Hello,

I was able to reproduce this behavior and also found out what is the reason behind it. When template is extracted it seems that some properties are missing. Such properties are those having RelativeSource binding. Simply change your control template's part for <telerik:RadSplitButton.DropDownContent> as shown below:

<ListBox x:Name="HistoryListBox" BorderThickness="0"

Background="White" ItemsSource="{TemplateBinding HistoryItems}"

SelectedItem="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=SelectedHistoryItem, Mode=TwoWay}"

Foreground="{TemplateBinding Foreground}"

FontSize="{TemplateBinding FontSize}"

HorizontalContentAlignment="Stretch"

MinHeight="28"

Padding="3"

VerticalContentAlignment="Stretch">

<ListBox.ItemContainerStyle>

<Style TargetType="{x:Type ListBoxItem}">

<Setter Property="BorderThickness" Value="0"/>

<Setter Property="Padding" Value="0"/>

<Setter Property="HorizontalContentAlignment" Value="Stretch"/>

<Setter Property="VerticalContentAlignment" Value="Top"/>

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type ListBoxItem}">

<Grid x:Name="root">

<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</ListBox.ItemContainerStyle>

</ListBox>

In case you need to use some specific theme's style you can see the control template for it by navigating to the desired theme folder (<your_installation_folder>\UI for WPF Q2 2015\Themes.Implicit\WPF40\OfficeBlack\Themes) and explore the appropriate xaml file. In this case that would be Telerik.Windows.Controls.Navigation.xaml.

Hope this helps.
