In the series of the SALV Simple Model, we will see how we can set the Display Settings to the entire ALV. You can find the previous discussions in this blog series at Tutorials > SALV Table Display
To set the display settings, we need to use the reference of the class CL_SALV_DISPLAY_SETTINGS. We will ask the reference of the Display settings from our ALV object created using the CL_SALV_TABLE. By using the display settings, we can set the Zebra style, Title of the ALV etc.
Here is the code snippet to which provides the ADD-ON code to our Base program. The base program can be found in the SALV Model 1: Normal ALV Table Display .
UML diagram for this example is like:

*$*$*.....CODE_ADD_1 - Begin..................................1..*$*$*
*
* In this section we will define the private methods which can
* be implemented to set the properties of the ALV and can be
* called in the
*
PRIVATE SECTION.
METHODS:
set_display_setting
CHANGING
co_alv TYPE REF TO cl_salv_table.
*$*$*.....CODE_ADD_1 - End....................................1..*$*$*

*$*$*.....CODE_ADD_2 - Begin..................................2..*$*$*
*
* In this area we will call the methods which will set the
* different properties to the ALV
CALL METHOD set_display_setting
CHANGING
co_alv = o_alv.
*$*$*.....CODE_ADD_2 - End....................................2..*$*$*
*
*$*$*.....CODE_ADD_3 - Begin..................................3..*$*$*
*
* In this area we will implement the methods which are defined in
* the class definition
*
METHOD set_display_setting.
*
DATA: lo_display TYPE REF TO cl_salv_display_settings.
*
* get display object
lo_display = co_alv->get_display_settings( ).
*
* set ZEBRA pattern
lo_display->set_striped_pattern( 'X' ).

* Title to ALV
lo_display->set_list_header( 'ALV Test for Display Settings' ).
