Binding one DropDownList to another DropDownList
<p>I have two tables - <code>group</code> and <code>member</code>.</p>

<p>I have two DropDownList controls, one for <code>group_id</code> and the second for <code>member_id</code>.</p>

<p>If I select from the <code>group_id</code> DropDownList, I want only the members that are in that group to show in the second DropDownList. How do I bind the two DropDownList controls together?</p>
