need method to disable checkbox

Hi,

My alv Grid report contains checkbox at end of each row, when ever user select the checkbox , I am taking the particular line to internal Table by using below code.

DATA cl_gui_alv_grid TYPE REF TO cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = cl_gui_alv_grid.

CALL METHOD cl_gui_alv_grid->check_changed_data.

My problem is whenever user selects the checkbox the checkbox should go Gray(Disabled).

Is there any method to do this, If so pls give sample code.

I tried with SET_VISIBLE, but not working

I am using version 4.6C

Thanks

kar
