Hi Jawed,
Thanks for using Syncfusion products.
We have analyzed your sample. We suggest you to set value of ‘UnobtrusiveJavaScriptEnabled’ as false in web.config. Please refer to the code snippet below to achieve this.
[Web.config]
<appSettings>
<add key="UnobtrusiveJavaScriptEnabled" value="false" /
</appSettings>
We suggest you to add the below script files in your layout.cshtml if you set UnobtrusiveJavaScriptEnabled’ as true.
<script src='@Url.Content('~/Scripts/jquery.unobtrusive-ajax.min.js')' type='text/javascript'></script>
<script src='@Url.Content('~/Scripts/jquery.validate.js')' type='text/javascript'></script>
<script src='@Url.Content('~/Scripts/jquery.validate.unobtrusive.min.js')' type='text/javascript'></script>
Please refer to the below link to download the modified sample application.
Please let us know if you have any concern.
Regards,
Ranjithkumar.
