Property Value
Examples
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
How to: 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)/ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>

Binding Validation Sample

Remarks
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.
