The RadzenRequiredValidator is implemented automatically during code generation by Radzen Blazor Studio 1.5.2.
Unfortunately, all these checkboxes cannot be save to database as checked=bit set=true to SQL Server, since the RadzenRequiredValidator fires once a checkbox is not checked.
In a correct way, the RadzenRequiredValidator should fire only, as long as the check-box is in a unset-state, equal to NULL.
I have tried many different configurations. However, with no success.
SQL Field, for example:
ALTER TABLE [dbo].[AspNetUsers] ADD CONSTRAINT [DF_AspNetUsers_PhoneNumberConfirmed] DEFAULT ((0)) FOR [PhoneNumberConfirmed]
<RadzenCheckBox @bind-Value="@aspNetUser.PhoneNumberConfirmed" Name="PhoneNumberConfirmed" />
