JsonRequestBehavior.AllowGet);

view

$(document).ready(function() {
                $('#fileupload').fileupload({
                    dataType: 'json',
                    url: '/Admin/Image/UploadFiles',
                    autoUpload: true,
                    done: function (e, data) {
                        alert(data.message); //showing undefined
                        if (data.message== 'success') {
                            alert(data.message);
                            window.location = "www.google.com";
                        }
                    },
                    fail: function(e, data) {
                        console.write(data.errorThrown);
                    }
                })

what if you alert the whole data returned? is it undefined too? — qamar, May 13 '14 at 15:06
Use your debuggers (e.g. Chrome tools or whatever). Make the ajax call, look in the Network pane for the response. Is the response code 200? Have have look at the response, has it returned json data? — Dylan Morley, May 13 '14 at 15:09

Do you want the complete or success property? You are confusing the xhr object's .done() with ajax setup property complete: or success: I think.

Done's second parameter is a status, not the data.

Try this instead

 $(document).ready(function() {
            $('#fileupload').fileupload({
                dataType: 'json',
                url: '/Admin/Image/UploadFiles',
                autoUpload: true,
                success: function (data, status, xhr) {
                    alert(data.message); 
                    if (data.message== 'success') {
                        alert(data.message);
                        window.location = "www.google.com";
                    }
                }
            })
