How to change layout dynamically?

[Former Member]

Hi,

I have 15 fields in my WD ALV output. All i need is to display only certain columns on some action (by hitting button1) and to display other set of columns on other action (by hitting button2). Please let me know how should i approach in this?

Hello

In ALV, YOU BIND THE TABLE, SO all what you binding will be displayed.

In the Action, Get the context, Check which all attributes you want to display, Bind them to context table.

It will show only those.

Hello

In ALV there is already a view option is there, Where user can select which columns he want to see and which to hide.

User can save views based on its requirement and switch when ever required.

Other wise, You have to get the attributes and set them dynmically.

Via the ALV Model API classes you can access all the current columns and then hide any of them you wish. Here is some sample code:

DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
  l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
  ENDIF.

  DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
  l_salv_wd_table = wd_this->wd_cpifc_alv( ).
  DATA l_table TYPE REF TO cl_salv_wd_config_table.
  l_table = l_salv_wd_table->get_model( ).

 DATA l_column TYPE REF TO cl_salv_wd_column.
  l_column = l_table->if_salv_wd_column_settings~get_column( 'CLIENT' ).
  l_column->set_visible( cl_wd_uielement=>e_visible-none ).

There is also a GET_COLUMNS method that will return an internal table of all columns and their objects that you can loop through.
