I am trying to add some data to SharePoint list in SharePoint Foundation 2013. All pages of site collection will try to write to the same list.
When pages are accessed currently, data added to list are corrupted.
Here is my code
<script type="text/c#" runat="server">
public string username = SPContext.Current.Web.CurrentUser.Name;
static readonly object _object = new object();
public string CurrentTime;
protected void Page_Load(object sender, EventArgs e)
{
SPSite MySite = SPContext.Current.Site;
SPWeb MyWeb = MySite.OpenWeb();
MyWeb.AllowUnsafeUpdates = true;
// Fetch the List
SPList ClientList = MyWeb.Lists["NameOfThePage"];
lock (_object) {
SPListItem itemToAdd = ClientList.Items.Add();
itemToAdd["UserName"] = username;
itemToAdd["DateVisited"] = prevTime;
itemToAdd["TimeSpent"] = duration;
itemToAdd["PageName"] = prevPage.Replace(".aspx", " ");
itemToAdd["Title"] = Page.Title;
itemToAdd.Update();
}
}
}
//ignore
}
I have tried using lock() but it is not giving desired result. I think because _object is new instance for each case. Please suggest me how to overcome this.

Scenario : I need Refresh/Filter the Items/records displayed in List View Web Part on the same page based on selected filters. So I created Visual Web Part and tried to modify the View of List View Web Part Programmatically. So far i have reached till here :
string spListName = "Job";
protected void BtnSearchClick(object sender, EventArgs e)
{
try
{
SPWeb oWebsite = SPContext.Current.Web;
SPList oList = oWebsite.Lists[spListName];
XsltListViewWebPart xsltWP = null;
SPWebPartManager wpManager = WebPartManager.GetCurrentWebPartManager(Page) as SPWebPartManager;
//Code to Find List View Web Part on Page
foreach (System.Web.UI.WebControls.WebParts.WebPart wp in wpManager.WebParts)
{
if (wp.GetType().Name == "XsltListViewWebPart")
xsltWP = wp as XsltListViewWebPart;
}
oWebsite.AllowUnsafeUpdates = true;
StringBuilder strbPreQuery = new StringBuilder("<Where><Eq>");
StringBuilder strbPostQuery = new StringBuilder("</Value></Eq></Where>");
string strQueryKeyword = "<FieldRef Name='Customer' /><Value Type='Lookup'>";
SPQuery oQuery = new SPQuery();
oQuery.Query = strbPreQuery.ToString() + strQueryKeyword + txtCustomer.Text + strbPostQuery.ToString();
SPListItemCollection itemCol = oWebsite.Lists[spListName].GetItems(oQuery);
PropertyInfo pi = xsltWP.GetType().GetProperty("ContextView", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);
SPView view = (SPView)(pi.GetValue(xsltWP, null));
view.Query = oQuery.Query;
view.Update();
wpManager.SaveChanges(xsltWP);
xsltWP.DataBind();
oWebsite.AllowUnsafeUpdates = false;
}
catch (Exception ex)
{
Response.Write(ex);
}
}
The Above code works but now I am facing following problems :
The results updation requires page refresh so If I add following code, results are updated but filter values in visual web part is lost.
this.Context.Response.Redirect(this.Context.Request.Url.ToString());
Filtered applied by one user is also reflected to another user.
Can some please help in to address these two problems I have ? that is I want
To preserve the filter values and results to be modified at the same time
The filtering should be only for one user and not for all.
Any help in this regards will be appreciated.
Create a SPQuery that will hold the default value of the view.
then after passing the value,
Use this to revert back the default query of the view.
SPView _view;
protected void Page_Unload(object sender, EventArgs e)
{
//your code
SPView view = (SPView)(pi.GetValue(xsltWP, null));
view.Query = _view.Query;
view.Update();
}
I created an event receiver that should trigger a SharePoint designer workflow, however this never happens. This part of the code never evaluates to true for the guid and workflow association: if (association.BaseId == workflowGuid). I am a bit stumped and not quite sure why it's not working. Any insight would be appreciated...and my code is below. Basically when an item is added to my list, it should trigger my Sharepoint designer workflow but this never happens and I can manually start the workflow fine.
public override void ItemAdded(SPItemEventProperties properties)
{
base.ItemAdded(properties);
startWF(properties);
}
private void startWF(SPItemEventProperties properties)
{
try
{
//bool startWF = false;
string strWorkflowID = "{c66ff94f-ba7c-4495-82fe-e73cdd18bad9}";
//string statusVal = properties.AfterProperties["eRequest Division"].ToString();
SPListItem li = properties.ListItem;
//using (SPWeb web = li.Web)
using (SPWeb web = properties.OpenWeb())
{
using (SPSite site = web.Site)
{
SPWorkflowManager mgr = site.WorkflowManager;
SPList parentList = li.ParentList;
//SPList list = web.Lists["Charitable and Political"];
SPWorkflowAssociationCollection associationCollection = parentList.WorkflowAssociations;
LookUpAndStart(li, mgr, associationCollection, "{c66ff94f-ba7c-4495-82fe-e73cdd18bad9}");
}
}
}
catch (Exception ex)
{
}
}
private static void LookUpAndStart(SPListItem listItem, SPWorkflowManager mgr, SPWorkflowAssociationCollection associationCollection, string workflowID)
{
foreach (SPWorkflowAssociation association in associationCollection)
{
Guid workflowGuid = new Guid(workflowID);
//if (association.Name.ToLower().Equals(workflowGuid))
//if (association.BaseId == workflowGuid)
//if (association.BaseId.ToString("B").Equals(workflowGuid))
if (association.BaseId == workflowGuid)
{
string data = association.AssociationData;
SPWorkflow wf = mgr.StartWorkflow(listItem, association, data, true);
break;
}
}
}
}
}
In my case the following was the problem.
Declarative workflows will not start automatically if the following conditions are true:
The Windows SharePoint Services Web application runs under a user's domain account.
The user logs in by using this domain account.
The site displays the user name as System Account.
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.
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.)
