hi prodigy,
check this code using drop down list.
<b>layout for first page</b> 
<htmlb:dropdownListBox id                = "ddlist"
                              table             = "<%=t_mara%>"
                              nameOfKeyColumn   = "matnr"
                              nameOfValueColumn = "matnr"></htmlb:dropdownListBox>
<b>event Oninitialization event of first page</b>
SELECT MATNR UP TO 10 ROWS
  INTO TABLE T_MARA
  FROM MARA.
<b> event Oninputprocessing event</b>
**Load the manager class
CLASS CL_HTMLB_MANAGER DEFINITION LOAD.
DATA: V_EVENT TYPE REF TO CL_HTMLB_EVENT.
DATA: DATA TYPE REF TO OBJECT.
DATA: V_DATA TYPE REF TO CL_HTMLB_DROPDOWNLISTBOX.
CALL METHOD CL_HTMLB_MANAGER=>GET_EVENT
  EXPORTING
    REQUEST               = RUNTIME->SERVER->REQUEST
  RECEIVING
    EVENT                 = V_EVENT
IF V_EVENT->NAME = 'button' AND
   V_EVENT->EVENT_TYPE = 'click'.
DATA ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST =
                                      RUNTIME->SERVER->REQUEST
                                      NAME     = 'inputField'
                                      ID       = 'matnr'
    V_DATA ?= DATA.
IF V_DATA IS NOT INITIAL.
     V_MATNR = V_DATA->SELECTION.
ENDIF.
NAVIGATION->SET_PARAMETER( NAME = 'v_matnr' VALUE = V_MATNR ).
NAVIGATION->GOTO_PAGE( 'detail.htm' ).
