Contoh

Contoh berikut mendefinisikan Style yang akan diterapkan ke setiap TextBlock elemen. Untuk contoh lengkapnya, lihat Pengenalan Styling dan Templating Sample.

<Style TargetType="{x:Type TextBlock}">
  <Setter Property="FontFamily" Value="Segoe Black" />
  <Setter Property="HorizontalAlignment" Value="Center" />
  <Setter Property="FontSize" Value="12pt" />
  <Setter Property="Foreground" Value="#777777" />
</Style>

Contoh berikut mendefinisikan Style dengan Setteryang mereferensikan sumber daya sistem.

<Style x:Key="SystemResStyle" TargetType="{x:Type Button}">
    <Setter Property = "Background" Value= 
                       "{DynamicResource {x:Static SystemColors.ControlLightBrushKey}}"/>
    <Setter Property = "Foreground" Value= 
                       "{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
    <Setter Property = "FontSize" Value= 
                       "{DynamicResource {x:Static SystemFonts.IconFontSizeKey}}"/>
    <Setter Property = "FontWeight" Value= 
                       "{DynamicResource {x:Static SystemFonts.MessageFontWeightKey}}"/>
    <Setter Property = "FontFamily" Value= 
                       "{DynamicResource {x:Static SystemFonts.CaptionFontFamilyKey}}"/>
</Style>

Contoh berikut mendefinisikan Style untuk RepeatButton.

Contoh berikut menunjukkan Value properti yang menggunakan Binding deklarasi. Untuk contoh lengkapnya, lihat Mengikat Sampel Validasi.

<Style x:Key="textBoxInError" TargetType="{x:Type TextBox}">
  <Style.Triggers>
    <Trigger Property="Validation.HasError" Value="true">
      <Setter Property="ToolTip"
        Value="{Binding RelativeSource={x:Static RelativeSource.Self},
                        Path=(Validation.Errors)/ErrorContent}"/>
