  Hi

  I’m not sure if I missed it, but it doesn’t seem like C1CheckBox has support for a T parameter, so I can be specific that I want to bind to a bool instead of a nullable bool?

  It makes it difficult when I want to bind to my model which has a backend of SQL with a non-nullable bit field. I can make additional properties to do the smarts, but it seems like a lot of extra work and makes it messy especially when I have a lot of them.

  It would be nice if C1CheckBox was flexible in this way, such as MudCheckBox is with a T parameter.

  Is this possible to have as a feature?

  Thanks

  Hi James,

  Thanks for sharing your use case with us. I have forwarded your use case to the development team to have the T type parameter for the C1CheckBox.

  The internal tracking id for the same is: C1XAML-37340. I will let you know when there is more information on this from the dev team.

  Regards,

  Ankit

  Is this also possible with the C1DateTimePicker? Such that DateTime can be used for binding instead of a nullable DateTime?

  Thanks

  Hi James,

  The following code sample demonstrates an easy way for binding a valuable value type to the C1CheckBox nullable type:

  <C1CheckBox @bind-IsChecked:set="v=>IsEnabled = v.Value"
              @bind-IsChecked:get="@((bool?)IsEnabled)">
  </C1CheckBox> CheckBox
  
  
  @code {
      public bool? IsEnabled { get; set; } = null;
  }

  You could refer to the following documentation: https://learn.microsoft.com/en-us/aspnet/core/blazor/components/data-binding?view=aspnetcore-9.0

  For the C1DateTimePicker, I believe you could initially set the binding value to be non-nullable DateTime, and thus can be used in this way. If this doesn’t satisfy your use case, I request you to kindly do share your use case so that we could have better understanding of your use case and could help you accordingly.

  Regards,

  Ankit

  Hi Ankit.

  Thanks. I will have a look at your sample. I appreciate the response.
  
  You linked the .net9 documentation, but it looks to be available in .net8 too which is good.
  
  I’ll give it a shot and see how I go.

  Thanks.
