title: Magento 1.9 custom module csv delimiter
body: <p>I have made a custom module to export orders from magento with a custom SQL query. The whole module works great, however i want change the delimiter set on the csv export. After some searching i found out that setting a delimiter can be done in the Grid.php file in the construct. But this doesnt seem to work. This is how i have set it up.</p>
  
  <pre><code>public function __construct()
  {
      parent::__construct();
      $this-&gt;setId('exportorders_'.date('d_m_Y_h_i'));
      $this-&gt;setDelimiter('|');
      $this-&gt;setDefaultDir('DESC');
      $this-&gt;setSaveParametersInSession(true);
      $this-&gt;setUseAjax(true);
  }
  </code></pre>
  
  <p>Is there some alternative way of setting a delimiter for the csv export?
  I just want to set the delimiter for my custom module only.</p>
  
  <p>I appreciate any help or advice.</p>
