I'm not getting how exactly I can bind it from C# side of it. Can you show example of TextPredicate? The ViewModel should expose a property with the filter predicate object: public class MyViewModel { public StringFilterPredicate TextPredicate { get; private set; } public string SearchText { get { ...

Ok I've figured out how to use it, one question remained - how can I use it on HierarchicalDataTemplate to filter nested stuff?

This is a simple xaml using the CollectionFilterBehavior: <Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:b="http://schemas.microsoft.com/xaml/behaviors" xmlns:noesis="clr-namespa...

Are there any examples on how to use CollectionFilterBehavior with custom struct/type?
