ALV problem

[former_member734916]

Hello All,

I need the solutions for the following.

In the ALV output I am displaying a checkbox in edit mode, but I want this checkbox in edit mode for some records and disable mode for some other records depending on a condition.

Ex.

ITAB. Output fields.

Checkbox F1 F2

if the value of the field F1 = 'V' that checkbox should be in edit mode that means we can check or uncheck.

if the value of the field F1 = 'S' that checkbox should be in disable mode.

points assured.

Regards.

Krishna.

hi,

to make editable and not editable some cells you have to do the following modification to your code:

1 - extend the structure of your table with one more filed

>data: begin of outtab occurs 0,

> Checkbox type xfeld

> F1(1),

> ...

> style TYPE lvc_t_styl,

> end of outtab.

2 - set value 'STYLE' into the field stylefname of strucure typed lvc_s_layo.

>data: ls_layo type lvc_s_layo.

>lvc_s_layo-stylefname = 'STYLE'.

3 - in the fieldcatlog set editable the Checkbox

4 - loop to your internal table outtab and set the style of evry single cell

>data: ls_style type lvc_s_styl.

>loop at outtab.

>if outtab-F1 = 'S'.

>ls_style-fieldname = 'CHECKBOX'.

>ls_style-style = cl_gui_alv_grid=>mc_style_disabled.

>append ls_style to outtab-style.

>clear ls_style.

>else.

>clear outtab-style.

>endif.

>modify outtab.

>endloop.

5 - disply ALV.

Hello Marco,

Thanks for your answer.

I did the all changes in my code as suggested by you still it is not working properly, can you see the below code and tell me still I am missing anything.

type-pools : slis.

DATA: l_f_repid LIKE sy-repid.

DATA: l_t_fieldcat TYPE slis_t_fieldcat_alv,

l_r_fieldcat LIKE LINE OF l_t_fieldcat.

class cl_gui_alv_grid definition load.

*output tab

data : begin of itab occurs 0,

cb,

f1,

f2(10),

style TYPE lvc_t_styl,

end of itab.

data: ls_style type lvc_s_styl.

data: ls_layo type lvc_s_layo.

ls_layo-stylefname = 'STYLE'.

itab-f1 = 'S'.

itab-f2 = 'Test'.

append itab.

clear itab.

itab-f1 = 'V'.

itab-f2 = 'Test1'.

append itab.

clear itab.

itab-f1 = 'S'.

itab-f2 = 'Test2'.

append itab.

clear itab.

l_r_fieldcat-col_pos = 1.

l_r_fieldcat-tabname = 'ITAB'.

l_r_fieldcat-fieldname = 'CB'.

l_r_fieldcat-checkbox = 'X'.

l_r_fieldcat-edit = 'X'.

append l_r_fieldcat to l_t_fieldcat .

clear l_r_fieldcat.

l_r_fieldcat-col_pos = 2.

l_r_fieldcat-tabname = 'ITAB'.

l_r_fieldcat-fieldname = 'F1'.

append l_r_fieldcat to l_t_fieldcat .

clear l_r_fieldcat.

l_r_fieldcat-col_pos = 3.

l_r_fieldcat-tabname = 'ITAB'.

l_r_fieldcat-fieldname = 'F2'.

append l_r_fieldcat to l_t_fieldcat .

clear l_r_fieldcat.

loop at itab.

if itab-f1 = 'S'.

ls_style-fieldname = 'CB'.

ls_style-style = cl_gui_alv_grid=>mc_style_button .

ls_style-style = cl_gui_alv_grid=>mc_style_disabled.

append ls_style to itab-style.

clear ls_style.

else.

clear itab-style.

endif.

modify itab.

endloop.

l_f_repid = sy-repid.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM = l_f_repid

IT_FIELDCAT = l_t_fieldcat

TABLES

t_outtab = itab .

you have forgotten to pass the structure layout to the function REUSE_ALV_GRID_DISPLAY.
