Grid filter talks of enums for some reason

Radzen.Blazor Components

I don't understand why it's talking of enums. I forced the type, else it was going for equals instead of contains

Not sure I understand your case. What's the type of this property? Can you prepare runnable example demonstrating the problem?

I think i found one. those are unmapped/calculated columns. Is there any way to make a filter on those as well ?

Unmapped columns can be filtered only in-memory - i.e. if you call ToList() to your IQueryable before assigning to DataGrid Data.
