Most of the controls you use have their equivalents in the Silverlight suite. The Splitter
control can be replaced with Grid
panel with GridResizer
control for the simple scenarios (only resizing) or with Docking
control for the more complex scenarios. You can see the demos for the Docking control for Silverlight here: http://demos.telerik.com/silverlight/#Docking/FirstLook
The timeline view of the Scheduler
control is under development at this time. It will be included in the beta version that should be ready for the next week.
