Initializing the Validator

The following example demonstrates how to define the Validator by using the Validator TagHelper.

    @{
        var messages = new Dictionary<string, string>() { { "custom", "Please choose another Start Time." } };
        var rules = new Dictionary<string, string>() { { "custom", "customFunction" } };
    }
    <form id="ticketsForm" kendo-validator="true" kendo-messages="messages" kendo-rules="rules">
        <ul id="fieldlist">
            <li>
                <label for="fullname" class="required">Your Name</label>
                @(Html.Kendo().TextBox()
                    .Name("fullname")
                    .HtmlAttributes(new { placeholder = "Full name", required = "required", style = "width:220px" })
                )
            </li>
        </ul>
    </form>
