A question about ALV

Question

Hi, everybody.
I'm developing a dynpro which showing a table on screen.
I use a CL_GUI_ALV_GRID to realize the table.
But now, I meet a problem, we want to keep some rows uneditable, and still allow other rows be editable.
I know how to set a column (un)editable in ALV, but how to do with a row case?
Any suggestion and solution is welcome.
Thanks a lot.

Hello,
In order to make individual Cells (i. e. rows, not whole columns) editable,  you need to
1) Add a field of type LVC_T_STYL to the structure of your table (in this example, lets say you have named the table variable it_list). The type LVC_T_STYL is a table type, so this way you will add an "inner table" to your table. For this example, I will call this inner table "CELLSTYLES".
2) In this inner table you can add individual styles for each cell of the current line. To make single cells editable, you utilize code like this:
data: wa_cellstyle type lvc_t_styl.
loop at it_list into wa_list.
if <place conditional logic here>.
    wa_cellstyle-fieldname = '<Name of editable cell>'.
    wa_cellstyle-style = cl_gui_alv_grid=>mc_style_enabled.
    insert wa_cellstyle into wa_list-cellstyles.
  endif.
  modify it_list from wa_list.
endloop.
I have put together this "from scratch", as I dont have acces to a system right now, so you might have to make some changes, but the general outline of it should be clear...
Hope this helps,
Joerg
