In this article I will explain how we can display the validation failed error messages of ASP.Net Validator controls like RequiredFieldValidator, RegularExpressionValidator, CompareValidator, RangeValidator and CustomValidator inside the ASP.Net TextBox control using jQuery.

Configuration can be done in 3 easy steps
1. Set the Display property of all Validators to Dynamic. (Display="Dynamic")
2. Set the CssClass property of all the Validators to Validators. (CssClass="Validators")
3. Finally inherit the jQuery and Float Jscript (JS) files and write the following jQuery script to apply the plugin
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/Float.js" type="text/javascript"></script>
<script type = "text/javascript">
    $(function () {
That’s all you need to do to display validation failed error messages of ASP.Net Validator inside the ASP.Net TextBox control.
