title: How to Get row by key value or visible index in ASPxGridView then change column value?
body: <p>Hi<br>
  In ASPxGridView, is there a way to get a row by its VisibleIndex or KeyValue so that I can change any column value in it?, I mean something like this:  </p>
  
  <pre><code>var row = myGrid.SelectRowByKeyValue(myKeyValue);
  OR:
  var row = myGrid.SelectRowByVisibleIndex(myKeyValue);  
  
  row["Column1"] = true; 
  </code></pre>
  
  <p><strong>Edit:</strong><br>
  What I'm tring to do is that every time I hit the button I want to check one specific row (I'm using ajax to not reload all the page);</p>
  
  <p>Thanks</p>
