'Not selected' property value on drop down box selected value
<p>I have an ASP.NET site (either .NET 2.0 or 3.5), and I want to get the selected item of two drop down boxes (call them a and b). B is updated with appropriate values depending on what is selected for A.</p>

<p>However, the following code:</p>

<pre><code>string val = dd1.SelectedItem.Text;
</code></pre>

<p>Returns a value of "not selected". Why is this?</p>

<p>Thanks</p>
