When dragging item from the RadListBox the drag visual of the dragged item should be visible. The example should show an approach similar to the approach found here (http://www.telerik.com/community/code-library/wpf/docking/how-to-enable-drag-and-drop-from-radlistbox-to-raddocking-controls.aspx) but without the mentioned limitations.

The fix will be available in the R1 2018 SP2 Release.

It happens when the Pane is dragged and dropped not on the Compass several times, quickly.

Available in LIB version 2017.3.1225, it will be also available in the R1 2018 Release.

The compasses of the other ToolWindow appear.

workaround:
add the following visual state to the DocumentHostTemplate of the RadPaneGroup:

<VisualStateManager.VisualStateGroups>
    <VisualStateGroup x:Name="DropDownDisplayStates">
        <VisualState x:Name="DropDownButtonCollapsed" />
        <VisualState x:Name="DropDownButtonVisible">
            <Storyboard>
                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="DropDownButtonElement" Storyboard.TargetProperty="Visibility">
                    <DiscreteObjectKeyFrame KeyTime="0">
                        <DiscreteObjectKeyFrame.Value>
                            <Visibility>Visible</Visibility>
                        </DiscreteObjectKeyFrame.Value>
                    </DiscreteObjectKeyFrame>
                </ObjectAnimationUsingKeyFrames>
            </Storyboard>
        </VisualState>
    </VisualStateGroup>
</VisualStateManager.VisualStateGroups>

and remove the trigger targeting the drop down button.

Make it possible to set fixed WIdth/Height sizes to the PaneGroups. In the current version setting the Width/Height properties of the PaneGroup leads to incorrect placement of the groups while docked in the control.

Available in the 2017 R2 Release.
