title: How to sort gridview to show by specific column the row
body: <p>I've tried for so many times to find a way to sort my gridview but I couldn't find a way to do it.</p>
  
  <p>Table Columns: </p>
  
  <pre><code>Name | Age | Old device name
  ============================
  John | 22  | KRT 20
  Jon  | 21  | KSR 12
  Jco  | 22  |
  </code></pre>
  
  <p>I would like to know how can I make a drop list , to choose in the gridview to sort all the rows by Old device name , so I should see in the gridview only the rows that contains the old device name.</p>
  
  <p>I'm using a SqlDataSource and GridView in ASP.NET.</p>
