ALV OO中右擊顯示列進行隱藏列處理，但是右擊后發現無效，該如何處理？

其實問題出在創建“ALV?grid?container”?這里。

問題代碼：

"Create ALV grid containerPERFORM CREATE_GRID_CONTAINER USING GV_CONT_BODY GV_GRID ABAP_TRUE.*&---------------------------------------------------------------------* *& Form create_grid_container *&---------------------------------------------------------------------* * text *----------------------------------------------------------------------* * -->P_PARENT text * -->PO_GRID text * -->P_APPL text *----------------------------------------------------------------------* FORM CREATE_GRID_CONTAINER USING P_PARENTPO_GRID_BODY TYPE REF TO LCL_ALV_GRIDP_APPL.CHECK PO_GRID_BODY IS INITIAL.CREATE OBJECT PO_GRID_BODYEXPORTINGI_PARENT = P_PARENTI_APPL_EVENTS = P_APPL. ENDFORM. " CREATE_GRID_CONTAINER

在生成CL_GUI_ALV_GRID實例時，構造器參數I_PARENT是必需的，這一點毋庸置疑的，但這里對I_APPL_EVENTS賦值為X，則不會按照系統的標準來執行，即要對ALV 的功能進行擴展。

• 'X'?->?APP?EVENT
• ' '?->?SYSTEM?EVENT

修正代碼：

"Create ALV grid containerPERFORM CREATE_GRID_CONTAINER USING GV_CONT_BODY GV_GRID ABAP_TRUE. *&---------------------------------------------------------------------* *& Form create_grid_container *&---------------------------------------------------------------------* * text *----------------------------------------------------------------------* * -->P_PARENT text * -->PO_GRID text * -->P_APPL text *----------------------------------------------------------------------* FORM CREATE_GRID_CONTAINER USING P_PARENTPO_GRID_BODY TYPE REF TO LCL_ALV_GRIDP_APPL.CHECK PO_GRID_BODY IS INITIAL.CREATE OBJECT PO_GRID_BODYEXPORTINGI_PARENT = P_PARENTEXCEPTIONSERROR_CNTL_CREATE = 1ERROR_CNTL_INIT = 2ERROR_CNTL_LINK = 3ERROR_DP_CREATE = 4OTHERS = 5.ENDFORM. " CREATE_GRID_CONTAINER
