  1. POSystem.Web.HttpPostedFileWrapper string is being saved instead of file pathname
    text
    copied!<p>This used to work fine, but now the code is not saving the pathname to the <code>SitePlan</code> and <code>SiteImage</code> fields. If I debug everything looks fine and <code>SitePlan</code> and <code>SiteImage</code> contain pathnames to the uploaded files (i.e. ~/UploadedFiles/20110210104108SiteImage77.jpg). But once save in the <code>SitePlan</code> and <code>SiteImage</code> fields is the string value "System.Web.HttpPostedFileWrapper".</p> <p>Struggling with this since its saves fine and watching and debugging the value being saved is the pathname so no error and all appears to work, just the database has no path, just this string "System.Web.HttpPostedFileWrapper". Any comments greatly appreciated</p> <p>Here is my controller code :</p> <pre><code>[AcceptVerbs(HttpVerbs.Post)] public ActionResult SiteLocationEdit(int id, FormCollection collection) { SiteLocation siteLocation = this._siteRepository.GetSite(Convert.ToInt16(collection["SiteId"])).SiteLocation; if (Request.Files.Count &gt; 0 &amp;&amp; Request.Files["SitePlan"].ContentLength &gt; 0) { DeleteFile(siteLocation.SitePlan); siteLocation.SitePlan = SaveFile(Request.Files["SitePlan"], @"~/UploadedFiles", "SitePlan" + siteLocation.SiteId.ToString()); } if (Request.Files.Count &gt; 0 &amp;&amp; Request.Files["SiteImage"].ContentLength &gt; 0) { DeleteFile(siteLocation.SiteImage); siteLocation.SiteImage = SaveFile(Request.Files["SiteImage"], @"~/UploadedFiles", "SiteImage" + siteLocation.SiteId.ToString()); } TryUpdateModel(siteLocation); if (!ModelState.IsValid) return View(siteLocation); this._siteRepository.Save(User.Identity.Name); return RedirectToAction("SiteLocationDetails", new { id = siteLocation.SiteId }); } </code></pre> <p>Here is my View containing a Partial View (shown later in this post)</p> <pre><code>&lt;%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage&lt;Lms.Model.SiteLocation&gt;" %&gt; &lt;asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"&gt; &lt;%= Html.Encode(Model.Site.SiteDescription) %&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"&gt; &lt;%=Html.Script("~/Scripts/jquery.textarea-expander.js")%&gt; &lt;%= Html.ValidationSummary("Location Create was unsuccessful.
