Tree ALV

[Former Member]

Hi,

How can I refresh the Tree alv grid to display the modified data in the internal table. I have gone through cl_gui_alv_tree=>refresh_table_display method but as the refresh method is private in this class interface i am not able to use it. Is there any other method to refresh my tree grid.

Thanks in Advance.

Laxmi,

Try using the FRONTEND_UPDATE method.

This method is implemented in CL_ALV_TREE_BASE which is the super class / parent of CL_GUI_ALV_TREE.

Hi,

In SE38 give BCALV*,

press F4,

you will get a list of demo programs for ALV grid and ALV Tree.

You can check the demo programs.

You can also try the flush method with will remove everything and then use the create.

call method cl_gui_cfw=>flush.

Hi !

If you want so send the complete table again you can

simply use

CALL METHOD ref_alv_grid->set_table_for_first_display

To bouid up a new, and refreshed ALV-Grid display.

But be shure not to create the ref_alv_grif obcent again !

If you want so save the line the user selected you can use the method:

CALL METHOD ref_alv_grid->get_selected_rows

to save it and

CALL METHOD ref_alv_grid->set_selected_rows

to set it again auf displaying the "new" ALV-Grid.

Hi,

you need to call the method <b>frontend_update</b> to update your tree control, it will behave like a refresh.

 call method g_alv_tree->frontend_update.
