Async validation is not updating after a delay

I had the same issue in general on Blazor with a text box, they are fixing this in 3.1 https://github.com/aspnet/AspNetCore/issues/11914. There is a workaround and I have confirmed that textboxs on 3.1 textboxes work without the workaround. I'm doing a trial of Telerik's Blazor components and noticed the same validation issue existed so I had to put back in the workaround to fix it. It would be nice if this workaround wasn't required.

Hello Anne,

I have reviewed this again and I think I had missed the concept of this request. I have logged it for implementation that we should also handle the EditContext.OnValidationStateChanged event and call StateHasChanged(), which should, let async validation work as well, and it should not break anything existing.

I moved this item to the Feedback portal so you can Follow it. Here's a link where you can subscribe for notifications: https://feedback.telerik.com/blazor/1441550-async-validation-is-not-updating-after-a-delay.

Hi Anne,

Can you confirm for me exactly what type of validation you are using? Can you observe such a problem with code based on this article: https://docs.telerik.com/blazor-ui/common-features/input-validation?

I am asking because at the moment we test and support only the standard (built-in) data annotations validation, and the FluentValidator is a custom solution that we have not tested or integrated with. My point being that it seems to me that you are using the FluentValidation package and I need to know the exact setup so I can see if there is anything we can do about it.
