title: Why isn't selectedindexchanged firing?
body: <p>I have the following DropDownList defined:</p>
  
  <pre><code>&lt;asp:DropDownList ID="ddlStuff" CssClass="myCssClass" OnSelectedIndexChanged="PopulateAnotherDropdown" runat="server"&gt;&lt;/asp:DropDownList&gt;
  </code></pre>
  
  <p>However, my PopulateAnotherDropdown method isn't firing.  I have a breakpoint set on the method, and it's not being hit.</p>
  
  <p>Here is my method write-up in code-behind:</p>
  
  <pre><code>public void PopulateAnotherDropdown(object sender, EventArgs e)
  {
      ...
  }
  </code></pre>
  
  <p>For what it's worth, the page is rendering as follows:</p>
  
  <pre><code>&lt;select name="ctl00$MainContent$ddlStuff" id="MainContent_ddlStuff" class="myCssClass"&gt;
  </code></pre>
  
  <p>Any ideas?</p>
