# screen is called two times
Hi everybody,\
I have this:\
I have this:\
View:\
@model ContosoUniversity.Models.UserProfile @{ ViewBag.Title = "Edit"; }
Content for Tab 3 goes here. Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
@Html.ActionLink("Back to List", "Index")
@section Scripts { }\
and [controller action](https://www.mindstick.com/forum/34400/how-to-retrieve-form-values-in-controller-action):\
[HttpPost] public ActionResult EditPhotos(UserProfile userprofile,HttpPostedFileBase file) { if (file != null && file.ContentLength > 0) { // extract only the fielname var fileName = Path.GetFileName(file.FileName); // store the file inside ~/App_Data/uploads folder var path = Path.Combine([Server.MapPath](https://www.mindstick.com/forum/2132/server-mappath-in-asp-dot-net)("~/App_Data/uploads"), fileName); file.SaveAs(path); } if ([ModelState.IsValid](https://www.mindstick.com/forum/2002/modelstate-isvalid-contains-errors-when-using-mongodb)) { string username = User.Identity.Name; // Get the userprofile UserProfile user = db.userProfiles.FirstOrDefault(u => u.UserName.Equals(username)); // Update fields user.Image = new byte[file.ContentLength]; file.InputStream.Read(user.Image, 0, file.ContentLength); user.ImageMimeType = file.ContentType; db.Entry(user).State = EntityState.Modified; db.SaveChanges(); return Redirect(Url.Action("Edit", "Account") + "#tabs-2"); } return PartialView(userprofile); }\
it goes about tab2\
but after I put on save, the view was rendering two times, so I put a breakpoint on this line:\
`user.Image = new byte[file.ContentLength];`, I get the messagee:\
An exception of type 'System.NullReferenceException' occurred in ContosoUniversity.dll but was not handled in user code [Additional information](https://www.mindstick.com/forum/160484/error-failed-to-launch-debug-adapter-additional-information-may-be-available-in-the-output-window): Object reference not set to an [instance of an object](https://www.mindstick.com/forum/376/system-nullreferenceexception-object-reference-not-set-to-an-instance-of-an-object). file = null\
but if I after continue, then it loops again and saves the file to database. But so the first time is file = null, but if I continue the file is saved, but also the view is now showing correctly after saving the image.\

No, I just comment the form of first tab out. But I see it now like this:\
And this is the code:\
@model ContosoUniversity.Models.UserProfile@{ ViewBag.Title = "Edit";}\
Content for Tab 3 goes here. Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

@Html.ActionLink("Back to List", "Index")

@section Scripts{ }\
