title: Differences between .NET 4 WPF Datagrid and WPF Toolkit Datagrid
body: <p>Can anyone tell me what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit?  I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.  </p>
  
  <p>I needed a WPF datagrid quick and have utilized the toolkit version in my applications.  I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.  </p>
