MVC 500 Internal Server Error

Question

I'm trying to send the request to controller but the console returns 500 error. What is the problem here?

Thanks in advance!

JS CODE:

 $('.delete_btn').on('click', function () { $.get("/List/Delete", { param: $(this).data('id') }, function (data) { $('#modal_window').replaceWith('<div id="modal_window">' + data + '</div>'); $('#modal_window').show(); }); }); });

Controller:

 //DELETE ITEM public ActionResult Delete(int id) { H_Table item = db_connection.H_Table.Find(id); db_connection.H_Table.Remove(item); db_connection.SaveChanges(); return RedirectToAction("Index"); }

You are passing wrong paramert name.

Change your parameter name from param to id in ajax request.

 $('.delete_btn').on('click', function () { $.get("/List/Delete", { id: $(this).data('id') }, function (data) { $('#modal_window').replaceWith('<div id="modal_window">' + data + '</div>'); $('#modal_window').show(); }); });

And your button must have data-id attribute. like this

<input type="button" class="delete_btn" value="Test" data-id="7" />

can show screenshot of your console error or network tab. and How you are getting id value.

You are performing delete operation so you need to make post or delete request and in controller you need to decorate action method by [httpPost].
