title: CRM 2011 subgrid - custom form
body: <p>Could you please help me with my issue.</p>
  
  <p>I have custom entity (for example <strong>custom_X</strong>).
  In Invoice(CRM) I created subgrid - this is view for <strong>custom_X</strong>.</p>
  
  <p>In <strong>custom_X</strong> I have field <em>type</em>. </p>
  
  <p>So my question: 
  How can I open default form for <strong>type 1</strong> and custom form for <strong>type 2</strong>? 
  (This is one entity. So it is posssible?)</p>
