Visual Basic (Usage)

Remarks

A Style contains a collection of one or more Setter objects. Each Setter has a Property and a Value. The Property is the property of the element the style is applied to. The Value is the value that is applied to the property.

You must specify both the Property and Value properties on a Setter or an exception is thrown.

Examples

The following example creates two styles: one for a TextBlock and one for a TextBox. The style for the TextBlock sets the Foreground, FontSize, and VerticalAlignment properties. The style for the TextBox sets the Width, Height, Margin, Background, and FontSize properties. Each style is applied to two instances of a control to create a uniform appearance for each TextBlock and TextBox.

XAML

<StackPanel>
  <StackPanel.Resources>
    <!--Create a Style for a TextBlock to specify that the
              Foreground equals Navy, FontSize equals 14, and
              VerticalAlignment equals Botton.-->
    <Style TargetType="TextBlock" x:Key="TextBlockStyle">
      <Setter Property="Foreground" Value="Navy"/>
      <Setter Property="FontSize" Value="14"/>
      <Setter Property="VerticalAlignment" Value="Bottom"/>
    </Style>

    <!--Create a Style for a TextBlock that specifies that
              the Width is 200, Height is 20, Margin is 4,
              Background is LightBlue, and FontSize is 14.-->
    <Style TargetType="TextBox" x:Key="TextBoxStyle">
      <Setter Property="Width" Value="200"/>
      <Setter Property="Height" Value="30"/>
      <Setter Property="Margin" Value="4"/>
      <Setter Property="FontSize" Value="14"/>
      <Setter Property="Background">
        <Setter.Value>
          <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5">
            <GradientStop Color="White" Offset="0.0"/>
            <GradientStop Color="LightBlue" Offset="0.5"/>
            <GradientStop Color="Navy" Offset="1"/>
          </LinearGradientBrush>
        </Setter.Value>
      </Setter>
    </Style>
  </StackPanel.Resources>

  <!--Apply the TextBlockStyle and TextBoxStyle to each 
          TextBlock and TextBox, respectively.-->
  <StackPanel Orientation="Horizontal">
    <TextBlock Style="{StaticResource TextBlockStyle}">
              First Name:
          </TextBlock>
    <TextBox Style="{StaticResource TextBoxStyle}"/>
  </StackPanel>
  <StackPanel Orientation="Horizontal">

    <TextBox Style="{StaticResource TextBoxStyle}"  
                   Margin="6,4,4,4"/>
