Enable client validation in Razor views (ASP MVC 3)

Question

I try to add client side validation using this line of code:

@Html.EnableClientValidation()

But I keep getting this error message:

Compiler Error Message: CS1502: The best overloaded method match for 'Microsoft.WebPages.WebPageUltimateBase.Write(Microsoft.WebPages.Helpers.HelperResult)' has some invalid arguments

Is this working for anyone else, or is it another approach for this in ASP MVC 3?

Answer 1

You can, instead, use the following in place of the expected line of code.

@(ViewContext.ClientValidationEnabled = true) 

Probably an oversight in the extension methods for htmlhelper.

Actually, you can use the HtmlHelper method by doing the following

@{ Html.EnableClientValidation(); } 

Answer 2

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:

<appSettings>
  <add key="ClientValidationEnabled" value="true" />
  <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

Answer 3

this tag

     @{ Html.EnableClientValidation(false); }

must come before the

  @using (Html.BeginForm())
