title: Auto adding row to a DataGrid
body: <p>I'm programming in WPF(c#). I want a data grid that can automatically add new row to itself as you see in Sql-server :</p>
  
  <p><img src="https://i.stack.imgur.com/VttzI.png" alt="enter image description here"></p>
  
  <p>please look at the last row in the picture. In this control if you want to add new row you must fill three columns then a new row will be added automatically. How can I make some control like this with or without DataGrid? any idea?</p>
  
  <p>Thanks in advance</p>
