将ControlTemplate值绑定到样式属性

Question

I have a ControlTemplate for my custom button.

Im trying to bind the <Border.Background> in the ControlTemplate to the Styles Background property.

XAML

<ControlTemplate x:Key="NumberButtonControlTemplate" TargetType="Button" >
    <Border x:Name="Border">
        <Border.Background>
            <SolidColorBrush Color="{TemplateBinding Background}" />
        </Border.Background>
    </Border>
</ControlTemplate>



<Style x:Key="NumberButtonStyle" TargetType="Button">
    <Setter Property="Template" Value="{StaticResource NumberButtonControlTemplate}" />        
    <Setter Property="Background" Value="MediumSpringGreen" />
    <Setter Property="Height" Value="80" />
</Style>

How do I make the ControlTemplate BorderBackground Property get the value of the Style Background ?

What I have done above is right, is there something Im missing ?

Answer 1

The Background property on Button (and on Border ) is of type Brush but you're attempting to use it as a Color . Use this instead:

<Border x:Name="Border" Background="{TemplateBinding Background}"/>
