On the Grid filtering demo page (Blazor DataGrid Component - Simple Filter Mode with Menu | Free UI Components by Radzen) the default filtering for string column (eg: Customer.CustomerName) is Contains. But from the filter type selector I can not select Contains. That is not listed. So if I change the filtering to Equals, I cannot change back to Contains. (DoesNotContains also missing)
Will be fixed in our next update before the end of the week.
