I am trying to Enable/Disable a group of time inputs in Blazor based on a checkbox ; while for inputs of type button>
To disable elements you should use the disabled attribute.
I've modified your code a bit and this will do what you're after. Blazor will automatically add or remove the disabled attribute based on the IsDisabled value.
You should use the disabled attribute on your button as well. It's a much better practice.
@code{
protected bool IsDisabled { get; set; }
}
You can still combine this with applying a CSS class for styling the disabled element. It's up to you.
