_window->popup_to_confirm->subscribe_to_button_event( controller = lo_cmp_api handler_name = 'HNDL_POP_NO' button = if_wd_window=>co_button_no ). 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( ).

"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。
