Currently, unpinned panes need to first be pinned in order to be floated. Floating of unpinned panes should be made possible.

When you create a custom PaneGroup by adding a class that inherits RadPaneGroup make it possible that the built-in Save/Load layout functionality loads those PaneGroups.

Available in the 2016 R2 release.

The compass is out of place when specific height is set to the dock and the window is made smaller than the docking height

In WPF when show the unpined pane by hovering, when right click to show the contextmenu the pane collapses.

Steps to reproduce:
1. Start the WPF Controls Example application on a terminal server
2. Select Docking example
3. Try to move a floating windows by dragging it with the mouse
4. The window will move for a split second, but stop moving after that. (It behaves as if the mouse button was released after the initial move)

When all of the RadDocument panes in the DocumentHost are closed the last one stays alive in .Net Framework 4.0. The issues can't be reproduced on machines with .Net Framework 4.5 installed

In some scenarios the SplitterChange is not rounded number and this cause invalid layout load. 

Workaround: Edit the saved xml and round the value.

When the DragDropMode property is set to Deferred in partial trusted applications a security excpetion is being thrown.

1. Create an app using RadDocking. The 'First Look' demo of RadDock can be modified to reproduce the problem.
2. Modify one of the panes, replace the TextBlock control with a TextBox control. Bind the text of the TextBox control to a string property.
3. Add the string property to the .cs file and in the setter, Show a MessageBox.
4. Run app. Select tab with Textbox control and modify the value.
5. Now select the other tab. the messagebox will be displayed. Notice it can be dismissed via keyboard but not via mouse click. It cannot be moved via mouse either.
6. Select a window outside of the application and not select the message box. Notice Mouse input now works. MessageBox can be moved and dismissed via mouse.

If DragDropMode is set to Deferred when trying to dock a Pane inside a compass that is over the dragged Pane, the dock operation is not completed correctly.

Available in LIB version 2016.2.516, it will be also available in the R2 2016 SP1 Release.

If the IsContentPreserved of a PaneGroup is SET to true and a RadTabControl is placed inside a Pane the focus is moved through its content.

If a SplitContainer's InitialPosition is set to FloatingDockable and the the layout is saved in the Unloaded event of the control, that SplitContainer is not shown after layout load.

The same could be observed if you float a Pane by dragging it out of its docked state.

Make it possible to be able to set separate header and content ToolTip of a RadPane

Dragging objects from outside control shouldn't be allowed in specific cases. In cases where the RadDocking control cannot use the dragged data, the drop operation shouldn't be allowed.

If you have RadPane inside DocumentHost and you try to set IsHidden=true after InitializeComponent, it will not be applied and the pane will remain visible.

With code below the radPane will remain hidden (radPane is floating pane):radPane.IsHidden = true;

radPane.IsHidden = false;

Available in LIB version 2016.2.530, it will be also available in the 2016 R2 SP1.

When RadGridView/DataGrid is placed inside a floating Pane and the Docking parent is resized, hovering over the compasses cases a highlight in the GridView/DataGrid
