title: Get the value of hidden column in Gridview
body: <p>I am using a Gridview and wondering if there is way to hide a column from the Gridview but still be able to access the hidden column value.</p>
  
  <p>I set visible= false for the column that I want to hide but when I try to get the value of the column, the value in the column is empty.</p>
  
  <p>Thanks.</p>
