Hi Bala,

Its possible. Just go to the action handler for the button & read the attribute ID of the WDEVENT which is passed by the framework. This id will contain the id of the button which triggered the event. Consider the code fragment below:

method ONACTIONACTION .
    DATA:  lv_button_name type string.
    lv_button_name = wdevent->get_string( name = 'ID' ).
endmethod.

At the end of execution lv_button_name will have the ID of the button which triggered the event.

Use WDEVENT which is used to capture the UI element events that you have created on the View.

data l_button_name type string.

l_button_name = wdevent->get_string( name = 'ID' ).

case l_button_name.

when u2018button1u2019.

<Code>

when ' button2'.

<Code>

endcase

using above , u will able to fetch the Button ID.
