title: DataGridView.Rows.Count is 0
body: <p>I'm trying to read the content of an excel file (I must process the data not show it) but the number of rows is 0. I did show the data in the UI and the rows didn't have a number.</p>
  
  <pre><code>string src = "the path;";
  OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + src +
                                         "Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"");
  
  OleDbDataAdapter da = new OleDbDataAdapter("select * from [RENNES4_wk13$]", con);
  
  DataSet ds = new DataSet();
  da.Fill(ds);
  DataGridView dgv = new DataGridView();
  dgv.DataSource = ds.Tables[0];
  int rows = dgv.Rows.Count;
  int cells = dgv.Rows[0].Cells.Count;//ArgumentOutOfRange why?
  </code></pre>
  
  <p>How do I fix it?</p>
