Validation red border always visible after validation

[grizoood]

Hello, I am having a problem using validations. The validation border is still present after performing the validation of the property. I work with WPF

I create a shopping list (with 2 properties: start and end). For each race I pass the shopping list as a parameter.

My goal is to do this:

Start end
0 10
10 20
21 30
31 40
...

When I change a property, I run the check on all of the shopping list properties.

My problem is that the border still appears even though the property returned ValidationResult.Success

I attach the test project.

Please can you help me

Hi @grizoood, this isn't a forum for general WPF questions. This is for the Windows Community Toolkit which is a set of helpers and controls for UWP and the Windows App SDK/WinUI 3. If you're using the MVVM Toolkit and this is an issue with that, their repo is here.

I'd suggest posting on stack overflow or trying the C# Community discord server and asking in their #gui channel. If you think there's an issue with WPF itself, their GitHub repo is here.
