hi,

I can give example for one of the ALV action 'ON_FUNCTIONu2019.The one i marked in bold will help achieving your requirement.

I have used the standard component u2018salv_wd_tableu2019 in my application and will be able to give example by adding a button named 'NEW__BUTTON' .

In the WDDOINIT method of the component controller, use the following code to define column name, your own buttons, visible column for the same component usage.

DATA:

lr_salv_wd_table_usage TYPE REF TO if_wd_component_usage,

lr_salv_wd_table TYPE REF TO iwci_salv_wd_table.

*Check ALV 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( ).

ELSE.

lr_salv_wd_table_usage->delete_component( ).

lr_salv_wd_table_usage->create_component( ).

ENDIF.

*Get ALV component

lr_salv_wd_table = wd_this->wd_cpifc_alv( ).

wd_this->mr_table type ref to CL_SALV_WD_CONFIG_TABLE.

*Get ConfigurationModel from ALV Component

wd_this->mr_table = lr_salv_wd_table->get_model( ).

*Set table settings

DATA:

lr_table_settings TYPE REF TO if_salv_wd_table_settings.

lr_table_settings ?= wd_this->mr_table .

lr_table_settings->set_visible_row_count( '5' ).

lr_table_settings->set_width( '100%' ).

DATA:

lr_header TYPE REF TO cl_salv_wd_header,

l_header_text TYPE string.

lr_header = lr_table_settings->get_header( ).

l_header_text = cl_wd_utilities=>get_otr_text_by_alias( 'NEW__BUTTON' ).

lr_header->set_text( l_header_text ).

lr_header->set_tooltip( l_header_text ).

"lr_table_settings->set_selection_mode( cl_wd_table=>e_selection_mode-multi_no_lead ).

*Set functions

IF wd_this->mb_no_maintain NE abap_true.

DATA:

lr_function TYPE REF TO cl_salv_wd_function,

lr_fe_button TYPE REF TO cl_salv_wd_fe_button,

l_btn_text TYPE string.

*Add the button here for validation on the top of the ALV

*This is where you add the buttons on the same ROW.

lr_function = lr_functions->create_function( 'NEW__BUTTON' ).

CREATE OBJECT lr_fe_button.

l_btn_text = cl_wd_utilities=>get_otr_text_by_alias( 'NEW__BUTTON' ).

lr_fe_button->set_text( l_btn_text ).

lr_fe_button->set_tooltip( l_btn_text ).

lr_function->set_editor( lr_fe_button ).

After defining the buttons 'NEW__BUTTON' , handle the actions for the same using the method u2018LIST_ACTIONu2019 which should have the event as u2018ON_FUNCTIONu2019, controller as u2018interface controlleru2019 and component use as the name you have given say u2018ALVu2019.

In the method u2018LIST_ACTIONu2019, handle the actions as below. This method will have the following importing parameters.

WDEVENT Importing CL_WD_CUSTOM_EVENT

R_PARAM Importing IF_SALV_WD_TABLE_FUNCTION

method list_action .

case r_param->id .

when 'NEW__BUTTON'.

"Do the validation here-"

endcase.

endmethod.

Thanks,

The Events of inner UI elements are not exposed directly as they normally would be if they were standalone. Generally you can capture them using either the

ON_DATA_CHECK:

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/c8/6c80dbedfe42d1a93f8e6df1d7244a/frameset.htm

This gets trigger for any press of ENTER, so it generally works like the Input Field onEnter.

You could also consider ON_CELL_ACTION:

http://help.sap.com/saphelp_nw70ehp1/helpdata/en/45/12093591152464e10000000a1553f7/frameset.htm

It is a higher level Event that encompasses both ON_DATA_CHECK and ON_CLICK.

hi thomas,

As i mentioned above i tryed all

the events. in ALV .

on_function

on_lead_select and all

its working.

i have ALV table with to field two inputfield

Ex :a1 and a2 fields

if i enter the value in a1 and a2 . And give Enter.

a1 and a2 should print. in Message area.

Thankx

Vivek

[thomas_jung]

I'm not sure I understand what you are saying. If you use the ON_DATA_CHECK, an event will get fired when the user presses ENTER. Are you saying, that you aren't getting this event?

[vivekananthan_sellavel]

hi;

yes, I used On_data_check and i tried but that event is not geeting fired .

Pls give suggestion .

Thanks and Regards

Vivakananthan S.

[thomas_jung]

Did you use IF_SALV_WD_TABLE_SETTINGS~SET_DATA_CHECK to control when the DATA Check event gets fired as stated in the online help link?

You are going to want to change it to IF_SALV_WD_C_TABLE_SETTINGS~DATA_CHECK_ON_CELL_EVENT
