I'm getting an error while trying to load a modal window loading a different page. I was following this tutorial Implement and display jQuery Modal Popup Dialog (Window) in ASP.Net MVC Razor

However, following the tutorial the error I'm getting is this

The required anti-forgery form field "__RequestVerificationToken" is not present.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Web.Mvc.HttpAntiForgeryException: The required anti-forgery form field "__RequestVerificationToken" is not present. Source Error:

<table width="100%" bgcolor="#ffffcc">
     <tr>
         <td>
             <code></td>
     </tr>
</table>

What's the cause of this?

Hi thedonben,

It seems, you have added attribute [ValidateAntiForgeryToken] in Controller but you have failed to add @Html.AntiForgeryToken() inside the FORM in View.

@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    <table width="100%" bgcolor="#ffffcc">
       <tr>
           <td>
               <code>
           </td>
       </tr>
    </table>
}

I agree, here is the link: https://www.e-iceblue.com/Introduce/spire-office-for-net-free.html
