Display decimal without trailing zeros in MVC view

Question

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

<td>@decimal.Parse(item.QuantityKg.ToString()).ToString("G29")</td>

@JurijusAmbros Then why you generate it's string representation and parse it to decimal if it is already decimal? Why not just <td>@item.QuantityKg.ToString("N3")</td> instead? — Soner Gönül

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

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?

@PanagiotisKanavos Yeah, that's seems better. Added my answer. Thanks.
