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 .

BT_DEL代码部分：

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：

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

* 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。
