ASP.NET MVC数据注解属性设置范围从另一个属性值 [英] ASP.NET MVC data annotations attribute Range set from another property value

问题描述

您好我在我的Asp.net MVC模式具有以下

Hi I have following in my Asp.net MVc Model

TestModel.cs

TestModel.cs

public class TestModel
{      
public double OpeningAmount { get; set; }

[Required(ErrorMessage="Required")]
[Display(Name = "amount")]
[Range(0 , double.MaxValue, ErrorMessage = "The value must be greater than 0")]
public string amount { get; set; }

}

现在从我的控制器OpeningAmount是分配。

Now from my controller "OpeningAmount " is assign .

Finaly当我提交表单我要检查量一定比OpeningAmonut更大。所以要设置动态范围像

Finaly when I submit form I want to check that "amount" must be greater than "OpeningAmonut" . so want to set Range dynamically like

[Range(minimum = OpeningAmount , double.MaxValue, ErrorMessage = "The value must be greater than 0")]

我不希望只使用jQuery的或JavaScript，因为它仅检查客户端，以便尽可能我可以设置范围属性最小动态比这将是巨大的。

I do not want to use only Jquery or javascript because it will check only client side so possible I can set Range attribute minimum dynamically than it would be great for.

推荐答案

有没有内置的属性，它可以与性能之间的依赖性工作。

There's no built-in attribute which can work with dependence between properties.

所以，如果你想与属性的工作，你必须编写自定义的。

So if you want to work with attributes, you'll have to write a custom one.

另一个解决方案是一个验证库的工作，比如（非常漂亮） FluentValidation

Another solution would be to work with a validation library, like (the very nice) FluentValidation .
