一、单元格定义为按钮：
1、 ALV内表中首先在显示数据内表中插入类型为LVC_T_STYL的内表。
即增加一个字段CELLSTYLES TYPE LVC_T_STYL。
2、 将单元格设置为按钮：(eg：字段ZDISPLAY设置为按钮)
DATA: LV_STYLEROW TYPELVC_S_STYL.
LOOP AT ITAB_ALVDATA INTO WA_ALVDATA.
“ITAB_ALVDATA为ALV内表
LV_STYLEROW-FIELDNAME ='ZDISPLAY'.
LV_STYLEROW-STYLE. = CL_GUI_ALV_GRID=>MC_STYLE_BUTTON.
APPENDLV_STYLEROWTOWA_ALVDATA-CELLSTYLES.
ENDLOOP.
3、 在layout structure中指明显示数据内表中表示样式的字段。
GV_LAYOUT-STYLEFNAME ='CELLSTYLES'.
二、按钮事件的触发调用
如果是用OO方式调用的ALV，那么很简单，只需要对对象注册事件即可，这类的资料也很多，但是对于CALL FUNCTION方式调用的ALV来说，我们可以用下列方法来处理。
1、 建事件CLASS
添加BUTTON_CLICK事件
CLASSLCL_EVENT_RECEIVERDEFINITION.
PUBLICSECTION.
METHODS:
HANDLE_BUTTON_CLICK
FOREVENTBUTTON_CLICKOFCL_GUI_ALV_GRID
IMPORTINGES_COL_ID ES_ROW_NO,
ENDCLASS.
CLASSLCL_EVENT_RECEIVERIMPLEMENTATION.
METHODHANDLE_BUTTON_CLICK.
PERFORMBUTTON_CLICKUSINGES_COL_ID ES_ROW_NO.
ENDMETHOD.
ENDCLASS.
DATAGV_EVENT_RECEIVERTYPEREFTOLCL_EVENT_RECEIVER.
2、 设置ALV的EVENT事件(caller_exit)
FORMFM_EVENT_BUILD.
DATALV_EVENTLIKELINEOFGV_EVENTS.
CALLFUNCTION'REUSE_ALV_EVENTS_GET'
EXPORTING
I_LIST_TYPE =0
IMPORTING
ET_EVENTS = GV_EVENTS
EXCEPTIONS
LIST_TYPE_WRONG =1
OTHERS =2
.
IFSY-SUBRC <>0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
LV_EVENT-NAME ='CALLER_EXIT'.
LV_EVENT-FORM='FM_BUTTON'.
APPENDLV_EVENTTOGV_EVENTS.
ENDFORM.
3、 在上面caller_exit定义的FORM.:'FM_BUTTON'里通过函数‘GET_GLOBALS_FROM_SLVC_FULLSCR’得到ALV的GRID对象,再设置这个GRID的BUTTON_CLICK事件。
DATAGV_GRIDTYPEREFTOCL_GUI_ALV_GRID.
FORMFM_BUTTONUSINGE_GRIDTYPESLIS_DATA_CALLER_EXIT.
CALLFUNCTION'GET_GLOBALS_FROM_SLVC_FULLSCR'
* EXPORTING
* IR_SALV_FULLSCREEN_ADAPTER =
IMPORTING
* ET_EXCLUDING =
* E_REPID =
* E_CALLBACK_PROGRAM =
* E_CALLBACK_ROUTINE =
E_GRID = GV_GRID
* ET_FIELDCAT_LVC =
* ER_TRACE =
* E_FLG_NO_HTML =
* ES_LAYOUT_KKBLO =
* ES_SEL_HIDE =
* ET_EVENT_EXIT =
* ER_FORM_TOL =
* ER_FORM_EOL =
.
CREATEOBJECTGV_EVENT_RECEIVER.
SETHANDLERGV_EVENT_RECEIVER->HANDLE_BUTTON_CLICKFORGV_GRID.
ENDFORM.
4、 在CLASS中定义的BUTTON_CLICK事件的FORM：BUTTON_CLICK中写需要单击按钮后完成的处理。
FORMBUTTON_CLICKUSINGP_COL_ID
P_ROW_NOTYPElvc_s_roid.
READTABLEITAB_ALVDATAINTOWA_ALVDATAINDEXP_ROW_NO-ROW_ID.
PERFORMFM_DISPLAY_COMMENT.
ENDFORM.
5、 DISPLAY ALV
PERFORMFM_EVENT_BUILD.
* Call ALV Funcation
CALLFUNCTION'REUSE_ALV_GRID_DISPLAY_LVC'
EXPORTING
I_CALLBACK_PROGRAM = SY-REPID
I_GRID_TITLE = GV_TITLE
I_DEFAULT ='X'
I_SAVE ='A'
IT_EVENTS = GV_EVENTS
IT_FIELDCAT_LVC = GV_FIELDCAT_ALV[]
IS_LAYOUT_LVC = GV_LAYOUT
I_CALLBACK_PF_STATUS_SET = GV_STATUS
I_CALLBACK_USER_COMMAND ='USER_COMMAND'
TABLES
T_OUTTAB = ITAB_ALVDATA
EXCEPTIONS
PROGRAM_ERROR =1
OTHERS =2.
