Files Uploading in Sharepoint Document Library with RadAsyncUpload

[Христо]

Here is how you can upload files in Sharepoint Document Library:

1. Create a new Visual Web Part
2. Add reference to Telerik.Web.UI assembly
3. Register Telerik.Web.UI assembly:

   <%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
   <%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
   <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
   <%@ Register Tagprefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
   <%@ Register Tagprefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>
   <%@ Import Namespace="Microsoft.SharePoint" %>
   <%@ Register Tagprefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
   <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="VisualWebPart1.ascx.cs" Inherits="VisualWebPartProject1.VisualWebPart1.VisualWebPart1" %>
   <%@ Register Assembly="Telerik.Web.UI, Version=2014.2.618.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
   
   <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" ></telerik:RadAsyncUpload>
   <telerik:RadButton runat="server" Text="Submit" ID="RadButton1" OnClick="RadButton1_Click"></telerik:RadButton>

4. Save the file

protected void RadButton1_Click(object sender, EventArgs e)
        {
            foreach (UploadedFile file in RadAsyncUpload1.UploadedFiles)
            {
                String sharePointSite = "http://ajax-sp2010/";
                String documentLibraryName = "Shared Documents";

                using (SPSite oSite = new SPSite(sharePointSite))
                {
                    using (SPWeb oWeb = oSite.OpenWeb())
                    {
                        SPFolder myLibrary = oWeb.Folders[documentLibraryName];

                        Boolean replaceExistingFiles = true;
                        // Upload document
                        SPFile spfile = myLibrary.Files.Add(file.FileName, file.InputStream, replaceExistingFiles);

                        // Commit
                        myLibrary.Update();
                    }
                }
            }
        }

Note that when file is selected it is uploaded in the App_Data folder:
C:\inetpub\wwwroot\wss\VirtualDirectories\80\App_Data\RadUploadTemp
