body: <p>How to find all the expanded or collapsed rows in Kendo UI grid hierarchy?
  I can find the count of all the masterrow using below code but I want to interate through each and check which all are expanded.</p>
  
  <pre><code>var grid = $("#gridList").data("kendoGrid");
  var allMasterRows = grid.tbody.find('&gt;tr.k-master-row') 
  </code></pre>
  
  <p>I have tried below code but it does not work</p>
  
  <pre><code>var strPlus = (grid.tbody.find("k-icon k-plus"));
  </code></pre>
  
  <p>Please suggest.    </p>
