使用REUSE_ALV_GRID_DISPLAY_LVC显示ALV时,如何将列、行或者具体的某个单元格设置成可编辑能输入状态?这个其实很简单,下面一一讲解:
1, 列可编辑
只要将catalog中的字段edit设置成‘X‘,整列就变成能输入的了,LVC_S_FCAT-EDIT
代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 |
REPORT ztest_alv_lvc_edit. TYPES:BEGIN OF gty_ekko, ebeln TYPE ekko-ebeln, verkf TYPE ekko-verkf, END OF gty_ekko. DATA:git_ekko TYPE STANDARD TABLE OF gty_ekko. DATA:git_fcat TYPE lvc_t_fcat, gwa_fcat LIKE LINE OF git_fcat, gwa_layout TYPE lvc_s_layo. DATA:l_pos TYPE i VALUE 1. START-OF-SELECTION. SELECT ebeln verkf INTO TABLE git_ekko FROM ekko UP TO 10 ROWS. CLEAR: l_pos. l_pos = l_pos + 1. gwa_fcat-coltext = ‘PO‘. gwa_fcat-scrtext_l = ‘PO‘. gwa_fcat-scrtext_m = ‘PO‘. gwa_fcat-scrtext_s = ‘PO‘. gwa_fcat-fieldname = ‘EBELN‘. gwa_fcat-col_pos = l_pos. gwa_fcat-outputlen = ‘10‘. APPEND gwa_fcat TO git_fcat. l_pos = l_pos + 1. gwa_fcat-coltext = ‘PO item‘. gwa_fcat-scrtext_l = ‘PO item‘. gwa_fcat-scrtext_m = ‘PO item‘. gwa_fcat-scrtext_s = ‘PO item‘. gwa_fcat-fieldname = ‘VERKF‘. gwa_fcat-col_pos = l_pos. gwa_fcat-edit = ‘X‘. "设置列为可编辑状态 gwa_fcat-outputlen = ‘20‘. APPEND gwa_fcat TO git_fcat. gwa_layout-zebra = ‘X‘. gwa_layout-sel_mode = ‘A‘. gwa_layout-cwidth_opt = ‘X‘. CALL FUNCTION ‘REUSE_ALV_GRID_DISPLAY_LVC‘ EXPORTING i_callback_program = sy-repid is_layout_lvc = gwa_layout it_fieldcat_lvc = git_fcat TABLES t_outtab = git_ekko[] EXCEPTIONS program_error = 1 OTHERS = 2. IF sy-subrc = 0. * BREAK-POINT. ENDIF. |
运行结果:
2, 整个ALV可编辑
将layout中的EDIT字段赋值’X‘(LVC_S_LAYO-EDIT),就可以将整个ALV设置成可输入状态。
还有一种比较笨的办法就是将所有列都设置成可输入。
代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
gwa_layout-zebra = ‘X‘. gwa_layout-sel_mode = ‘A‘. gwa_layout-cwidth_opt = ‘X‘. gwa_layout-edit = ‘X‘. "将整个ALV设置成可编辑 gwa_glay-edt_cll_cb = ‘X‘. CALL FUNCTION ‘REUSE_ALV_GRID_DISPLAY_LVC‘ EXPORTING i_callback_program = sy-repid is_layout_lvc = gwa_layout it_fieldcat_lvc = git_fcat * i_grid_settings = gwa_glay TABLES t_outtab = git_ekko[] EXCEPTIONS program_error = 1 OTHERS = 2. |
3, 单元格可编辑
如果要让单元格变成可输入,需要在alv输出内表中多定义一个保存单元格style的字段(类型:lvc_t_styl ),然后填入style属性(可编辑或者是不可编辑),最后还要在layout-stylefname中指定style的字段名。
代码如下:将EBELN设置成不可输入。
1 2 3 4 5 |
TYPES:BEGIN OF gty_ekko, ebeln TYPE ekko-ebeln, verkf TYPE ekko-verkf, style TYPE lvc_t_styl, "将该字段设置为保存编辑状态的字段 END OF gty_ekko. |
1 2 3 |
gwa_edit-fieldname = ‘EBELN‘. gwa_edit-style = cl_gui_alv_grid=>mc_style_disabled."设置为不可输入 INSERT gwa_edit INTO TABLE git_edit. |
1 |
gwa_layout-stylefname = ‘STYLE‘. "指定保存编辑状态的字段名 |
style属性可以在类CL_GUI_ALV_GRID中可以找到:
MC_STYLE_DISABLED:禁止输入
MC_STYLE_ENABLED:可编辑,可输入。
需要注意的是:MC_STYLE_ENABLED输入性不能单独使用,一定在EDIT = ‘X‘(layout-edit 或者是catalog-edit)的场合下,才可以利用MC_STYLE_ENABLED进行不可编辑到编辑切换,也就是不设置edit = ‘X‘,MC_STYLE_ENABLED是不起作用的。

4, 行可编辑
类似于单元格可编辑,只要将一行之外的所有行都变成不可输入,也就实现了行可编辑。逻辑如下:
1,通过layout-edit = ’X‘ 将整个行项目都变成可输入
2,将某行之外的所有行style设置成 cl_gui_alv_grid=>mc_style_disabled.
代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 |
