title: Dynamic Id on asp:Literal Cntrl
body: <p>I want to add Id's to some ctrls as below, depending on the id's I want to change the server-side values for these controls.
  But i am getting compile time error -not a valid identifier.
  I know that this can be done in code behind but just wanted to know if it is possible to do it on apsx page.</p>
  
  <p>Thanks for the concern   </p>
  
  <pre><code> &lt;asp:Literal ID="ltrlTotalAmount_&lt;%= trPlanYear.toString()%&gt;" runat="server"&gt;&lt;/asp:Literal&gt;
  </code></pre>
