title: Asp.Net, DropDownList, AutoPostBack and Google Chrome
body: <p>I've a simple asp.net page (framework 3.5) and an UpdatePanel with a series of dropdownlist I want to populate asyncronously. All works fine in all major browsers (Opera, Safari, IE6, IE7, FF3), but not in Chrome.</p>
  
  <p>Chrome seems to ignore the SelectedIndexChanged event who had to make the asynch request.</p>
  
  <p>Anyone knows a simple workaround to this?
  Thanks!</p>
  
  <p>EDIT: More Informations</p>
  
  <p>As I say to Adam Lassek, the updatepanel refresh after the click to an asp:Button inside of it, but it doesn't work with the dropdown's <code>SelectedIndexChanged</code> event.</p>
  
  <p>The updatepanel is set like:</p>
  
  <pre><code>&lt;asp:UpdatePanel ID="updPanel" runat="server" UpdateMode="Always" ChildrenAsTriggers="true"&gt;
  </code></pre>
  
  <p>without Triggers specified, and the dropdows have sets <code>AutoPostBack="true"</code></p>
  
  <p><strong>UPDATE:</strong> (and retagging)</p>
  
  <p>After a few attempts I discover that it isn't a problem of the UpdatePanel, but it seems that the AutoPostback of dropdowns doesn't work properly, even in pages without ScriptManager and UpdatePanel...
  I'm sure that it is a problem concerning only this project, because if I start a new WebSite from scratch and replicate the structure of this, works fine in Chrome...
  I'm trying to remove step by step all the other things in the original project to find exactly what's the problem.</p>
  
  <p>If anyone has some ideas in meantime....</p>
