    <p>We're 4 guys making a website for our final school project. We need to allow a user to upload a pdf. We're using Visual Studio 2012, and we have a Master page set up, and the whole login-process and user-creation works. We're using jQuery, and also jQueryMobile because the site needs to work for phones as well, and this makes it a bit easier.</p> <p>But when we want to check the files the client is trying to upload in our code behind, Request.Files is always empty. Why is this?</p> <p>I have the enctype set in the form I'm using, so I should be fine. It looks like the page reloads when I click the upload-button, and the text-field in the file-input gets cleared. Then after this, it runs the code behind method.</p> <p>The output we get is:</p> <pre><code>HALLOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! In the house Files[] size is 0 </code></pre> <p>The Master page that looks like this:</p> <pre><code> &lt;%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Main.Master.cs" Inherits="SendEtBrev.Main" %&gt; &lt;!DOCTYPE html&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;SendEtBrev.dk&lt;/title&gt; &lt;meta http-equiv="Pragma" content="no-cache" /&gt; &lt;meta http-equiv="Expires" content="-1" /&gt; &lt;meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;" /&gt; &lt;meta name="MobileOptimized" content="width" /&gt; &lt;meta name="HandheldFriendly" content="true" /&gt; &lt;link rel="stylesheet" type="text/css" href="/Styles/reset.css" /&gt; &lt;script src="http://code.jquery.com/jquery-1.9.1.min.js"&gt;&lt;/script&gt; &lt;script src="/Js/fixes.js"&gt;&lt;/script&gt; &lt;script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"&gt;&lt;/script&gt; &lt;link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" /&gt; &lt;link rel="stylesheet" type="text/css" href="/Styles/sendetbrev.css" /&gt; &lt;asp:ContentPlaceHolder ID="head" runat="server" /&gt; &lt;/head&gt; &lt;body&gt; &lt;header&gt; &lt;div class="headerbox"&gt; &lt;div class="headerlogo"&gt; &lt;img class="autosizedimage" src="/Billeder/Logo.png" /&gt; &lt;/div&gt; &lt;asp:LoginView ID="LoginViewMenu" runat="server"&gt; &lt;LoggedInTemplate&gt; &lt;a href="/Account/Minkonto.aspx"&gt;Min konto&lt;/a&gt; &lt;a href="/Account/Logout.aspx"&gt;Log ud&lt;/a&gt; &lt;/LoggedInTemplate&gt; &lt;/asp:LoginView&gt; &lt;br /&gt; &lt;/div&gt; &lt;/header&gt; &lt;br /&gt; &lt;br /&gt; &lt;div&gt; &lt;asp:ContentPlaceHolder ID="centercontent" runat="server" /&gt; &lt;/div&gt; &lt;footer&gt; &lt;/footer&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>My ASPX code is this:</p> <pre><code>&lt;%@ Page Language="C#" MasterPageFile="~/Main.Master" ValidateRequest = "False" AutoEventWireup="true" CodeBehind="Side1Uploadfil.aspx.cs" Inherits="SendEtBrev.SendBrev.Side1Uploadfil" %&gt; &lt;asp:Content ID="Content1" ContentPlaceHolderID="centercontent" runat="server" &gt; &lt;asp:Literal ID="introText" runat="server"/&gt; &lt;br /&gt; &lt;br /&gt; &lt;asp:Literal ID="AccepteredeFormater" runat="server" /&gt; &lt;br /&gt; .pdf&lt;br /&gt; &lt;!-- vises kun hvis der er en fejlbesked ved upload --&gt; &lt;asp:Literal ID="errorMessage" runat="server" EnableViewState="false" /&gt;&lt;br /&gt; Select a file to upload: &lt;form id="form1" name="form1" method="post" runat="server" enctype="multipart/form-data" &gt; &lt;input type="file" accept="*.pdf" id="fileUploadControl" name="fileUploadControl" runat="server" /&gt; &lt;asp:Button runat="server" ID="btnUpload" OnClick="btnUploadClick" Text="Upload" /&gt; &lt;br/&gt;&lt;br/&gt; &lt;br /&gt; &lt;/form&gt; &lt;asp:Button ID="FortsaetKnap" runat="server" data-role="none" CssClass="knap1" Visible="False" OnClientClick="javascript:location.replace('/SendBrev/Side2Modtager.aspx');" /&gt;&lt;br /&gt; &lt;/asp:Content&gt; </code></pre> <p>And my code behind is this:</p> <pre><code>using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Web; using System.Web.Script.Services; using System.Web.UI; using System.Web.UI.HtmlControls; using iTextSharp.text.pdf; using iTextSharp.text.xml; using System.Text.RegularExpressions; using System.Web.UI.WebControls; using System.IO; namespace SendEtBrev.SendBrev { public partial class Side1Uploadfil : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { introText.Text = "Du er nu klar til at sende et brev."; AccepteredeFormater.Text = "Følgende filformater accepteres:"; FortsaetKnap.Text = "Fortsæt"; btnUpload.Text = "Upload"; } protected void btnUploadClick(object sender, EventArgs e) { Response.Write("HALLOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); Console.WriteLine("HALLOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); Debug.WriteLine("HALLOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); if (fileUploadControl != null) { Response.Write("In the house"); Console.WriteLine("In the house"); Debug.WriteLine("In the house"); } if (Page.Request.Files.Count &gt; 0) { { //Get the first file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
