title: This Row already belongs to another table error when trying to add rows?
body: <p>I have a DataTable which has some rows and I am using the select to filter the rows to get a collection of DataRows which I then loop through using foreach and add it to another DataTable, but it is giving me the error "This Row already belongs to another table".  Here is the code:</p>
  
  <pre><code>DataTable dt = (DataTable)Session["dtAllOrders"];
  DataTable dtSpecificOrders = new DataTable();
  
  DataRow[] orderRows = dt.Select("CustomerID = 2");
  
  foreach (DataRow dr in orderRows)
  {
      dtSpecificOrders.Rows.Add(dr); //Error thrown here.
  }
  </code></pre>
