# Overview

FormValidation is one of the best validation library for JavaScript. For more info see the official siteand the Github repository.

# Usage

FormValidation's Javascript bundles are globally included in all pages.

    <link href="assets/plugins/global/plugins.bundle.css" rel="stylesheet" type="text/css"/>
    <script src="assets/plugins/global/plugins.bundle.js"></script>

# Initialization

- FormValidation is primarily initialized via Javascript by adding a unique `id`to the `form`element.
- Important Add `fv-row`CSS class to the input group to identify the input field that requires FormValidation.
- Please refer to the official documentationfor all validation options available.

# Integrating with ASP.Net

Since ASP.Net changes the field name when rendering the controls, you have to use `<%= control.UniqueID %>` as the name of fields. For more information, please refer to the official documentation.
