How to display data in tableview based on a dropdown filter selection

Question

Hi All,
I have implemented a flow logic based BSP page to display the SFLIGHTS table when I open this page it displays all records in the table SFLIGHTS. I would like the set a drop down box filter on CARRID and CONNIND. Only once the user selects the CARRID and CONNID and presses on display buttont the data for that selection in the drop down box should be displayed.
Can you kindly share the code how I can put 2 drop down boxes and make the data retrieval on the page occur based on the dropdown box selection. The layout page is  as below. Appreciate if you could kindly share the code to implement this.
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design="design2003" >
  <htmlb:page>
    <htmlb:form>
      <htmlb:tableView id              = "tv1"
                       visibleRowCount = "10"
                       selectionMode   = "lineEdit"
                       table           = "<%= flights %>"
                       filter = "SERVER"
                       sort = "server"
                       iterator        = "<%= iterator %>" />
    </htmlb:form>
  </htmlb:page>
</htmlb:content>
Thanks

Yeh Karen,
What  i have written is that only.. ok fine i will tell you in detail ok...
first what you do is if ur wrking with MVC concept in *do request * add the code for the dropdown as
select single connid from sflights into wa_sflights.
this code will give you the coniid  in the dropdown ok
if you not wrking with MVC ,if its just a Flow with page login then write the same code in Oninitialization
now if you select the connid from the dropdown and you want to display the details of the that connid in the tableview .. rite?
then in do handle event write the code when i have written before  if itsnot MVC add in oninputProcessing
DATA: HTMLB_EVENT TYPE REF TO CL_HTMLB_EVENT,
W_ID TYPE STRING,
W_VARIABLE TYPE STRING,
tvdata TYPE REF TO CL_HTMLB_TABLEVIEW.
IF HTMLB_EVENT IS NOT INITIAL.
W_ID = HTMLB_EVENT->ID.
IF W_ID EQ 'dd_project_name' . ------>this is the name of the dropdown
    DATA ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = RUNTIME->SERVER->REQUEST
                         NAME = 'dropdownListBox'
                         ID = 'dd_project_name' ).
    IF DATA IS NOT INITIAL.
      W_variable = DATA->SELECTION.
    ENDIF.
if w_variable is not initial.
select * from sflights into table lt_flights where connid eq w_variable.
endif.
now in the view you should
<htmlb:tableView id = "tv1"
visibleRowCount = "10"
selectionMode = "lineEdit"
table = "<%= lt_flights %>"
filter = "SERVER"
sort = "server" />
Hope it works fine
