title: How to Update DataTable
body: <p>I have a main <code>DataSet</code> which contains several <code>DataTables</code>. These different DataTables are bound to their DataGridView's DataSource respectively. </p>
  
  <p>My problem is whenever I modify something in the display area such as the description textbox below and then click on save....</p>

  <p>The DataGridView doesn't have the replicated changes, as seen here:

  <p>I need a way to update the DataTable ... My save button successfully saves the information. I am quite new to DataSets and DataTables so this is my first time trying to update a DataTable. I doubt I need to reload the information in the DataTable, there must be something more efficient? </p>
