c# - ASP .NET MVC Disable Client Side Validation at Per-Field Level

Question

I'm using ASP .NET MVC 3 with Data Annotations and the jQuery validate plugin.

Is there a way to mark that a certain field (or certain data annotation) should only be validated server-side?

I have a phone number field with a masking plugin on it, and the regular expression validator goes crazy on the user's end. The regex is only a fail-safe (in case someone decides to hack the javascript validation), so I don't need it to run on the client side. But I'd still like the other validation to run client side.

I'm not sure if this solution works on MVC3. It surely works on MVC4:

You can simply disable client side validation in the Razor view prior to render the field and re-enable client side validation after the field has been rendered.

Example:

<div class="editor-field">
    @{ Html.EnableClientValidation(false); }
    @Html.TextBoxFor(m => m.BatchId, new { @class = "k-textbox" })
    @{ Html.EnableClientValidation(true); }
</div>

Here we disable client side validation for the BatchId field.

Also I have developed a little helper for this:

public static class YnnovaHtmlHelper
{
    public static ClientSideValidationDisabler BeginDisableClientSideValidation(this HtmlHelper html)
    {
        return new ClientSideValidationDisabler(html);
    }
}

public class ClientSideValidationDisabler : IDisposable
{
    private HtmlHelper _html;

    public ClientSideValidationDisabler(HtmlHelper html)
    {
        _html = html;
        _html.EnableClientValidation(false);
    }

    public void Dispose()
    {
        _html.EnableClientValidation(true);
        _html = null;
    }
}

You will use it as follow:

<div class="editor-field">
    @using (Html.BeginDisableClientSideValidation()) {
        @Html.TextBoxFor(m => m.BatchId, new { @class = "k-textbox" })
    }
</div>

If anyone has better solutions please let me know!

Hope this help.
