HI Hema,
What i understood from u r query is u want 2 refrsh all ui elements data.
u can read data from the respective nodes and clear those data.
Example: I want to delete contents of an ui element on the screen( FULL_NAME ).
create a buuton REFRESH  on the screen and assicn a action to that button.u wil get a method with that action.write this follwing code in tat method.
method ONACTIONREFRESH_UI .
    DATA lo_nd_processedby TYPE REF TO if_wd_context_node.
    DATA lo_el_processedby TYPE REF TO if_wd_context_element.
    DATA ls_processedby TYPE wd_this->element_processedby.
    DATA lv_full_name LIKE ls_processedby-full_name.
  navigate from <CONTEXT> to <PROCESSEDBY> via lead selection
    lo_nd_processedby = wd_context->get_child_node( name = wd_this->wdctx_processedby ).
  get element via lead selection
    lo_el_processedby = lo_nd_processedby->get_element(  ).
  get single attribute
    lo_el_processedby->get_attribute(
      EXPORTING
        name =  `FULL_NAME`
      IMPORTING
        value = lv_full_name ).
clear lv_full_name.
CALL METHOD lo_el_processedby->set_attribute
  EXPORTING
    value  = lv_full_name
    name   = `FULL_NAME`
endmethod.
