DataAnnotations: DisplayFormat not being honored

本文关键字：being honored not DisplayFormat DataAnnotations | 更新日期: 2023-09-27 18:16:19

这两种方法我都试过了:

[Display(Name = "Contract Value")]
[DisplayFormat(DataFormatString = "{0.##}")]
public decimal ContractValue { get; set; }

: 

[Display(Name = "Contract Value")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0.##}")]
public decimal ContractValue { get; set; }

视图:

@Html.LabelFor(x => contractInfoModel.ContractValue)
@Html.TextBoxFor(x => contractInfoModel.ContractValue, new { maxlength = "100" })

如果我这样做，它工作。但是我不想这样做:

<input type="text" name="@Html.NameFor(x=>contractInfoModel.ContractValue)" id="@Html.IdFor(x=>contractInfoModel.ContractValue)" value="@Model.ContractInfoM.ContractValue.ToString("0.##")" class="numeric" maxlength="10" />

显示名称工作得很好。但它仍然显示了小数点后四位。我做错了什么?

谢谢!

找到了:

根据设计，在TextBoxFor中不支持DisplayFormat。所以不用这个:

@Html.TextBoxFor(x => contractInfoModel.ContractValue, new { maxlength = "10" })

我这样做了:

@Html.EditorFor(x => contractInfoModel.ContractValue, new { maxlength = "10" })

效果很好
