Stop Asp.Net Core tag helpers formatting numbers

Question

I have the situation when the asp-for formats my output, I put 5 but it displays me "5,00":

As I am in France, it puts the comas, and then does not validate the input (because of format I suppose).

Is there a way to stop asp.net formatting my numbers - leave 5 as is, no neeed to add something to it.

<label asp-for="X" class="control-label"></label>
<input asp-for="X" class="form-control" />
<span asp-validation-for="X" class="text-danger"></span>

I added

[DisplayFormat(ApplyFormatInEditMode = false)]
public decimal X { get; set; }

but this does not help.

I need to use decimals in my fields, but why it does put the comas by itself, then says "invalid format"?

Answer 1

DisplayFormat is considered when you use Html.DisplayFor, I don't know a way how is possible to enforce a number to be in a specific format it you are not changing it yourself to string, or maybe there is..

Another approach is to change the culture, US or invariant

 public ActionResult Index()
        {
            Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
            Thread.CurrentThread.CurrentUICulture =CultureInfo.InvariantCulture;
            return View();
        }

or in view (not very fancy)

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo.InvariantCulture;
Html.DisplayFor(model => model.whatever)

Still I don't think this solved the decimals problem, it will be 4.00 instead of 4,00

If you don't want decimals, on view model use int instead or decimal
