You have to create a object for custom container for the class cl_gui_custom_container.Then you have to give the i_parent for the ALV class object as <custom container object>

create object <custom container>

create object <alv grid>

importing i_parent = <custom container>.

Hi,

You should use custom container or docking container to hold the grid.

You need to create objects for the same.

Check standard demo programs bc_alv.You will understand better.
