好了，这个是个人测试玩的，略风骚。。。请自行鉴阅
1.明细的组件控制器中增加全局控制属性字段：
2.概览页中工具栏相关方法，重定义GET_BUTTONS
METHOD IF_BSP_WD_TOOLBAR_CALLBACK~GET_BUTTONS.
DATA:LV_LOCK TYPE ABAP_BOOL VALUE ABAP_TRUE,
LV_ENABLE TYPE ABAP_BOOL VALUE ABAP_FALSE.
DATA:LR_COM TYPE REF TO ZL_ZLYTEST0_BSPWDCOMPONE3_IMPL.
DATA:RW_BUTTON TYPE CRMT_THTMLB_BUTTON_EXT. CALL METHOD SUPER->IF_BSP_WD_TOOLBAR_CALLBACK~GET_BUTTONS
RECEIVING
RT_BUTTONS = RT_BUTTONS. LR_COM ?= ME->COMP_CONTROLLER.
CHECK LR_COM IS BOUND.
IF LR_COM->DISPLAY = ABAP_TRUE.
LV_ENABLE = ABAP_FALSE.
ELSE.
LV_ENABLE = ABAP_TRUE.
ENDIF. RW_BUTTON-TYPE = CL_THTMLB_UTIL=>GC_ICON_SAVE.
RW_BUTTON-ON_CLICK = 'SAVE'.
RW_BUTTON-PAGE_ID = ME->COMPONENT_ID.
RW_BUTTON-ENABLED = LV_ENABLE.
APPEND RW_BUTTON TO RT_BUTTONS. RW_BUTTON-TYPE = CL_THTMLB_UTIL=>GC_ICON_CANCEL.
RW_BUTTON-ON_CLICK = 'CANCEL'.
RW_BUTTON-PAGE_ID = ME->COMPONENT_ID.
RW_BUTTON-ENABLED = LV_ENABLE.
APPEND RW_BUTTON TO RT_BUTTONS. ENDMETHOD.
3.概览页中工具栏相关方法，重定义GET_NUMBER_OF_VISIBLE_BUTTONS
METHOD IF_BSP_WD_TOOLBAR_CALLBACK~GET_NUMBER_OF_VISIBLE_BUTTONS.
RV_RESULT = .
ENDMETHOD.
4.DETAIL视图的实现类中定义属性：
5.DETAIL视图中，重定义DO_PREPARE_OUTPUT
DATA:LS_BUTTON TYPE CRMT_THTMLB_BUTTON.
CALL METHOD SUPER->DO_PREPARE_OUTPUT. REFRESH GT_BUTTON.
CLEAR:LS_BUTTON.
LS_BUTTON-TYPE = CL_THTMLB_UTIL=>GC_ICON_EDIT.
LS_BUTTON-TEXT = CL_WD_UTILITIES=>GET_OTR_TEXT_BY_ALIAS( 'CRM_UIU_BU/EDIT' ).
LS_BUTTON-ENABLED = ABAP_TRUE."此处可酌情控制
LS_BUTTON-ON_CLICK = 'EDIT'.
APPEND LS_BUTTON TO GT_BUTTON.
ENDMETHOD.
6.修改DETAIL的htm页面：用本地的变量控制配置页
<%@page language="abap" %>
<%@extension name="thtmlb" prefix="thtmlb" %>
<%@extension name="chtmlb" prefix="chtmlb" %>
<%@extension name="bsp" prefix="bsp" %>
<%
data:LV_XML type STRING,
LV_DISPLAYMODE type STRING.
LV_DISPLAYMODE = CONTROLLER->VIEW_GROUP_CONTEXT->IS_VIEW_IN_DISPLAY_MODE( CONTROLLER ).
%>
<thtmlb:areaFrameSetter toolbarButtons = "<%= controller->gt_button %>"
maxButtonNumber = "4"
displayMode = "<%= lv_displayMode %>"
/>
<chtmlb:config mode = "RUNTIME"
displayMode = "<%= CONTROLLER->VIEW_DISPLAY %>" />
7.创建DETAIL的事件处理器EDIT
METHOD EH_ONEDIT.
DATA:LR_COM TYPE REF TO ZL_ZLYTEST0_BSPWDCOMPONE3_IMPL. LR_COM ?= ME->COMP_CONTROLLER. CHECK LR_COM IS BOUND. IF LR_COM->DISPLAY = ABAP_TRUE.
LR_COM->DISPLAY = ABAP_FALSE.
VIEW_DISPLAY = ABAP_FALSE.
ELSE.
LR_COM->DISPLAY = ABAP_TRUE.
VIEW_DISPLAY = ABAP_TRUE.
ENDIF. ENDMETHOD.
OK了
