"Disable Resizing of the Panes
In order to disable the pane resizing, you need to use the MinWidth, MinHeight, MaxWidth and MaxHeight properties of the RadSplitContainer."
How is this achieved? The ActualWidth/ActualHeight, DesiredSize and RenderSize properties are either zero or the incorrect sizes. I cannot find any suitable properties I can use and also I do not understand why this would freeze the sizes of the panes that are contained in the RadSplitContainer
Thanks
