TextBox ControlTemplate inside of a Style with InputBindings - wpf

Question

I've created a WPF Style for a TextBox with an InputBindings (KeyBinding for Enter) inside the ControlTemplate.
Style and InputBindings is working fine for my TextBoxes, but if I use this Style for my TextBoxes the TabOrder/TabStop is not working any more.
This is the style:
<Style x:Key="TextBoxTemplate" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="FontSize" Value="16"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Margin" Value="5,0,5,5"/>
<Setter Property="Width" Value="150"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<TextBox Text="{TemplateBinding Text}">
<TextBox.InputBindings>
<KeyBinding Command="{Binding EnterKeyCommand}" Key="Enter"/>
</TextBox.InputBindings>
</TextBox>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
How I add it to my TextBoxes:
<TextBox Text={Binding FirstName} Style="{StaticResource TextBoxTemplate}">
<TextBox Text={Binding LastName} Style="{StaticResource TextBoxTemplate}">
I think the problem is that I use a TextBox inside of the ControlTemplate.
But I don't know how to get running the InputBindings without the TextBox inside of the Template
Do you have any idea?
Thanks Phil

Modify your template to look like the original one plus your KeyBinding:
<Style x:Key="TextBoxTemplate" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="FontSize" Value="16"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Margin" Value="5,0,5,5"/>
<Setter Property="Width" Value="150"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"
SnapsToDevicePixels="True">
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden">
<ScrollViewer.InputBindings>
<KeyBinding Command="{Binding EnterKeyCommand}" Key="Enter"/>
</ScrollViewer.InputBindings>
</ScrollViewer>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="#FF7EB4EA"/>
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="#FF569DE5"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
