How to use Style in LVC_S_LAYO (ALV Grid Layout)

Question

Hi Experts,
I am trying to set field 'STYLEFNAME' of LVC_S_LAYO while setting up layout for ALV GRID using 'SET_TABLE_FOR_FIRST_DISPLAY' . I'm passing the field name contain the styles for each row. I am setting it in the same way we set 'INFO_FNAME' by passing color field name for coloring the rows. Styles are available in include <CL_ALV_CONTROL> .
Please note styles are working properly when I am setting it at field cat level by setting fieldcat field LVC_S_FCAT-STYLE. But set sets style for entire column. I want to set style for few rows. I want to use style 'ALV_STYLE_BUTTON' .
Please advice how to do this.
Regards,
Sushant.

I'll try to understand your question.
You have a 'new-style' alv and want to show some fields as pushbutton.
To make a cell to be displayed as a pushbutton, we have two steps.
Firstly, insert a new inner table of type u201CLVC_T_STYLu201D into your list data table.
*--- Internal table holding list data
DATA BEGIN OF gt_list OCCURS 0 .
INCLUDE STRUCTURE SFLIGHT .
DATA rowcolor(4) TYPE c .
DATA cellcolors TYPE lvc_t_scol .
DATA carrid_handle TYPE int4 .
DATA connid_handle TYPE int4 .
DATA cellstyles TYPE lvc_t_styl .
DATA END OF gt_list .
Fill this inner table for each field to be displayed as pushbutton.
DATA ls_style TYPE lvc_s_styl .
READ TABLE gt_list INDEX 7 .
ls_style-fieldname = 'SEATSMAX' .
ls_style-style = cl_gui_alv_grid=>mc_style_button .
APPEND ls_style TO gt_list-cellstyles .
MODIFY gt_list INDEX 7 .
As usual, we state our list data table field related with styles in the layout structure at field u2018STYLEFNAMEu2019.
e.g. ps_layout-stylefname = 'CELLSTYLES' .
Button click event is handled like hotspot click via the event u201Cbutton_clicku201D through its parameters u201Ces_col_idu201D and u201Ces_row_nou201D which contain the address of the clicked pushbutton cell.
