Hi

Why dont you directly call the method from patterns button in SE38. Dont create a reference .

In pattern -> choose ABAP Object patterns.

Then give class -> CL_GUI_ALV_GRID and method SET_TABLE_FOR_FIRST_DISPLAY .

or if you want to create a new refernce to class in your program try this -

<b>data: grid_custom_container TYPE REF TO cl_gui_custom_container,

grid_container TYPE scrfname VALUE 'MYGRID',

alv_grid tYPE REF TO cl_gui_alv_grid.

CREATE OBJECT grid_custom_container

EXPORTING container_name = grid_container.

CREATE OBJECT alv_grid

EXPORTING i_parent = grid_custom_container.</b>

Cheers.

You have to replace 'me' to 'alv_grid'.

[athavanraja]

in the pattern wizard

pass the <b>instance</b> name (instance of the alv_grid) if you leave it blank system will use <b>me</b> and you have to manually change that.
