title: SqlDataSource onSelected event not firing
body: <p>I have an SqlDataSource control with a selectcommand that doesn't fire onselected event (while another one, very similar, fires it).
  The one that doesn't fire:</p>
  
  <pre><code>&lt;asp:SqlDataSource ID="CommunicationSQLDataSource" runat="server" ConnectionString="&lt;%$ ConnectionStrings:aspnet-WebApplication6-20131007103938ConnectionString1 %&gt;" 
      SelectCommand="SELECT * FROM tCommunication" OnSelected="CommunicationSQLDataSource_Selected"&gt;
       &lt;SelectParameters&gt;
          &lt;asp:Parameter Type="String" Name="ProjectID"&gt;&lt;/asp:Parameter&gt;
      &lt;/SelectParameters&gt;
  &lt;/asp:SqlDataSource&gt;
  </code></pre>
  
  <p>(The one that fires, just for reference)</p>
  
  <pre><code>&lt;asp:SqlDataSource ID="DetailsSQLDataSource" runat="server" ConnectionString="&lt;%$ ConnectionStrings:aspnet-WebApplication6-20131007103938ConnectionString1 %&gt;"
      SelectCommand="SELECT [ProjectID], ..." OnSelected="DetailsSQLDataSource_Selected"&gt;
      &lt;SelectParameters&gt;
          &lt;asp:Parameter Name="ProjectID" Type="Object" /&gt;
      &lt;/SelectParameters&gt;
  &lt;/asp:SqlDataSource&gt;
  </code></pre>
  
  <p>What I see is that the debugger doesn't reach the block of CommunicationSQLDataSource_Selected even though it is referenced in the control.</p>
