I have in the fact copied the code of Login page in the ASP.NET MVC application template (provided with VS). In the original template, client side validation is working but when I copy all the connected code I get only server side validation (no red fields, post back even if data are incorrect).
Here is my model code:
public class LogOnModel {
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[Display(Name = "Remember me?")]
public bool RememberMe { get; set; }
}
Here is the controller:
public class LogOnController : Controller
{
public ActionResult Index() {
return View();
}
[HttpPost]
public ActionResult Index(LogOnModel model)
{
if (ModelState.IsValid) {
return RedirectToAction("Index", "Games");
}
return View(model);
}
}
And this is the View:
<%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage<PuzzleHunter.Web.Models.LogOnModel>" MasterPageFile="~/Views/Shared/SiteMasterPage.master" %>
<asp:Content runat="server" ID="Content" ContentPlaceHolderID="MainContent">
<script src="<%: Url.Content("~/Scripts/jquery.validate.min.js") %>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js") %>" type="text/javascript"></script>
<% using (Html.BeginForm()) { %>
<%: Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.") %>
<div>
<fieldset>
<legend>Account Information</legend>
<div class="editor-label">
<%: Html.LabelFor(m => m.UserName) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(m => m.UserName) %>
<%: Html.ValidationMessageFor(m => m.UserName) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(m => m.Password) %>
</div>
<div class="editor-field">
<%: Html.PasswordFor(m => m.Password) %>
<%: Html.ValidationMessageFor(m => m.Password) %>
</div>
<div class="editor-label">
<%: Html.CheckBoxFor(m => m.RememberMe) %>
<%: Html.LabelFor(m => m.RememberMe) %>
</div>
<p>
<input type="submit" value="Log On" />
</p>
</fieldset>
</div>
<% } %>
I also have following lines in my Web.config
file:
<appSettings>
<add key="ClientValidationEnabled" value="true"/>
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>
</appSettings>
I include here the output html code:

For comparison this is the output of VS MVC template where client side validation is working:
<!DOCTYPE html>
<html>
<head><title>
Log On
</title><link href="../Content/Site.css" rel="stylesheet" type="text/css" />
<script src="/Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
</head>
<body>
<div class="page">
<div id="main">
<script src="/Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="/Scripts/jquery.validate.unobtrusive.min.js" type="text/javascript"></script>
<form action="/Account/LogOn" method="post">
<div>
<fieldset>
<legend>Account Information</legend>
<div class="editor-label">
<label for="UserName">User name</label>
</div>
<div class="editor-field">
<input data-val="true" data-val-required="The User name field is required." id="UserName" name="UserName" type="text" value="" />
<span class="field-validation-valid" data-valmsg-for="UserName" data-valmsg-replace="true"></span>
</div>
<div class="editor-label">
<label for="Password">Password</label>
</div>
<div class="editor-field">
<input data-val="true" data-val-required="The Password field is required." id="Password" name="Password" type="password" />
<span class="field-validation-valid" data-valmsg-for="Password" data-valmsg-replace="true"></span>
</div>
<div class="editor-label">
<input data-val="true" data-val-required="The Remember me? field is required." id="RememberMe" name="RememberMe" type="checkbox" value="true" /><input name="RememberMe" type="hidden" value="false" />
<label for="RememberMe">Remember me?</label>
</div>
<p>
<input type="submit" value="Log On" />
</p>
</fieldset>
</div>
</form>
</div>
</div>

</html>
You need to add the following before the FORM
begins:
<% Html.EnableClientValidation();%>
Also, ensure you have this script referenced:
<script src="<%=Url.Content("~/Scripts/MicrosoftMvcJQueryValidation.js")%>"
As well as jQuery itself.
The answer is: <script src="<%: Url.Content("~/Scripts/jquery-1.4.4.min.js") %>" type="text/javascript"></script>
was not in my Master page header tag at first. When I added it it should work but it did not for next 4 hours.
Probably because Firefox kept showing me the old version with no reference to <script src="<%: Url.Content("~/Scripts/jquery-1.4.4.min.js") %>" type="text/javascript"></script>
. Or... Accept goes to the only answer that is not mine there.
