How can the ALV display more than 100 chars?

Hi,

I'm developing a ALV using ABAP Object, my problem is that I need that the ALV shows unless 1024 chars but it only shows 100.

I have the followind code to create the container and the ALV grid:

CREATE OBJECT v_o_container

EXPORTING

container_name = c_container

EXCEPTIONS

cntl_error = 1

cntl_system_error = 2

create_error = 3

lifetime_error = 4

lifetime_dynpro_dynpro_link = 5

OTHERS = 6.

CREATE OBJECT v_o_alvgrid

EXPORTING

i_parent = v_o_container

EXCEPTIONS

error_cntl_create = 1

error_cntl_init = 2

error_cntl_link = 3

error_dp_create = 4

OTHERS = 5.

CALL METHOD v_o_alvgrid->set_table_for_first_display

EXPORTING

i_structure_name = c_structure

is_layout = x_layout

CHANGING

it_outtab = i_alv_data

it_fieldcatalog = i_catalog

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

Could anyone, please, tell me if I need anymore to show more char?

Thank you very much.
