UI for WPF and UI for Silverlight

Still, its confusing for me. I am developing windows application using WPF, XAML and MVVM.

Now, I am using RadGridView and other telerik controls.

So, am I using Telerik UI for WPF or Telerik UI for Silverlight ?

 I am following these links

http://demos.telerik.com/silverlight/#Home

http://docs.telerik.com/devtools/silverlight/controls/radgridview/overview2

So, I am using UI for Silverlight but I am not deploying my applications on the web. How can we deploy WPF application on the web ?
