ASP.NET MVC Client Validation with jQuery using Html.ValidationMessage?

ASP.NET MVC Client Validation with jQuery using Html.ValidationMessage?

this will help You could write a ton of code to do this. Or you could just use xVal, which is free and does exactly this, plus much more. Put value annotations on your .NET types, add a couple of simple things to your aspx, and you get jQuery validation for free. Plus it comes with providers for popular frameworks, and it's very customizable in case you need more complex validation.
I see no need to reinvent the wheel here.

With these it helps I'm having trouble getting client validation to work on a web form. I'm including .js files and have the relevant lines in web.config, but data validation doesn't get put into the HTML on the client side. , You should wrap these code in Html.BeginForm
code :
@using (Html.BeginForm()) {
    <div class="conLine">
    @Html.LabelFor(m=> m.url):  @Html.TextBoxFor(m => m.url) 
    @Html.ValidationMessageFor(m => m.url)
    </div>
    <div class="conLine">
    @Html.LabelFor(m=> m.email):  @Html.TextBoxFor(m => m.email) 
    @Html.ValidationMessageFor(m => m.email)
    </div>
}

To fix the issue you can do Make sure that this dropdown is placed inside a form. For client side validation to work you need a form context or the Html helpers won't emit any HTML5 data-* attributes:
code :
@using (Html.BeginForm())
{
    @Html.LabelFor(xModels => xModels.SelectedChannelID)
    @Html.DropDownListFor(
        x => x.SelectedChannelID, 
        Model.ChannelSelectList, 
        "--Select Channel--", 
        new Dictionary<string, object> { { "id", "ChannelsDDL" } }
    )
    @Html.ValidationMessageFor(xModels => xModels.SelectedChannelID)    
    <button type="submit">OK</button>
}
@{
    ViewContext.FormContext = new FormContext();
}

@Html.LabelFor(xModels => xModels.SelectedChannelID)
@Html.DropDownListFor(
    x => x.SelectedChannelID, 
    Model.ChannelSelectList, 
    "--Select Channel--", 
    new Dictionary<string, object> { { "id", "ChannelsDDL" } }
)
@Html.ValidationMessageFor(xModels => xModels.SelectedChannelID)    
<select data-val="true" data-val-number="The field Channel:  must be a number." data-val-required=" Channel is required" id="ChannelsDDL" name="SelectedChannelID">
    ...
</select>

it fixes the issue Fuel just outputs HTML5 validation rules with the form elements. It's up to the browser to support them.
Google Chrome (16+) Mozilla Firefox (8+) and Internet Explorer (10+)
