How to trace bindings in WPF?
First add the namespace to your xaml file like this:

<ResourceDictionary xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”
 xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”
 xmlns:diagnostics=”clr-namespace:System.Diagnostics;assembly=WindowsBase”>

Then add the additional magic to your Binding like this:

<ControlTemplate.Triggers>
 <DataTrigger Binding=”{Binding diagnostics:PresentationTraceSources.TraceLevel=High, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type c:ScrollViewerWithVisibilityDetectionControl}}, Path=ShowGradient}” Value=”false”>
 
 DataTrigger>
 ControlTemplate.Triggers>

Now you get detailed information in the Output window of Visual Studio.
