title: Exporting dataTable to dataGridView, not working
body: <p>I've been working on a project that takes two csv file as input, imported in dataTable.
  Now I wanted to join those two and finally show the joined one to a dataGridView.</p>
  
  <p>The program is working fine till the import part.</p>
  
  <p>The code that I've created so far does not show any error but it's not working, I mean, my destination Data Grid View remains blank.</p>
  
  <p>Please observe the following code and provide some solution that works.
  Best regards.</p>
  
  <p>P.S: I'm trying to do the Full Outer Join at here.</p>
  
  <pre><code>var tbl1 = tb1;
  var tbl2 = tb2;
  var res1 = from t2 in tbl2.AsEnumerable()
             join t1 in tbl1.AsEnumerable() on t2["BBL"] equals t1["BBL"] into g
             from t1 in g.DefaultIfEmpty()
             where t1 == null
             select t2;
  
  dataGridView3.DataSource = res1;
  </code></pre>
