How to achieve Dynamic alv data in single docking container?

[former_member602948]

hi all,

i am a fresher in abap and i am trying to explore oops alv, now my requirement is i want to display multiple alv grid in a single docking container without using splitter container.

You can't. You need a separate container for each Grid. Have a look at the Easy_Splitter class - it's 'easy' to use!

yes this is also a way to achieve this requirement but my question is can i change the alv displayed in docking container dynamically based on user input?

[former_member182550]

Of course you can!

When you say 'Change' do you mean change the data or change the format and columns displayed ??

The answer to both is 'Yes'.

Why? Is it because you need to adjust the splitter "SASH" bar depending on the number of lines in the first ALV, or is it just that you don't know how to define a splitter container inside a docking container?

as i said i am trying to explore. my question is can i modify the alv in docking container based on user input i.e the alv should get replaced with the present one.

yes you can

but how? how can i switch between 2 alv grids based on user input from main alv?

[Sandra_Rossi]

For instance, just free the main alv, and instantiate a new alv. What did you try?

thanks for this suggestion, now its working my data is changed dynamically but while switching between 2 alv grids i am getting dump because i am freeing the previous alv so it is not getting the reference object for it.

if grid_inst is not INITIAL.

call method grid_inst->free.

endif.

IF grid_bp is not INITIAL.

call method grid_bp->free.

ENDIF.

To switch between 2 alv grids based on user input from main alv, for instance you may free the main alv, and instantiate a new alv.

Remember that if you call the method FREE, the control variable is still instantiated, only the GUI control is freed, so to avoid subsequent CNTL_ERROR short dumps, it's easier to set the control variable to initial (CLEAR/FREE), so that both the control variable and the GUI control are "synchronized", and to check whether the GUI control is present, you may simply test IF control_variable IS BOUND.

If you don't CLEAR/FREE the control variable, another possibility is : if control_variable->is_alive( ) <> cl_gui_control=>state_dead.
