Hello,
The problem occurs when you have a floating panel
I modified your sample to reproduce the issue
Take a look on :
<UserControl x:Class="Docking_TEST_SL.MainPage"
mc:Ignorable="d"
xmlns:alf="clr-namespace:Core.Converters"
xmlns:local="clr-namespace:Docking_TEST_SL"
d:DesignHeight="300" d:DesignWidth="400"
<UserControl.Resources>
<local:ViewModel x:Key="MyViewModel"/>
<alf:BooleanToVisibilityConverter x:Name="btoV"/>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White" >
<Grid.Resources>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel>
<telerik:RadRadioButton x:Name="_btnAdmin" Content="click to change" IsChecked="False" GroupName="grp" />
<telerik:RadRadioButton Content="click to change" GroupName="grp" />
</StackPanel>
<telerik:RadDocking VerticalAlignment="Stretch" x:Name="Docking" Background="{x:Null}" Grid.Row="1"
BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="0,0,0,0" HasDocumentHost="False" >
<telerik:RadSplitContainer InitialPosition="DockedRight">
<telerik:RadPaneGroup>
<telerik:RadPane Header="Pane 1"
CanUserClose="False" CanFloat="False" CanUserPin="False" CanDockInDocumentHost="False">
<Button x:Name="button" Visibility="{Binding IsChecked}"/>
</telerik:RadPane>
</telerik:RadPaneGroup>
</telerik:RadSplitContainer>
<!--HERE if you change on "DockedRight" it works !-->
<telerik:RadSplitContainer InitialPosition="FloatingDockable"

</telerik:RadPane>
</telerik:RadPaneGroup>
</telerik:RadSplitContainer>
</telerik:RadDocking>
