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”>
<!– setters here –>
</DataTrigger>
</ControlTemplate.Triggers>
Now you get detailed information in the Output window of Visual Studio.
