I created a new WPF application using the SyncFusion wizard. I chose the Visual Studio option to try out the docking manager.
I collapsed the panel containing the solution explorer (and others) so that it appears as buttons.
I mouse over the properties panel, grab its header, and try drag and snap it to the right of the children.
'The visual tree has been changed during a 'VisualTreeChanged' event.'
I run the program again:
I turned off the option for IsAnimationEnabledOnMouseOver using the menu.
I collapsed the panel containing the solution explorer (and others) so that it appears as buttons.
I dragged the properties window and snapped it to the right of the child windows. The solution explorer window is auto collapsed.
I clicked its button so it appears, then dragged it, to drop it into the top part of the properties panel.
'The visual tree has been changed during a 'VisualTreeChanged' event.'
Conclusion: cute but unstable
