Nice :)
Don't want to be a pest (but maybe I'm helping out!)... It appears that AttachAnchorablesSource and DetachAnchorablesSource had each other's names mixed up...
I changed that but then my LayoutAnchorablePane isn't found here: (so I get no Anchorables in the Pane)
//look for an available pane
anchorablePane = layout.Descendents().OfType<LayoutAnchorablePane>().FirstOrDefault();
This is my XAML:
<adl:LayoutRoot> <adl:LayoutPanel Orientation="Horizontal"> <adl:LayoutAnchorablePane DockWidth="100" /> <adl:LayoutDocumentPaneGroup> <adl:LayoutDocumentPane /> </adl:LayoutDocumentPaneGroup> </adl:LayoutPanel> </adl:LayoutRoot>
