title: Check if String / Record exists in DataTable
body: <p>I have a String and I need to check if any column "item_manuf_id" in DataTable dtPs.Rows equals to certain value</p>
  
  <p>I can loop over all Rows and compare</p>
  
  <pre><code>String id = dtPs.Rows[number]["item_manuf_id"].ToString()
  if ("some value".equals(id)) etc.
  </code></pre>
  
  <p>but I am wondering if there is any way to check if <code>DataTable</code> contains the record</p>
