Just try it, it throws a nullreference on "base.ApplyTemplate()".

Here is my control template:

<Style TargetType="local:CustomFrame">

<Setter Property="IsTabStop" Value="False"/>

<Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>

<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeNormal}"/>

<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>

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

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

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

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

<Setter Property="Background" Value="{x:Null}"/>

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

<Setter Property="BorderBrush" Value="{x:Null}"/>

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

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="local:CustomFrame">

<Border x:Name="ClientArea" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}" d:DesignHeight="800" d:DesignWidth="480" >

<Border.Resources>

<Storyboard x:Name="ShowLoadingSB">

<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="LoadingOverlay"/>

<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="LoadingOverlay">

<DiscreteObjectKeyFrame KeyTime="0">

<DiscreteObjectKeyFrame.Value>

<Visibility>Visible</Visibility>

</DiscreteObjectKeyFrame.Value>

</DiscreteObjectKeyFrame>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

<Storyboard x:Name="HideLoadingSB">

<DoubleAnimation Duration="0:0:0.2" To="0" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="LoadingOverlay"/>

<DiscreteObjectKeyFrame.Value>

<Visibility>Collapsed</Visibility>

</DiscreteObjectKeyFrame.Value>

</DiscreteObjectKeyFrame>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</Border.Resources>

<Grid>

<telerikPrimitives:RadTransitionControl x:Name="TransitionControl" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="{TemplateBinding Padding}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" Transition="{TemplateBinding Transition}" />

</StackPanel>

</Grid>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>
