working with dropdownlist in asp.net c#
<p>i have 2 dropdownlist in asp.net c#, one has only two items in it('OK' 'PK') and the other one is bound to a database field and it has 158 items in it.</p>

<p>I want remove two Items from the second list when the user selects 'OK' and keep original list when user selects 'PK'.</p>

<p>How can i do it?? As i have bound the second list to a database is there any property which can hide some values in the list??</p>
