title: C# Winform DataGridView inline add New row
body: <p>I want to add a new item into my datagridview. I know can achieve this using several TextBoxes and a Button. When the user clicks this button, it will add a new item into database and refresh my datagridview.</p>
  
  <p>I wonder if I can use the last row of my datagridview to add a new item. How can I do that?</p>
