title: WPF DataGrid not appear in Toolbox?
body: <p>I am working with Visual studio 2008. I want to work on WPF DataGrid control.</p>
  
  <p>I downloaded <a href="http://wpf.codeplex.com/releases/view/40535" rel="nofollow noreferrer">WPF toolkit</a> and install it, and then added toolkit reference in my project, but it does not recognize Datagrid control, and does not show it in Toolbox, I even try to add it in toolbox through <strong>choose Item..</strong>  but when I click WPFToolkit.dll, it gives the error. And even if I write code in XAML it does not recognize dataGrid.</p>
