How to Pass and Retrieve a Complete Model Object Using FormData in MVC?

Passing and Retrieving Model Data Using FormData in MVC

Passing a complete model object through FormData can be beneficial when working with complex data in your web application. Here's how you can achieve this:

JavaScript:

Use the FormData() constructor with the form element to serialize the model:

var formdata = new FormData($('form').get(0));

This will capture the data from the form controls, including any files attached through .

AJAX Request:

Configure your AJAX request with the appropriate settings:

$.ajax({
  url: '@Url.Action("YourActionName", "YourControllerName")',
  type: 'POST',
  data: formdata,
  processData: false,
  contentType: false,         
});

Controller:

In your controller, create an action to handle the request:

[HttpPost]
public ActionResult YourActionName(YourModelType model)
{
}

MVC will automatically bind the serialized model data to an instance of YourModelType. If the model contains a property for HttpPostedFileBase, your controller action can include a parameter for it as well.

Additional Data:

If you need to include additional data that is not present in the form, you can use the append() method on the FormData object:

formdata.append('someProperty', 'SomeValue');

By following these steps, you can transfer a complete model object through FormData during an AJAX request and conveniently retrieve it in the corresponding controller action for further processing.
