title: asp.net selectedvalue bind conditionally
body: <p>I like to do a conditional bind. For example if the SelectedValue is null,
  I like to bind it to "Pacific Time".
  Below does not work but will give you an idea of what I am trying to do</p>
  
  <pre><code>    SelectedValue='&lt;%# Bind("Zone") ?? "Pacific Time" %&gt;'
  </code></pre>
