How to display decimal with 3 zeros after comma, without trailing? My code is

@JurijusAmbros Then why you generate it's string representation and parse it to `decimal` if it is _already_ `decimal`? Why not just `@item.QuantityKg.ToString("N3")` instead? — Soner Gönül, Feb 10 '16 at 14:27
@JurijusAmbros Why? You _already_ give an argument in your code example as `ToString("G29")`. — Soner Gönül, Feb 10 '16 at 14:35
it gave me an error: Input string was not in a correct format. — Jurijus Ambros, Feb 10 '16 at 14:37
@JurijusAmbros Than I _strongly_ suspect your `item.QuantityKg` does not return `decimal` because `N` specifier works for `decimal` type. — Soner Gönül, Feb 10 '16 at 14:41
`String.Format("{0:N3}",item.QuantityKg)` will work with both `decimal` and `decimal?`. As a rule, `String.Format` works even if a type's specific `ToString()` doesn't allow a formatting string — Panagiotis Kanavos, Feb 10 '16 at 14:51

Since your QuantityKg is decimal? instead of decimal, you can use it's Value property and use "N" format specifier with 3 precision.

If everything is okey other than this, this should work in your case;

<td>@item.QuantityKg.Value.ToString("N3")</td>

But this throws InvalidOperationException if QuantityKg is null, so using string.Format would be better to catch this situation which generates empty string if it is null as Panagiotis mentioned.

<td>@string.Format("{0:N3}", item.QuantityKg)</td>

Or use String.Format, so that a null value will result in an empty string instead of an YSOD. It also doesn't care if the value is `decimal` or `decimal?` – Panagiotis Kanavos Feb 10 '16 at 14:49
@PanagiotisKanavos Yeah, that's seems better. Added my answer. Thanks. – Soner Gönül Feb 10 '16 at 14:54
