How do I add a folder to current document library (well if the folder does not exists in the current document library)?
(Current being where ever the end user is)
(I am going to add this code to itemAdded event handler)
curSPList.Items.Add("My Folder Name", SPFileSystemObjectType.Folder);
will create a new folder in any SharePoint list, including a document library. If you plan on implementing this in an event handler you can get the reference to the SPList from the "List" property of the SPItemEventProperties parameter.
Here is the final code that works. Creates a Folder "uHippo" in the current document library if "uHippo" does not exists.
public override void ItemAdded(SPItemEventProperties properties)
{
base.ItemAdded(properties);
using (SPSite currentSite = new SPSite(properties.WebUrl))
using (SPWeb currentWeb = currentSite.OpenWeb())
{ SPListItem oItem = properties.ListItem;
string doclibname = "Not a doclib";
//Gets the name of the document library
SPList doclibList = oItem.ParentList;
if (null != doclibList)
{
doclibname = doclibList.Title;
}
bool foundFolder = false; //Assume it isn't there by default
if (doclibList.Folders.Count > 0) //If the folder list is empty, then the folder definitely doesn't exist.
{
foreach (SPListItem fItem in doclibList.Folders)
{
if (fItem.Title.Equals("uHippo"))
{
foundFolder = true; //Folder does exist, break loop.
break;
}
}
}
if (foundFolder == false)
{
SPListItem folder = doclibList.Folders.Add(doclibList.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, "uHippo");
folder.Update();
}
}
}

I want to track if the users have read sharepoint 2010 document center's documents, currently user infos are not stored in audit logs, is there any way to do it?
It gets stored in audit logs.
Enable auditing for that particular document library and then get the details using the following code:
SPSite oSPsite = new SPSite
SPList doclib= oSPWeb.Lists["doclib"];
SPWeb oSPWeb = oSPsite.OpenWeb()
SPListItemCollection doclibitems= doclib.Items;
foreach (SPListItem odoclibItem in doclibitems)
{
odoclibItem .Audit.AuditFlags = SPAuditMaskType.View;
// odoclibItem .Audit.AuditFlags = SPAuditMaskType
SPAuditQuery oquery = new SPAuditQuery(oSPsite);
oquery.RestrictToListItem(odoclibItem );
odoclibItem .Audit.Update();
SPAuditEntryCollection oAuditEntryCollection =SPsite.Audit.GetEntries(oquery);
foreach (SPAuditEntry entry in oAuditEntryCollection)
{
if (entry.Event == SPAuditEventType.View)
{
id = Convert.ToString(entry.UserId);
// get the user name and other details here
}
}
}
I found the solution. Here is the steps.
1- Create a class library.
2- Right click the library and add new item.
3- Select ASP.NET Module under Web node.
4- Add PreRequestHandlerExecute event handler inside Init.Here is my code.
public void Init(HttpApplication context)
{
context.PreRequestHandlerExecute += context_PreRequestHandlerExecute;
}
5- Methods
void context_PreRequestHandlerExecute(object sender, EventArgs e)
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
var app = sender as HttpApplication;
if (app != null)
{
string requesturl = app.Request.Url.ToString();
string file = string.Empty;
// if document opens in browser
if (app.Request.QueryString["Source"] != null && app.Request.QueryString["id"] != null && app.Request.QueryString["Source"].StartsWith(documentSiteUrl))
{
file = app.Request.QueryString["id"].Remove(0, app.Request.QueryString["id"].LastIndexOf('/'));
Worker(file);
}
// if document opened installed office apps or downloaded the document
if (requesturl.StartsWith(SiteUrl))
{
requesturl = requesturl.Remove(0, requesturl.LastIndexOf('/') + 1);
Worker(requesturl);
}
}
});
}
private void Worker(string requesturl)
{
#region ext control
List<string> extList = new List<string>(Exts.Split(';'));
bool result = false;
foreach (string item in extList)
{
if (requesturl.EndsWith(item))
{
result = true;
break;
}
}
#endregion
if ((!requesturl.Contains(".aspx")) && (!requesturl.EndsWith("/")) && result)
{
SPWeb web = SPContext.Current.Web;
String fileName = requesturl.Substring(requesturl.LastIndexOf("/") + 1);
// Add log
web.AllowUnsafeUpdates = true;
AddReadInfo(web.CurrentUser, fileName, web);
web.AllowUnsafeUpdates = false;
}
}
private void AddReadInfo(SPUser sPUser, string fileName, SPWeb web)
{
#region Logging
SPList logList = web.Lists.TryGetList("LogList");
if (logList != null)
{
SPListItem item = logList.Items.Add();
item["User"] = sPUser.Name;
item["Document"] = fileName;
item["Read"] = "Read";
item.Update();
}
#endregion
}
6- Don't forget signing the project.
7- Build Project.
8- Add dll to GAC and BIN folder under the C:\inetpub\wwwroot\wss\VirtualDirectories\80\ folder.
9- Open IIS Manager.
10- Find your site nod and select.
11- Open Modules.
12- Right click under modules page and select Add Managed Module option.
13- Give a name and select your module under dropdownlist.
14- IIS reset.
I have been asked to retrieve the contents of a document library and display them on a webpage with links to download using MVC. I can retrieve all the documents from the library with no issue. However when the documents are stored within subfolders in my document library my links only open the folder.
My document library structure is
Document Library
Document 1
Document 2
Document 3
Folder 1
Document 4
Folder 2
Document 5
I need to be able to get the child documents from within the folders and not just the documents within the document library.
Here is my code:
namespace SharePointMVC.Controllers
{
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
DefaultModel model = new DefaultModel();
List<DocumentModel> documents = new List<DocumentModel>();
List<FolderModel> folders = new List<FolderModel>();
List<object> itemModels = new List<object>();
using (ClientContext context = new ClientContext("MYSPSITE"))
{
List list = context.Web.Lists.GetByTitle("MYDOCUMENTLIBRARY");
context.Load(list);
CamlQuery query = new CamlQuery();
query.ViewXml = "<View/>";
ListItemCollection listitems = list.GetItems(query);
context.Load(list);
context.Load(listitems);
context.ExecuteQuery();
foreach (ListItem listItem in listitems)
{
IEnumerable<object> items = ProcessListItems(listItem);
itemModels.AddRange(items);
}
model.Documents = documents;
}
return View(model);
}
public IEnumerable<object> ProcessListItems(ListItem listItem)
{
List<object> items = new List<object>();
if (listItem.FileSystemObjectType == FileSystemObjectType.Folder)
{
FolderModel FolderModel = new FolderModel();
foreach (ListItem childListItem in listItem.childItems)
{
IEnumerable<object> childItems = ProcessListItems(childListItem);
}
items.Add(FolderModel);
}
else
{
DocumentModel documentModel = new DocumentModel();
items.Add(documentModel);
}
}
public ActionResult About()
{
return View();
}
}
}
Any help will be greatly appreciated!
Try changing query.ViewXml = "<View/>"; to query.ViewXml = "<View Scope=\"Recursive\"/>";
This tell SharePoint to return items from all folders. If you want folder information returned as well, change Recursive to RecursiveAll.
I have this event receiver c# class that I am trying to implement on a Sharepoint site. It did not work. I have deployed it from visual studio 2010 after it was build ok. Does anyone see what is the problem? Is the code ok? or is the problem on the SP? Thank you.
- here is the new code
using System;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Workflow;
namespace EventReceiverCFolder.EventReceiver1
{
/// <summary>
/// List Item Events
/// </summary>
public class EventReceiver1 : SPItemEventReceiver
{
/// <summary>
/// An item is being added.
/// </summary>
public override void ItemAdded(SPItemEventProperties properties)
{
try
{
if (properties.ListTitle == "CF") // list where the item was added
{ // if item was added to this list then create a folder on - Dlib - list
UpdateFolder(properties);
}
}
catch (Exception ex)
{
properties.Status = SPEventReceiverStatus.CancelWithError;
properties.ErrorMessage = ex.Message;
properties.Cancel = true;
}
}
private void UpdateFolder(SPItemEventProperties properties)
{
string foldername = properties.ListItem["Title"].ToString();
try
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
//inside RunWithElevatedPriviliges I need to open a new site (an elevated site)
using (SPSite site = new SPSite(properties.Web.Site.ID))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;
SPList list = web.Lists.TryGetList("DLib"); // this is doc Library where the new folder will be created
//note that we are creating a list item, not a folder - a folder IS a list item
SPListItem createdFolder = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, null);
if (createdFolder != null)
{
createdFolder["Name"] = foldername;
createdFolder.Update();
}
list.Update();
}
}
});
}
finally { }
}
}
}
Don't do this: SPUser privilegedAccount = properties.Web.AllUsers[#"SHAREPOINT\SYSTEM"];
Read up on using SPSecurity.RunWithElevatedPrivileges. See the MSDN documentation here.
Also don't do a using (SPSite... and inside the using block you try to get the web via SPContext.Current - that web won't be elevated anymore.
The correct way is something along these lines (I didn't try this, so it' just to give you an idea where you are headed):
private void UpdateFolder(SPItemEventProperties properties)
{
string foldername = properties.ListItem["Title"].ToString();
SPSecurity.RunWithElevatedPrivileges(delegate()
{
//inside RunWithElevatedPriviliges I need to open a new site (an elevated site)
using (SPSite site = new SPSite(properties.Web.Site.ID))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;
SPList list = web.Lists.TryGetList("ListTitle"); //is that really the list title?
//note that we are creating a list item, not a folder - a folder IS a list item
SSPListItem createdFolder = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, null);
if (newFolder != null)
{
createdFolder["Name"] = foldername;
createdFolder.Update();
}
list.Update();
}
}
});
}
Also try to debug your code, set breakpoints etc.
I had to get folder name like this:
string foldername = Convert.ToString(properties.AfterProperties["Title"]);
Did you try to debug it? try to debug and tell us what error you are getting.
BUT before you debug first use sharepoint manager to see if your event receiver is attached properly.
If you dont know how to debug sharepoint event receiver then please see this
Using the following block of code, the listItem.Update fails with a NullReferenceException:
SPWeb web = null;
SPList list = null;
SPListItem listItem = null;
try
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite(this.SiteUrl))
{
web = site.OpenWeb();
list = web.Lists[this.ListName];
listItem = list.Items.Add();
listItem["Background"] = "foo";
}
}
);
listItem.Update();
}
catch
{
}
finally
{
web.Dispose();
}
If I move the listItem.Update() method inside of the anonymous delegate, I get "Operation is not valid due to the current state of the object."
Yes, I've combed through SO and have tried many permutations without success.
Any ideas?
Update:
After the first comment, I tried to remove the anonymous delegate from the code to see if it fared any better:
// store the selected item to pass between methods
public T SelectedItem { get; set; }
// set the selected item and call the delegate method
public virtual void Save(T item)
{
SelectedItem = item;
try
{
SPSecurity.RunWithElevatedPrivileges(SaveSelectedItem);
}
catch
{
}
}
public virtual void SaveSelectedItem()
{
if (SelectedItem != null)
{
using (SPSite site = new SPSite(this.SiteUrl))
{
using(SPWeb web = site.OpenWeb())
{
SPList list = web.Lists[this.ListName];
SPListItem listItem = list.Items.Add();
//UpdateListItem(listItem, SelectedItem);
listItem["Background"] = "foo";
listItem.Update();
}
}
}
}
And this still fails "Operation is not valid due to the current state of the object." In both code samples, it looks like site.Impersonating is false. I am using Windows Auth, and Impersonation in the web.config. This is running from the ASP.Net Development server.
I found an example from this site (blackninjasoftware). I create a reference to the site, grab its SystemAccount token and then create another reference to the site, using the admin token. It seemed a little hackish to me at first - but hey - I have a deadline.
Final working method body now looks like:
SPListItem new_item = null;
SPSite initialSite = new SPSite(this.SiteUrl);
using (var site = new SPSite(this.SiteUrl, initialSite.SystemAccount.UserToken))
{
// This code runs under the security context of the SHAREPOINT\system
// for all objects accessed through the "site" reference. Note that it's a
// different reference than SPContext.Current.Site.
using (var elevatedWeb = site.OpenWeb())
{
elevatedWeb.AllowUnsafeUpdates = true;
SPList list = elevatedWeb.Lists[this.ListName];
new_item = list.Items.Add();
UpdateListItem(new_item, item);
if (new_item != null)
{
new_item.Update();
}
}
}
initialSite.Dispose();
Can anyone see why this should not work:
SPSite topNavigationSite = new SPSite("http://moss");
SPWeb topNavigationWeb = topNavigationSite.OpenWeb();
SPNavigationNodeCollection topNavigationBarNodes = topNavigationWeb.Navigation.TopNavigationBar;
SPNavigationNode updateNode = topNavigationBarNodes.Navigation.GetNodeByUrl("/about");
updateNode.Url = "";
topNavigationWeb.Update();
I can see debugging that the url get's set to "" but when the page renders, the navigation still shows the url as /about/default.aspx
I'm running this in page_load and expected it to update the moss database with the new url value.
I know this is 3years old! but as there is no where online about updating a current url!
I had to do some debugging and this is what iv come up with! By the way I got the hint from
topNavigationWeb.Update();
indicating that its updating a list! hint hint!
a bit of background! I wanted to update the quick links from a list when they add, update and delete an item from the list! On my list I have two columns Title and URL!
I then created a project in VS 2010, its an event receiver that is connected only to that list (done in the elements.xml file)
within the .cs file I added item added, item deleting(not deleted ;) ) and item updated
public override void ItemAdded(SPItemEventProperties properties)
public override void ItemUpdated(SPItemEventProperties properties)
public override void ItemDeleting(SPItemEventProperties properties)
now within each method you can simply call this method!
add/update
public static void AddQuickLaunchItem(string header, string url, SPWeb web)
{
SPNavigationNodeCollection quickLaunch = web.Navigation.QuickLaunch;
// try to get quick launch header
SPNavigationNode nodeHeader =
quickLaunch.Cast<SPNavigationNode>().Where(n => n.Title == header).FirstOrDefault();
//if header not found create it
if (nodeHeader == null)
{
nodeHeader = quickLaunch.AddAsFirst(new SPNavigationNode(header, url,true));
}
else
{
web.AllowUnsafeUpdates = true;
nodeHeader = quickLaunch.Cast<SPNavigationNode>().Where(n => n.Title == header).First() ;
nodeHeader.Url = url;
web.AllowUnsafeUpdates = false;
}
nodeHeader.Update();
web.Update();
}
the first part is checking if the node exists using the title (header)! I'm comparing between what headers there are and from the list item:
SPNavigationNode nodeHeader =
quickLaunch.Cast<SPNavigationNode>().Where(n => n.Title == header).FirstOrDefault();
this part is the comparison:
n.Title == header
I'm getting these values (header and url / spweb) like so:
public static void AddQuickLaunchItem(string header, string url, SPWeb web)
the method that is calling the above would look like this:
private void addloopweblinks(SPSite siteCollection, SPItemEventProperties properties)
{
// Enumerate through each site and apply branding.
foreach (SPWeb web in siteCollection.AllWebs)
{
AddQuickLaunchItem(properties.ListItem["Title"].ToString(), properties.ListItem["URL"].ToString(), web);
}
}
and the above method is called within the itemadded and itemupdated ;) passing the values like so:
public override void ItemAdded(SPItemEventProperties properties)
{
using (SPSite siteCollection = new SPSite(properties.WebUrl))
{
if (siteCollection != null)
{
addloopweblinks(siteCollection, properties);
}
}
}
similar things can be done for the delete ;)
SPNavigationNode nodeHeader =
quickLaunch.Cast().Where(n => n.Title == header).FirstOrDefault();
that will get the node!
nodeHeader.delete();
nodeHeader.update();
that will delete the item!
so in your case what you need, I don't know if you noticed it was this part:
web.AllowUnsafeUpdates = true;
nodeHeader = quickLaunch.Cast<SPNavigationNode>().Where(n => n.Title == header).First() ;
nodeHeader.Url = url;
web.AllowUnsafeUpdates = false;
nodeHeader.Update();
web.Update();
as you can see what i mean by the hint! nodeHeader.Update(); didnt update the url, when debugging it does change but when i go to the update part it doesnt work :( and it clicked in i need web.AllowUnsafeUpdates = true; loool only becuse I experienced a similar situation before!
for you it would be:
using(SPSite topNavigationSite = new SPSite("http://moss"))
{
using(SPWeb topNavigationWeb = topNavigationSite.OpenWeb())
{
web.AllowUnsafeUpdates = true;
SPNavigationNodeCollection topNavigationBarNodes =topNavigationWeb.Navigation.TopNavigationBar;
SPNavigationNode updateNode = topNavigationBarNodes.Navigation.GetNodeByUrl("/about");
updateNode.Url = "";
updateNode.Update();
web.Update();
web.AllowUnsafeUpdates = false;
}
}
If the user doesnt have the sufficent rights than you need to encapsulate the above with runwithelevatedprivalages :) hope this helps :)
Have you tried:
updateNode.Update();
topNavigationWeb.Update();
It doesn't look like you are updating the SPNavigationNode object. (Note: you may not need the second Update call.)
