title: Process after grid was loaded completely using ExtJS
body: <p>I am using ExtJS to load data to a grid, and I want to add some additional processes after data was put on grid completely.</p>
  
  <p>My context is, after data was put on grid, I will check all rows, and mark some of them as disabled based on a specified condition and put tooltip to row (explain why it is disabled). I tried to use 2 events: 'afterrender' of Grid, and 'load' of grid's store, but they did not work.</p>
  
  <p>Because <code>grid's 'afterrender'</code> was fired when first grid initialization, not concern to data load. <code>store's 'load'</code> was fired when data was prefetch to store (not render on screen), so I cannot get the row <code>&lt;div&gt;</code> to style it as disabled.  </p>
  
  <p>So, what is the event to detect when data was loaded and rendered completely on grid? And how can I implement this requirement?</p>
