title: I want to have a validation on my Custom Screen Setup
body: <p>I want to implement on and off switch feature on my acumatica custom setup screen.</p>
  
  <p>Let's say I want to implement:</p>
  
  <p><code>feature1</code></p>
  
  <p><code>feature2</code></p>
  
  <p><code>feature3</code></p>
  
  <p>When I tick feature1, the corresponding screens with that Feature, its okay to me if it is still visible on the sitemap, or when a user enter to that screen it will prompt the user that the module is not available or not setup for the instance.</p>
  
  <p>I'm using the constructor with the same ClassName as the GraphName like</p>
  
  <pre class="lang-cs prettyprint-override"><code>public MyGraphClassName()
  {
      throw new PXException("Error goes here for the Initialization method");
  }
  </code></pre>
  
  <p>But when I do this, the screen where the DAC was applied is also giving an error, whereas it must still continue because it is only a partial of that screen. How will I do it?, I've also done using _RowSelected() event, it seems not working. I'm lost.</p>
