How to mark true only one check every time?

Hello gustavobp,

You would need to use a custom type converter.

See the reference sample linked below in the regions 'Use Case #2: Disable/enable properties based on secondary input'.

Hello Boys!!!
I need to make sure that only one of the 2 checks can be true at a time, that is, if I click on one check, the other is automatically deactivated. This is because it makes no sense to have both conditions activated at the same time to preserve the logic of the inputs. How can I do it? Do you have any practical and functional example of how it should be done? Thank you so much!!!

[Display(Name = "FAST EMA ABOVE SLOW EMA", Order = 7, GroupName = "Block 1: Condiciones de entrada")]
public bool ActivarEma9OverEma20Condition { get; set; } = true; // Checkbox para activar que la ema de 9 debe ser mayor a la ema de 20 para abrir una operacion
