You can set the PresentationTraceSources..::.TraceLevel attached property on the following types:

• BindingBase and its derived types Binding, MultiBinding, and PriorityBinding

• BindingExpressionBase and its derived types BindingExpression, MultiBindingExpression, and PriorityBindingExpression

• ObjectDataProvider

• XmlDataProvider

TraceLevel is introduced in the .NET Framework version 3.5. For more information, see .NET Framework 3.5 Architecture.

If you run the application that contains the following XAML under a debugger, the output window provides lines of information describing the status and evaluation of the binding:

<Window
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase"
  xmlns:src="clr-namespace:SDKSample">
  <Window.Resources>
    <src:Person x:Key="myDataSource" PersonName="Joe"/>
  </Window.Resources>


...


<TextBox>
    <TextBox.Text>
        <Binding Source="{StaticResource myDataSource}" Path="PersonName"
                 diag:PresentationTraceSources.TraceLevel="High"/>
    </TextBox.Text>
</TextBox>


...


</Window>

Alternatively, you can use the PresentationTraceSources..::.SetTraceLevel static method.
