title: c# Get DataTable from BindingSource and edit it
body: <p>I need to make some modifications to a <code>DataTable</code>that is connected to a <code>DataGridView</code> using a <code>BindingSource</code> without altering the grid.</p>
  
  <p>This is my code : </p>
  
  <pre><code>dtBallaFroc = new DataTable();
  //...Fill the datatable
  bindingSource.DataSource = dtBallaFroc;
  gridView.DataSource = bindingSource;
  </code></pre>
  
  <p>Later in the code I need to edit the datatable :</p>
  
  <pre><code> DataTable dataTable = (DataTable)bindingSource.DataSource;
  for (int i = 0; i &lt; dataTable.Rows.Count; i++)
  {
      dataTable.Rows[i][5] = 0;
  }
  </code></pre>
  
  <p>It works ok this way but it also edit my datagridview, how can I stop this ? </p>
