Hello.

Here is code of my window:

<telerik:RadDocking x:Name="radDocking" PanesSource="{Binding Panes}">

<telerik:RadDocking.Resources>

<Style x:Key="RadPaneCustomStyle" TargetType="{x:Type telerik:RadPane}" BasedOn="{StaticResource RadPaneStyle}">

<Setter Property="Header" Value="{Binding Header}" />

<Setter Property="ToolTip" Value="{Binding ToolTip}" />

<Setter Property="IsHidden" Value="{Binding IsHidden, Mode=TwoWay}" />

<Setter Property="IsActive" Value="{Binding IsActive, Mode=TwoWay}" />

<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />

</Style>

<Style TargetType="{x:Type telerik:RadPane}" BasedOn="{StaticResource RadPaneCustomStyle}">

<Setter Property="CanDockInDocumentHost" Value="True" />

</Style>

<Style TargetType="{x:Type telerik:RadDocumentPane}" BasedOn="{StaticResource RadPaneCustomStyle}">

<Setter Property="CanDockInDocumentHost" Value="True" />

</Style>

</telerik:RadDocking.Resources>

<telerik:RadDocking.DockingPanesFactory>

<docking:CustomDockingPanesFactory />

</telerik:RadDocking.DockingPanesFactory>

<telerik:RadDocking.CurrentSaveLoadLayoutHelper>

<docking:CustomSaveLoadLayoutHelper />

</telerik:RadDocking.CurrentSaveLoadLayoutHelper>

<telerik:RadSplitContainer InitialPosition="DockedLeft">

<telerik:RadPaneGroup x:Name="leftGroup" telerik:RadDocking.SerializationTag="leftGroup" />

</telerik:RadSplitContainer>

<telerik:RadSplitContainer InitialPosition="DockedRight">

<telerik:RadPaneGroup x:Name="rightGroup" telerik:RadDocking.SerializationTag="rightGroup" />

</telerik:RadSplitContainer>

<telerik:RadSplitContainer InitialPosition="DockedBottom">

<telerik:RadPaneGroup x:Name="bottomGroup" telerik:RadDocking.SerializationTag="bottomGroup" />

</telerik:RadSplitContainer>

</telerik:RadDocking>

public void SaveLayout()

{

var docking = DockingManager as RadDocking;

using (var stream = File.Open(GetLayoutFilePath(State), FileMode.Create, FileAccess.Write, FileShare.ReadWrite))

{

docking.SaveLayout(stream);

}

public void LoadLayout(WorkspaceState state)

{

var docking = DockingManager as RadDocking;

using (var stream = File.Open(GetLayoutFilePath(State), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))

{

docking.LoadLayout(stream);

}

So, the problem is:
When i create some pads and save/load layout and dont hide or pin it it's ok. But when i pin it loose the style, so header become empty.
When i am hiding it and restoring, there is exseption:

System.InvalidOperationException was unhandled
