how to pass parameter in ado.net source

Hi,

i am using ado.net source in ssis to get data from cache database. I have defined two variables startdate and enddate and want to pass it using parameter into the sql query. But in ado.net source there is no parameter mapping tab. I need help to do it.

Below is my get part code.

select  distinct
convert(int,0)  as CalendarID,
d.ItemNumber                        as ProductCode,
