Hi,

In REUSE_ALV_GRID_DISPLAY, you have a parameter

TOP_OF_PAGE, pass your top-of-page sub routine to this parameter,

& add it in your events table as well.

hope this helps you.

This is an example for docking container u have to split the container and in one part u will be dispalying TOP-OF_pAGE in the other the grid.

Hi,

i have to use Top_of_page event, is it necessary to use Split and docking container for this ? please help me on this, i need it urgently.

Nilanjana

Hi Nilanjana,

Its not mandatory to use split or docking container for using the TOP_OF_PAGE. You can use two separate containers

in the screen for the purpose. But its preferable to use docking or splitting container as the buffer space reqd is

considerably low compared to placing two differebnt containers on screen.

You can use the class CL_DD_DOCUMENT for having TOP_OF_PAGE in ABAP OO. In order to trigger the TOP_OF_PAGE event

the method LIST_PROCESSING_EVENTS of the class CL_GUI_ALV_GRID must be called. And in the event handler method you

have to build the TOP_OF_PAGE using the different methods available in the class CL_DD_DOCUMENT (for example the

method ADD_TEXT is used to add text to the TOP_OF_PAGE).

Thanks and Regards,

Hi,

Top-Of-Page is only tiggered while u display GRID output as a list or u r printing the report.

In OOPS , u have to use Event handler for class "cl_gui_alv_grid" and event name is "print_top_of_page".

The following function is called from top of page

FORM TOP_OF_PAGE.

CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'

EXPORTING

I_LOGO = 'ENJOYSAP_LOGO'

IT_LIST_COMMENTARY = SD_HEADING.

ENDFORM. "TOP_OF_PAGE

Hi venkateswarao g...,

the blog Ravi mentions is exactly what you need.

Only in Full screen mode (as used by FM REUSE_ALV_GRID_DISPLAY) the grid will use it's own screen and create the required containers for TOP, grid and bottom area.

If you use your own container, you have to put a splitter container into it using the first row for top-of-page and the second row for the grid itself.

Think about this and then read the blog posted by Vijay Babu Dudla - it is much easier than it looks.

Clemens
