Hi I think here is the problem with your code. you have taken the three images (image1 image2 inage3) and while edit your code detecting only one file. for multiple file upload check the code http://www.aspdotnet-pools.com/2014/06/multiple-file-upload-with-aspnet-mvc-c.html Now expecting you have only on e image public ActionResult Edit([Bind(Include = IdImage1Image2Image3NameQuantityInStockCreatedDateTimeModifiedDateTimeCreatedByModifiedBy)] tbl_Product tbl_Product HttpPostedFileBase file) { if (ModelState.IsValid) { db.Entry(tbl_Product).State = EntityState.Modified; DateTime saveTime = DateTime.Now; if (tbl_Product.CreatedDateTime == null && tbl_Product.ModifiedDateTime == null) { tbl_Product.CreatedDateTime = saveTime; tbl_Product.ModifiedDateTime = saveTime; } if(file.FileName!=null) { string filename = System.IO. Path .GetFileName(file.FileName); /*Saving the file in server folder*/ file.SaveAs(Server.MapPath( ~/Images/ + filename)); string filepathtosave = Images/ + filename; tbl_Product.image1= filepathtosave; } else { tbl_Product.image1=image1; } db.SaveChanges(); return RedirectToAction(Index); } return View(tbl_Product); }

Hi While reteriving the data from database. just store the image data into the variable and on the post check weather user have uploaded any new image or not. if no then assign the old image url and save it.
