Release LIB 2019.3.1007
The CustomElementLoading event can't be canceled without creating a new instance of the custom element.

As a workaround in the CustomElementLoading event handler you can call the SetAffectedElement() with creating DependencyObject and then Cancel the event by setting the Cancel property.
private void RadDockingOnCustomElementLoading(object sender, LayoutSerializationCustomLoadingEventArgs e)
{
    if (e.CustomElementTypeName == "MyRadPane")
    {
        e.SetAffectedElement(new DependencyObject());
        e.Cancel = true;              
    }
}

Release LIB 2019.2.603 (06/03/2019)
When the IsHidden property of a RadPane within a ToolWindow is set to True and then to false in quick succession, the ToolWindow is not shown. 

As a workaround, you can disable the animation of the ToolWindow:
<Style TargetType="telerik:ToolWindow">
<Setter Property="telerik:AnimationManager.IsAnimationEnabled" Value="False" />
</Style>

The above style need to be placed in the resources of the App.xaml in order to take effect on the ToolWindows, since they are displayed in a separated visual tree.

Release R3 2019 SP1

Hello Support,

we are using the RadDocking.LayoutChangeEnded event to store the docking layout (via RadDocking.SaveLayout) after the user has changed it.

When animations are enabled (default) everything works as expected and all groups, split containers, and panes are included when in the XML written by RadDocking.SaveLayout.

However, when disabling animations (either using AnimationManager.IsGlobalAnimationEnabled or custom styles for RadWindow and/or ToolWindow setting AnimationManager.IsAnimationEnabled to false) the RadDocking.LayoutChangeEnded event is raised too early.

The faulty behavior can be reproduced with the attached demo application as follows:

1. start the application (App.xaml includes a style for ToolWindow with animations disabled)

2. drag the pane "Solution Explorer" out of the application to create a new tool window

3. drag the "Solution Explorer" tool window onto the "Properties" pane's compass and drop it below "Properties", so that "Properties" and "Solution Explorer" are both pinned right in the application above each other

4. when inspecting the layout written to the "Output" pane you will find that the entry for the RadPane "Solution Explorer" is missing

Any additional change to the docking layout (like resizing a pane) will update the layout and show all panes again.

When enabling animations in the ToolWindow style the above steps will result in the complete layout being written to the "Output" pane.

Please let me know should you require further information for reproduction of this bug.

Best regards,

Oliver

When the RadDocking Items are reordered during runtime and new RadSplitContainers/RadPaneGroups are generated, the save/load behavior is sometimes incorrect.

Release LIB 2019.1.422 (04/22/2019)

Dynamically adding RadPane to PaneGroup, the header of the pane does not appear on the second added pane.

To workaround this the OnApplyTemplate() method can be called after the RadPane is added to the RadPaneGroup.

The close button in the document host is not higlighted (hovered-button-state-doc-host.png) as opposed to panes outside the DocumentHost area (hovered-button-state.png).

The workaround is to update the MouseOver visual state of the RadButtonDocumentCloseControlTemplate:

             <ControlTemplate x:Key="RadButtonDocumentCloseControlTemplate" TargetType="telerik:RadButton">
                <Grid x:Name="LayoutRoot" Background="Transparent" Width="18" Height="18">

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.
