HI,

Use a class and handler method as given below

CLASS lcl_event_receiver DEFINITION.

PUBLIC SECTION.

METHODS:

handle_double_click

FOR EVENT double_click OF cl_gui_alv_grid

IMPORTING e_row e_column.

METHODS: handle_button_click

FOR EVENT button_click OF cl_gui_alv_grid

IMPORTING es_col_id es_row_no.

ENDCLASS. "LCL_EVENT_RECEIVER DEFINITION

CLASS lcl_event_receiver IMPLEMENTATION.

METHOD handle_double_click.

READ TABLE itab INDEX e_row-index INTO w_string.

write the code what u want to execute.

ENDMETHOD. "HANDLE_DOUBLE_CLICK

after this u have to set handler for the double click event to get triggered.

u can write it like this.

create a object of the above class and set the handler.

data: w_event_receiver type ref to lcl_event_receiver.

CREATE OBJECT w_event_receiver.

SET HANDLER w_event_receiver->handle_double_click FOR w_grid.

Hi gray,

For coloring the whole row,

in the internal table add another field

color(4) type c.

data: g_col(4) type c.

l_char type c.

loop at itab into wa where condition.

ind = sy-tabix.

l_char = cl_gui_resources=>list_col_negative.

CONCATENATE 'C' " = constant

l_char "color

'0' "intensified 0=off 1=on

'0' "inverse 0=off 1=on

INTO g_col.

ITAB-color = g_col.

modify itab from wa index ind

transporting color.

endloop.

and in the layout field add this.

data: layout type lvc_s_layo.

layout- info_fname = 'COLOR'.

and pass it to the display the table in alv container.

and for implementing double click whenever the row is colored use this condition.

CLASS lcl_event_receiver IMPLEMENTATION.

METHOD handle_double_click.

READ TABLE itab into wa_itab INDEX e_row-index INTO w_string.

if wa_itab-color = 'C300'.

write the code for double click.

endif.

ENDMETHOD. "HANDLE_DOUBLE_CLICK

ENDCLASS. "lcl_event_receiver IMPLEMENTATION
