Hi Kumar,
This is the approach suggested by SAP. Whenever you want to modify any particular property of an ui element we need to have it bound to some context attribute & we modify the value of this context attribute. We can even do it using dynamic programming but this way we would end up changing the ui elements properties in a method other than the WDDOMODIFYVIEW which is strongly not suggested. However am just giving you the methodology & code for the dynamic programming approach code just for your understanding:
1) Fetch the reference of your tabstrip by passing its ID within your WDDOMODIFYVIEW
2) Save the reference obtained in a view level attribute
3) Now within your action handler method just use this reference to set the desired tab as selected

method WDDOMODIFYVIEW .
  check first_time = abap_true.
" Fetching the reference of the tabstrip. My tabstrip id is TABSTRIP
    wd_this->gv_tabstrip ?= view->get_element( id = 'TABSTRIP' ).
endmethod.
METHOD onactionset_focus_ontab1 .
" Use the earlier obtained reference to set the first tab as selected
" My first tab's id is TAB1
  wd_this->gv_tabstrip->set_selected_tab( value = 'TAB1' ).
ENDMETHOD.
