Dependent Drop Downs in ASP.NET
<p>I must be having brainfade but I can't get two dependent drop-downs to work.</p>

<p>In the Page load event I am setting the values in my first dropdown if this is not a postback. In the selectedindexchanged event of this drop down I am clearing a second drop-down and adding items based upon the value in the first drop-down. The items are added manually with no use of data-binding.</p>

<p>If I step through the code I can see that the second drop-down is cleared and items are added to it correclty. However, they don't appear in the web page - the second drop-down remains empty.</p>

<p>Help</p>

<h2>UPDATE</h2>

<p>Thanks for all the suggestions. I found the problem. The page used an Infragistics asynch panel for ajax postbacks. This was causing the issue.</p>
