[Question] How to use ReactiveValidationObject and INotifyDataErrorInfo in WPF about reactiveui.validation HOT 6 CLOSED

Is there another way to use INotifyDataErrorInfo using only ReactiveUi bindings?

No. The INotifyDataErrorInfo is only supported via XAML binding, it doesn't support BindValidation. But you can make your own extension method like here for WPF.

If i remember correct, the reason is because RxUI has it's own binding mechanism.
I also think there was idea to make platform depended libs like ReactiveUI.Validation.WPF to support it, but im not sure.

from reactiveui.validation.

We listen and do the setting of the property ourselves in RxUI bindings, and don't use the inbuilt classes that WPF provides, it's more multi platform aware that way.

The downside is that INotifyDataErrorInfo relies on WPF inbuilt binding classes.

There's nothing stopping you from using the inbuilt WPF Bind with RXUI, we abstract it out into a ICreatesObservable interface so you could make sure of those classes behind the scenes.

Might be a future WPF/UWP package feature.

Thank you all for clarification.

@glennawatson what do you think about to add info that INotifyDataErrorInfo requires classic binding/connecting to build-in WPF mechanism? I can make PR with it but first I would like to know if this makes sense.

Documentation updated, so I'm closing this. Thank you all for your time in clarification and PR review.
