title: where is the other partial class definition of my default.aspx.cs?
body: <p>I built an empty website on VS 2010.
  Using the toolbox I put a DataGridView on my default.aspx.
  Then I configured the sql query that fills it from the DataSource.
  I wanted to see the ADO code that is done under the covers. 
  But all there is the default.aspx file, and the default.aspx.cs:</p>
  
  <pre><code>public partial class _Default : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e) {}    
  }
  </code></pre>
  
  <p>this is the aspx:</p>
  
  <pre><code>&lt;asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
          CellPadding="4" DataSourceID="SqlDataSource2" ForeColor="#333333" 
          GridLines="None" ondatabound="GridView1_DataBound"&gt;
          &lt;AlternatingRowStyle BackColor="White" ForeColor="#284775" /&gt;
          &lt;Columns&gt;
              &lt;asp:BoundField DataField="Title" ...
  </code></pre>
  
  <p>the web.config:</p>
  
  <pre><code>&lt;configuration&gt;
   &lt;connectionStrings... 
   &lt;system.web&gt;
    &lt;compilation debug="true" targetFramework="4.0"/&gt;
   &lt;/system.web&gt;
   &lt;system.webServer&gt;
    &lt;modules runAllManagedModulesForAllRequests="true"/&gt;
   &lt;/system.webServer&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Where did the .designer.cs file gone?
  Or maybe the aspx markup is all there is?
  And if so how?
  And where is the other partial class definition (if I delete the word 'partial' VS won't compile and says that there is another partial class definition) ?</p>
