title: Change header text of columns in a GridView
body: <p>I have a GridView which i programmatically bind using c# code.
  The problem is, the columns get their header texts directly from Database, which can look odd when presented on websites. So basically, i would like to modify the column header text, but programmatically.
  i have already tried the following, </p>
  
  <pre><code>testGV.Columns[0].HeaderText = "Date";
  </code></pre>
  
  <p>and</p>
  
  <pre><code>this.testGV.Columns[0].HeaderText = "Date";
  </code></pre>
  
  <p>does not seem to give me correct result.</p>
