This tutorial will explore different techniques for submitting forms in ASP.NET MVC, including traditional form submissions, AJAX requests, and more.

What is Form Submit (Submission)?

The user fills in the form/page and sends the entered details to the server. In the end, we want information; and the user details should be saved on the server.

Following are the ways to submit the form.

  • @Html.BeginForm with hard-code Action.
  • @Ajax.BeginForm with hard-code Action.
  • HTML Input Submit Button using FormAction, FormMethod attributes.
  • Using jQuery set form Action property.
  • Using jQuery AJAX with FormData.
  • Using jQuery AJAX with serializeFormJSON.

This method or way is not good for more fields forms because we have to assign manually the value of form control to FormData object and property.
