Upload files to Microsoft Sharepoint Server with Ajax and the ASP .NET FileUpload control

The FileUpload control does not work with AJAX, because it needs a full postback to upload a file. So we have to change the AJAX partial postback to a full postback:

ASPX, add a ScriptManager, UpdatePanel, FileUpload and LinkButton control:

<%@ Page Language="C#" AutoEventWireup="true" Codebehind="Default.aspx.cs" Inherits="WebApplicationCSharp._Default" %>

<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
  Namespace="System.Web.UI" TagPrefix="asp" %>
@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
html xmlns="http://www.w3.org/1999/xhtml">
head runat="server">
  <title>Web app c#</title>
  <link rel="stylesheet" type="text/css" href="~/CustomStyles.css">
  <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManagerTest" runat="server">
    <asp:UpdatePanel ID="UpdatePanelTest" runat="server">
        <asp:FileUpload ID="FileUploadTest" runat="server" />
        <asp:LinkButton ID="LinkButtonTest" runat="server" OnClick="LinkButtonTest_Click">Test Upload</asp:LinkButton>

Change Page_Load event

protected void Page_Load(object sender, EventArgs e)
  // Disable AJAX for the 
LinkButtonTest ONLY. Because we are using the FileUpload control, which does not work with AJAX, we need a full PostBack.
  LinkButtonTest.Attributes.Add("OnClick", String.Format("form1.__EVENTTARGET.value = ‘{0}’; form1.submit(); return false;", LinkButtonTest.UniqueID));

Add Click event on LinkButtonTest

The LinkButtonTest is on an AJAX update panel, but by overriding the OnClick event in the Page_Load event,
/// this event will fire with a full postback.
/// </summary>
<param name="sender"></param>
<param name="e"></param>
protected void LinkButtonTest_Click(object sender, EventArgs e)

Add an UploadFile function

public void UploadFile()
  using (SPSite sitecollection = new SPSite("http://localhost"))
    using (SPWeb web = sitecollection.RootWeb)
      if (FileUploadTest.HasFile)
        using (Stream fileContent = FileUploadTest.FileContent)
          string fileName = FileUploadTest.FileName;
          string newListItemImageName = ""; 
          // Get list by name
          SPList list = web.Lists[listName];
          // Get rootfolder of the list
          SPFolder folder = list.RootFolder;
          // Delete the current file if it exists. I can’t find a way to check the existence of a file without an exception and not looping through all the items in the list.
          bool fileExists = false;
          SPFile currentFile = null;
            currentFile = folder.Files[fileName];
            fileExists = true;
          catch { fileExists = false; }
          if (fileExists) { currentFile.Delete(); }
          // Add file to the list
          currentFile = folder.Files.Add(String.Format("{0}/{1}", folder.ServerRelativeUrl, fileName), fileContent);

Using CustomAction to modify system pages in Microsoft Sharepoint Server

Chris O’Brien’s wrote a great article about, customizing the _layouts/settings.aspx page with CustomActions


For example

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
   Title="$Resources:Resources, CustomActionGroupTitle"
   Sequence="9" />

    <UrlAction Url="/CustomSettings.aspx"/>

Store Feature, Job or any other administration configuration information in Microsoft Sharepoint Server

There are many way to store configuration information in WSS, but you can use the hierachical object store (SPPersistedObject Class).
This class provides the methods for an object to automatically serialize its state, persist that state in a permanent store, retrieve it at a later time, and deserialize it back into an in-memory object.
It is explained on http://msdn2.microsoft.com/en-us/library/microsoft.sharepoint.administration.sppersistedobject.aspx and here http://www.bluedoglimited.com/SharePointThoughts/ViewPost.aspx?ID=271
