MVC3 Client side validation not working

Question

I\'m using MVC3 with Razor.
I\'ve included the following in my _Layout.cshtml:

Answer 1

Remove the Html.EnableClientValidation(); and goto your web config, and make sure you have an appSetting that looks like the below:

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

Answer 2

Try adding the following lines to your view.

HtmlHelper.ClientValidationEnabled = true;
HtmlHelper.UnobtrusiveJavaScriptEnabled = true;

Along with including jquery-1.4.4.js, jquery.validate.js, jquery.validate.unobtrusive.js

I get it to work for my app but it seems not to kick in until I put in a bad value. For example

[Required(ErrorMessageResourceType = typeof(Resources.WValidation), ErrorMessageResourceName = "TestCountRequired")]
        [Range(1, Int32.MaxValue, ErrorMessageResourceType = typeof(Resources.WValidation), ErrorMessageResourceName = "TestCountRange")]
        public int? TestCountThreshold { get; set; }

then i put in a 0 on the front-end and after that client side validation works flawlessly. I would like for validation to work for initial blank text boxes... It seems incorrect for the validation to wait until there is an attempted bad value.

Answer 3

In ASP.NET MVC 3 the jquery validation plugin is the default for performing client-side validation. So you could remove all Microsoft*.js scripts from your project. You only need the following:

<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

and remove the Html.EnableClientValidation(); call. Client validation is enabled in web.config:

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