title: How to implement DataTable property with INotifyPropertyChanged
body: <p>I have created WPF MVVM application, and set WPFToolkit DataGrid binding to DataTable so I want to know how to implement DataTable property to notify changed. Currently my code is like below.</p>
  
  <pre><code>public DataTable Test
  {
      get { return this.testTable; }
      set 
      { 
          ...
          ...
          base.OnPropertyChanged("Test");
      }
  }
  
  public void X()
  {
      this.Test.Add(...); // I suppose this line will call to getter first (this.Test = get Test) and then it will call add letter, this mean that setter scope will never fire.
      base.OnPropertyChanged("Test"); // my solution is here :) but I hope it has better ways.
  }
  </code></pre>
  
  <p>Is it has another solution for this problem?</p>
