Normal UpdatePanel behaviour? ASP.NET
<p>Am I doing this correctly?</p>

<p>I have two dropdowns. The first is populated on form load, and it is a trigger for an updatepanel that contains the 2nd dropdown.</p>

<p>When I change the value in the first dropdown box, it triggers the 2nd one's updatepanel, which populates it.</p>

<p>However, when I select a value in the 2nd dropdownbox, it triggers itself and repopulates... so if I select the 2nd or 3rd item in the dropdown, it repopulates and selects the first item again.</p>

<p>Am I doing something wrong, or is this normal?  Should I put the first dropdown into an updatepanel instead and have it trigger itself, and in its own trigger, populate the 2nd listbox?</p>
