Property Value

A static RelativeSource.

Three of the four RelativeSourceMode values, PreviousData, Self, or TemplatedParent, can produce a RelativeSource that is wholly static, containing no unique private values. All uses of the static property can share the same object, eliminating the need to allocate separate objects for each use. Therefore, using the static property reduces memory usage.

The following example shows a style trigger that creates a ToolTip that reports a validation error message. The value of the setter binds to the error content of the current TextBox (the TextBox using the style) using the RelativeSource property. See Implement Binding Validation for more information on this example.

<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)[0].ErrorContent}"/>
    </Trigger>
  </Style.Triggers>
</Style>
