If you have a RadDock with child form in an MDI scenario, and you swtich between the tabs of the hosted forms, the Activated event of these forms will not be fired.

When RadDock.RightToLeft is Yes, the close buttons are correctly aligned to left (but not to right as it is by default). However, the text is not aligned to right, so the close button overlaps the text.

When you try to close a hidden ToolWindow in ActiveWindowChanged, you are prevented from docking ToolWindows which are in AutoHide mode.

If you try to close or set to autohide a ToolWindow in ActiveWindowChanged event and the ActiveWindowChanged is fired because you are trying to dock another ToolWindow (currently set to autohide), you may activate the wrong ToolWindow at the end.

When you set a ToolWindow in AutoHide DockState, hover the tab of the AutoHide window and set the focus to the window by a mouse click operation, you are not able to hide the window right after you click outside of the window.

Place a RadTextBox on a Form and sets its Anchor to Left, Top, Right. Let's say this form is a MDI child and RadDock hosts it. You will notice that the RadTextBox appears with a wrong size and a part of it is actually invisible.

If you hide a DocumentWindow and save the layout, the loaded layout shows the DocumentWindow, but it actually should keep it hidden.
Same behavior is valid for ToolWindow.

Steps to reproduce:
1) Create a parent MDI form - set isMdiContainer property to true
2) Create a child RadForm with some tool windows and document windows
3) Close the main MDI form without closing the child form Expected Result: close all forms Actual Result: Win32 Exception

If you set the CurrentCulture to tr-TR, you will notice that an unwanted black border appears in the FloatingWindow of RadDock. This scenario should be tested with the whole suite.

If you have several textboxes anchored to Left, Top, Right in a Form hosted in RadDock and you redock the window so that its width remains the same, the width of the textboxes will change.

Tooltip text inconsistency between the dock's buttons.After hovering contiguously two neighbour buttons, their tooltip text is swapped.

In case of two or more DocumentTabStrips in the DocumentContainer, the ZOrder of the DocumentWindows is not updated property.

1) Start with new Forms application.

2) Add RadDock set to Fill to the Form.

3) Open Designer.

4) Add ToolWindows docked Top and Right.  Add two ToolWindows docked fill.

5) Close Designer.

6) Open Designer.

7) Delete two docked ToolWindows.

8) Close Designer.

9) Deleted ToolWindows remain.  I also had them become tabbed with the 
ToolWindow docked to the Top in a previous test.

10) In the Designer, if I check the box, the two ToolWindows become docked
Left.  If I close the Designer and re-open it, I can then delete them.

11) I deleted all ToolWindows in the Designer and closed it.

12) The ToolWindows are removed.

13) Upon re-opening the Designer and adding windows, they do not appear
upon closing the Designer.

14) It appears that the documentContainer is missing from the DocumentOutline.
However, it is still present in the code because if I delete the RadDock, and
then re-add it, the name of the new documentContainer is numbered higher than
the first one.  If I try to rename it from 1 to 3, it tells me that 1 is still
in use.

15) Adding ToolWindows at this point works again.

If you dock several tool windows on the same position so that tabs show up and you double click the close button, all remaining docked windows will be made floating.

Put a RadTreeView in an AutoHide tool window and assign it with ContextMenuStrip with multiple levels of sub menu items. When you click a last-level menu item, the tool window will hide and the Click event of the item will not fire.

When reducing the size of a right-docked auto-hide tool window it goes out of the area of the RadDock

RadDock's layout does not handle correctly changed Windows DPI settings.

The order of tabs in not correct after RadDock save/load operation. The selected tab is always the last one.

RadDock's ToolWindow should not hide when a modal dialog is shown while working with the window.
Solution: Added AutoHideWindowHiding event to RadDock to allow cancelling of the auto-hide windows hiding.
