속성 값

A RelativeSource object specifying the relative location of the binding source to use. The default value is null 참조(Visual Basic의 경우 Nothing).

This property is commonly used to bind one property of an object to another property of the same object, or to define a binding in a style or template.

By default, bindings inherit the data context specified by the DataContext property, if one has been set. However, the RelativeSource property is one of the ways you can explicitly set the source of a Binding and override the inherited data context. For more information, see How to: Specify the Binding Source.

The Binding.ElementName and Binding.Source properties also enable you to set the source of the binding explicitly. However, only one of the three properties, ElementName, Source, and RelativeSource, should be set for each binding, or a conflict can occur. This property throws an exception if there is a binding source conflict.

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. For more information on this example, see Implement Binding Validation.

<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>
