For me following code work

$(function () {
    debugger;
    document.getElementById("FormId").addEventListener("submit", function (e) {
        debugger;
        if (ValidDateFrom()) { // Check Validation 
            var form = e.target;
            if (form.getAttribute("enctype") === "multipart/form-data") {
                debugger;
                if (form.dataset.ajax) {
                    e.preventDefault();
                    e.stopImmediatePropagation();
                    var xhr = new XMLHttpRequest();
                    xhr.open(form.method, form.action);
                    xhr.onreadystatechange = function (result) {
                        debugger;
                        if (xhr.readyState == 4 && xhr.status == 200) {
                            debugger;
                            var responseData = JSON.parse(xhr.responseText);
                            SuccessMethod(responseData); // Redirect to your Success method 
                        }
                    };
                    xhr.send(new FormData(form));
                }
            }
        }
    }, true);
});

In your Action Post Method, pass parameter as HttpPostedFileBase UploadFile and make sure your file input has same as mentioned in your parameter of the Action Method. It should work with AJAX Begin form as well.

Remember over here that your AJAX BEGIN Form will not work over here since you make your post call defined in the code mentioned above and you can reference your method in the code as per the Requirement

I know I am answering late but this is what worked for me
