Enable client validation in Razor views (ASP MVC 3)
提问by Martin
I try to add client side validation using this line of code:
我尝试使用这行代码添加客户端验证：
@Html.EnableClientValidation()
@Html.EnableClientValidation()
But I keep getting this error message:
但我不断收到此错误消息：
Compiler Error Message: CS1502: The best overloaded method match for 'Microsoft.WebPages.WebPageUltimateBase.Write(Microsoft.WebPages.Helpers.HelperResult)' has some invalid arguments
编译器错误消息：CS1502：“Microsoft.WebPages.WebPageUltimateBase.Write(Microsoft.WebPages.Helpers.HelperResult)”的最佳重载方法匹配有一些无效参数
Is this working for anyone else, or is it another approach for this in ASP MVC 3?
这对其他人有用吗，还是 ASP MVC 3 中的另一种方法？

You can, instead, use the following in place of the expected line of code.
相反，您可以使用以下内容代替预期的代码行。
@(ViewContext.ClientValidationEnabled = true)
Probably an oversight in the extension methods for htmlhelper.
可能是 htmlhelper 扩展方法的疏忽。
Actually, you can use the HtmlHelper method by doing the following
实际上，您可以通过执行以下操作来使用 HtmlHelper 方法
@{ Html.EnableClientValidation(); }

Hey, in ASP.NET MVC3, there's no need to add Html.EnableClientValidation() in view page, instead, just enable the clientValidation in the webconfig file as below:
嘿，在 ASP.NET MVC3 中，不需要在视图页面中添加 Html.EnableClientValidation() ，而是只需在 webconfig 文件中启用 clientValidation ，如下所示：
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

Are you using the html <form>element on your page instead of Html.BeginFormto create your html FORM.
您是否<form>在页面上使用 html元素而不是Html.BeginForm创建 html 表单。
I had this exact same problem and worked out it was because the i was not using Html.BeginFormto create my FORM resulting in the required input attributes data-val-required="The Email field is required." data-val="true" class="input-validation-errorand the place holder for the validation was not being injected into the page even though i had the @Html.ValidationMessageFor(m => m.User.Role)inserted on my view page.
我遇到了完全相同的问题并解决了它是因为我没有Html.BeginForm用来创建我的 FORM 导致所需的输入属性data-val-required="The Email field is required." data-val="true" class="input-validation-error和验证的占位符没有被注入到页面中，即使我@Html.ValidationMessageFor(m => m.User.Role)在我的视图中插入了页。

In my case, I was not using EditorFor, but TextBoxFor!
就我而言，我没有使用 EditorFor，而是使用 TextBoxFor！
Make sure you use:
确保您使用：
<td>@Html.EditorFor(m => m.Email)</td>
