Hello, i'm trying to had a decimal number in my textbox but i can't add a . or , to write my decimal number. here is the declaration of my property that i bind to my textbox.

private readonly SymmetricRoll _symmetricRoll;
public double RollPosition
{
    get => _symmetricRoll.RollPosition;
    set => SetProperty(_symmetricRoll.RollPosition, value, _symmetricRoll, (symmRoll, newValue) => symmRoll.RollPosition = newValue);
}

private readonly SymmetricRoll _symmetricRoll;
public double RollPosition
{
    get => _symmetricRoll.RollPosition;
    set => SetProperty(_symmetricRoll.RollPosition, value, _symmetricRoll, (symmRoll, newValue) => symmRoll.RollPosition = newValue);
}

Do i need to link my textbox to a string and then i parse this string to affect the value to RollPosition ?

Have you considered using a converter directly on your binding? You can keep the property type as double And have the textbox receive a formatted string

yeah i've already thougth about this possibility but it looks a bit weird to me to do a converter in order to take input for double

Well one way or another you'll have to have some conversion logic to take a string and format it into a double. Even if you end up going with a custom control So I say that a converter is fine
