How to access an ALV by clicking button

[former_member224404]

Hi team,

I have created a ALV display (by using SALV_WD_TABLE component usage) in wddoinit method of my view.Now I have a button.If I click on button,one of the field of ALV would be hidden.

Now I know how to hidden the field but I don't know the way to access my ALV inside the onclick method of the button.

Waiting for your help...

Thanks,

Mainak

Hi Mainak,

You can use this code to get access to your alv

DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .

l_ref_interfacecontroller = wd_this->wd_cpifc_alv( ).

DATA: l_value TYPE REF TO cl_salv_wd_config_table.

l_value = l_ref_interfacecontroller->get_model( ).

Hi , You can do it by following way .

• create an instance of ALV component

DATA:

lr_salv_wd_table_usage TYPE REF TO if_wd_component_usage.

lr_salv_wd_table_usage = wd_this->wd_cpuse_alv( ).

IF lr_salv_wd_table_usage->has_active_component( ) IS INITIAL.

lr_salv_wd_table_usage->create_component( ).

ENDIF.

<b>* hide field CURR_ISO</b> DATA:

lr_column_settings TYPE REF TO if_salv_wd_column_settings,

lr_column TYPE REF TO cl_salv_wd_column.

lr_column_settings ?= wd_this->alv_config_table.

<b><i>lr_column = lr_column_settings->get_column( 'CURR_ISO' ).

lr_column->set_visible( if_wdl_core=>visibility_none ).</i></b>

I have another idea but not have tried it .This Set_Visible parameter is Boolean . So make same boolean node and change its value onclick and send its value as parameter to Set Visible.
