Anonymous ValidationMessages

[Chris-Mingay]

This is a crude example but:

The first rule is specific to a field of a command (Title) so in the front end I show this by using

<ValidationMessage For="() => Command.Title" />

The second rule is NOT specific to a field so I would like to display it at the top of the form, is there a way to do this?

Initial thoughts were I could do something like <ValidationMessage For="() => Command" /> because it matches the Expression of the rule. That didn't work.

My second thought was to use <ValidationSummary/> however, this shows all of the errors, I just want to show "unlinked" errors at the top of the form.

Any ideas?

Thanks again

Chris

Hi Chris,

I don't think this is possible with Blazor's forms and validation system as-is. I think the key part is the Validation Store, it holds a key which corresponds to a property on the form model and a list of errors for that key. The issue with what you're attempting is that there would be an error but it wouldn't belong to anything.

Cheers Chris, I guess that's what I am after then really, being able to filter out the messages that don't belong to anything and show them at the start. I guess that might be possible somewhere? Either way I think this falls under an EditForm issue more than anything to do with FluentValidation so I'll see what I can find!
