Maui VS XamlBehaviorsWpf

There's a host of "community toolkits" for various XAML frameworks and it's possible I"m a bit out of date and behaviors moved to one of those. I can't find one for WPF, but for example this is the MAUI one and it has an extensive collection of behaviors. (Those only work in MAUI though, "for reasons" there's not one consistent way to cross-framework develop behaviors.)

Im speaking of https://github.com/CommunityToolkit/Maui

It won't work. You'll probably need this one instead: https://github.com/CommunityToolkit/Maui

It looks like the best modern answer is eventually those libraries moved to a NuGet package, Microsoft.Xaml.Behaviors.Wpf. The namespaces might've been shuffled around, so you might have to update the schema reference in your XML, but it seems like that one is the correct one.

u/KryptosFR if you do end up using Behaviors, the current official NuGet package is https://github.com/Microsoft/XamlBehaviorsWpf - but the official documentation isn't excellent so you may need to learn from 3rd party sources like the one that Spider shared.

See https://github.com/microsoft/XamlBehaviorsWpf and https://stackoverflow.com/questions/10683504/use-of-behavior-in-wpf-mvvm. In general, you can extract logic "Invoke bound command when text changed" to a separate logic unit called behavior. After that, you can add your behavior to the element behavior collection attached property. When behavior is added, it "attaches" to the element, and it is allowed to use events in behaviors. Also you can define command attached property so that you can specify what you'd like to invoke. After that, in behavior in text changed handler, you can invoke your command.

The short answer is usually people who use WPF adopt an MVVM framework and those define the Behavior class. This is the MS package for WPF though if you use some MVVM framework you should probably use the one it provides instead. It seems like you found that one.

There is an official library for that among other things.

The following XAML shows how to use the wrapper. The dependency property NotifyRequest is bound to the property mentioned above. Each routed event is bound to the corresponding routed command with Xaml.Behaviors.WPF.
