title: Dynamic IDs on asp:TextBox?
body: <p>This is my code, on a <code>.ascx</code> page :</p>
  
  <pre><code>&lt;% for (int i = 1; i &lt;= 10; i++) 
     { %&gt;
      &lt;asp:TextBox ID="myTextBox_&lt;%=i %&gt;" runat="server" Width="100%" CssClass="focus_out reset_content"&gt;&lt;/asp:TextBox&gt;
  &lt;% } %&gt;
  </code></pre>
  
  <p>but I get <code>myTextBox_&lt;%=i %&gt;</code> is not a valid identificator. So, how can I put "Dynamic IDs"?</p>
