自定义的正前pression没有验证在客户端 [英] Custom Regular Expression not validating on the client side

问题描述

我有建立一个自定义属性在客户端验证了积极的十进制值。问题是，当我直接应用常规前pression的财产，它工作正常，但是当我使用自定义属性，这是行不通的。

工作方式：

  [RegularEx pression（@^（？0？（0？0）？$）（[0-9] {0,3}（[ 0-9] {1,2}）？）？$的ErrorMessage =Largurainválida。）
    [必需（的ErrorMessage =Larguraobrigatória。）
    [显示（NAME =Formato Aberto）]
    公共小数SizeOpenedWidth {搞定;组; }
 

自定义属性：

 公共类PositiveDecimalAttribute：RegularEx pressionAttribute
{
    公共PositiveDecimalAttribute（）：基地（^（？！0（0 0）$）（[0-9] {0,3}（[0-9] {1,2}））？？？？？ $）{}
}
 

集成在属性：

  [PositiveDecimal（的ErrorMessage =Largurainválida。）
    [必需（的ErrorMessage =Larguraobrigatória。）
    [显示（NAME =Formato Aberto）]
    公共小数SizeOpenedWidth {搞定;组; }
 

在第二个，客户端验证presents错误消息：

 现场Formato Aberto必须是数字。
 

我是否需要新的属性在客户端验证集成？

解决方案

您需要的Global.asax 注册您的属性。在其的Application_Start（）方法，添加以下code：

<$p$p><$c$c>DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(PositiveDecimalAtt‌​ribute), typeof运算（RegularEx pressionAttributeAdapter））;

I have build a custom attribute to validate on the client side a positive decimal value. The problem is that when I apply the regular expression directly to the property, it works fine, but when I use the custom attribute, it does not work.

Working mode:

    [RegularExpression(@"^(?!0?(,0?0)?$)([0-9]{0,3}(,[0-9]{1,2})?)?$", ErrorMessage = "Largura inválida.")]
    [Required(ErrorMessage = "Largura obrigatória.")]
    [Display(Name = "Formato Aberto")]
    public decimal SizeOpenedWidth { get; set; }

Custom Attribute:

public class PositiveDecimalAttribute : RegularExpressionAttribute
{
    public PositiveDecimalAttribute() : base("^(?!0?(,0?0)?$)([0-9]{0,3}(,[0-9]{1,2})?)?$") { }
}

Integrated in the property:

    [PositiveDecimal(ErrorMessage = "Largura inválida.")]
    [Required(ErrorMessage = "Largura obrigatória.")]
    [Display(Name = "Formato Aberto")]
    public decimal SizeOpenedWidth { get; set; }

In the second one, client side validation presents the error message:

The field Formato Aberto must be a number.

Do I need to integrate the new attribute on the client side validation?

解决方案

You need to register your attribute in global.asax. In its Application_Start() method, add the following code:

DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(PositiveDecimalAtt‌​ribute), typeof(RegularExpressionAttributeAdapter));
