WDA: ALV: action for buttons, links and message class

[Former Member]

Hello,

I am using ALV and need to create few buttons on a tool bar.

I can create a button:

data: create_new_button TYPE REF TO cl_salv_wd_fe_button.

CREATE OBJECT create_new_button.

create_new_button->set_text( 'Create New' ).

create_new_button->set_image_source( value = 'ICON_CREATE' ).

Now I need to attach an action to this button. The button is created in INIT method of a component controller

Action is defined in a view. How can I map this?

Also, I have a message class and instead of passing 'Create New' to set_text method how can I get a message from my message class and pass it to set_text method?

Another action that I need to assign to a link that is in one of the columns of the ALV. How can this be done?

Thanks.

Hi Georgy

Here is an article on how to create UI elements in ALV toolbar and how to catch their events.

Hi, I don't know if you need the information anymore, but here is one solution:

At first you have to create a function with:

DATA:

lr_function TYPE REF TO cl_salv_wd_function,

l_value TYPE REF TO cl_salv_wd_config_table.

lr_function = l_value->if_salv_wd_function_settings~create_function( id = 'NAMEOFFUNCTION' ).

Second create the Object ('create_new_button') like you did it.

Third assign the toolbar element to the function.

lr_function->set_editor( create_new_button ).

Now you have to create a event handler method in the view with event ON_FUNCTION of your ALV component. In this method you can catch the event triggered by your button and set your code.

I hope it helps.
