Hi,
When you want to navigate to create view?. when click on Ok button or when selecting radio button..?
If you want to navigate to create view when click on ok button you need to write in OnActionOk. else for radio button also you will have one event called onSelect. You can create an action for that and write your code.
In onActionOk or onActionCreate,
Read the attribute using wizard to which you bind your radio button texts.
Let say you created a node called NODEA with cardinality 0..n and you created attribute TEXT under NODEA and you binded your radiobutton texts to TEXT attribute under node.
Now Read the attribute TEXT under NODEA using wizard.
now it will automatically generate code.
Now lv_text contains the selected radio button text.
if lv_text is create,
Navigate to create view using fire outbound plug.
check this code below,
DATA lo_nd_rdb TYPE REF TO if_wd_context_node.   " here rdb is your node name.
    DATA lo_el_rdb TYPE REF TO if_wd_context_element.
    DATA ls_rdb TYPE wd_this->Element_rdb.
    DATA lv_text TYPE wd_this->Element_rdb-text.
*   navigate from <CONTEXT> to <RDB> via lead selection
    lo_nd_rdb = wd_context->get_child_node( name = wd_this->wdctx_rdb ).
*   @TODO handle non existant child
*   IF lo_nd_rdb IS INITIAL.
*   ENDIF.
*   get element via lead selection
    lo_el_rdb = lo_nd_rdb->get_element( ).
*   alternative access  via index
*   lo_el_rdb = lo_nd_rdb->get_element( index = 1 ).
*   @TODO handle not set lead selection
    IF lo_el_rdb IS INITIAL.
    ENDIF.
*   get single attribute
    lo_el_rdb->get_attribute(
      EXPORTING
        name =  `TEXT`
      IMPORTING
        value = lv_text ).   " this lv_text contains your selected radio button value
if lv_text = 'Create'.
wd_this->fire_to_create_plg(       " here to_create is the outbound plug name.
elseif ....
endif.
