ALV size should be adjustable to screen resolution automatically

Question

Hi,
Is there in any way that the size of ALV grid should be adjustable to screen resolution automatically?
Thanks & Regards,

Hello Reena
If your ALV list is the only element on your dynpro then you should not use a custom container on the dynpro. Instead use the following approach:
*& Report  ZUS_SDN_ALVLIST_FULLSCREEN
REPORT  zus_sdn_alvlist_fullscreen.
DATA:
  gt_kna1           TYPE STANDARD TABLE OF kna1.
DATA:
  go_docking        TYPE REF TO cl_gui_docking_container,
  go_alvgrid        TYPE REF TO cl_gui_alv_grid.
START-OF-SELECTION.
* Select some data
  SELECT * FROM  kna1 INTO TABLE gt_kna1.
* Create docking container and dock at left side
  CREATE OBJECT go_docking
    EXPORTING
