I have a column that has names of the user. The column type is Single line of Text and the user name is stored in the format LastName, FirstName;
I would like to get the user id and email address of the stored user name.
I tried
string fieldValue = item["ProjectManager"] as string;
SPFieldUserValueCollection users = new SPFieldUserValueCollection(item.Web, fieldValue);
if (users != null)
{
/* The users.count is always zero */
foreach (SPFieldUserValue user in users)
{
if (user.User != null)
{
}
}
}
I cannot change the column type to Person or Group and it would remain as Single Line of Text. Please let me know how can I achieve this . I have been trying this for couple of hours now.
Try this:
public SPUser GetUser(SPWeb web, string userstring)
{
var user = FetchUser(web, userstring);
if (user == null)
{
SPPrincipalInfo info = SPUtility.ResolvePrincipal(web, userstring, SPPrincipalType.User, SPPrincipalSource.All, null, false);
if (info!=null)
user = FetchUser(web, info.LoginName);
}
return user;
}
public SPUser FetchUser(SPWeb web, string userstring)
{
return web.AllUsers.Cast<SPUser>().FirstOrDefault(
i => i.Name == userstring || i.LoginName == userstring || i.Email == userstring);
}
From SPUser you get get the user ID.
Get SPUser in your case with:
var user = GetUser(item.Web,fieldValue )

I have a simple application. When a user logs in it creates a session variable and redirects them to another controller that pull up some info from the database. I need to store this to a session variable then return it to the view. The initial part is fine, it returns it and I see the information. However, when I try to create a search query it returns that the session is null even though I never clear it.
public ActionResult ShowCourses()
{
if (Session["Username"] != null)
{
string Username = Session["Username"].ToString();
using (DefaultConnection db = new DefaultConnection())
{
var model = from c in db.Courses
where c.Username == Username
select c;
Session["Courses"] = model.ToList();
var Courses = Session["Courses"];
return View(Courses);
}
}
else
{
return RedirectToAction("Login", "Users");
}
}
But when I try to run a search query to loop through the session, it brings back that Courses is null. The problem is that coursesQuery returns null and I'm not sure why.
public ActionResult SearchCourses(string query)
{
if (Session["Username"] != null)
{
var coursesQuery = Session["Courses"] as IEnumerable<Course>;
if (coursesQuery != null)
{
// Do Something
}
}
}
You did a .ToList() on the course colleciton before setting to Session.
Try this. Use List<Course> when you read it back.
if (Session["Courses"] != null)
{
var coursesQuery = (List<Course>) Session["Courses"];
}
I am trying to remove the user accounts which are inactive from last 30 days.
I tried fetching User Information List. Checked all of it's properties and fields but coudn't find anything related to last login time.
You can do something like this
public DateTime Get(string attr, string UserName)
{
DomainConfiguration domainConfig = new DomainConfiguration();
using (new SPMonitoredScope("AD Properties"))
{
using (DirectoryEntry domain = new DirectoryEntry("LDAP://" + domainConfig.DomainName, domainConfig.UserName, domainConfig.Password))
{
//DirectorySearcher searcher = new DirectorySearcher(domain, "(|(objectClass=organizationalUnit)(objectClass=container)(objectClass=builtinDomain)(objectClass=domainDNS))");
DirectorySearcher searcher = new DirectorySearcher(domain);
searcher.PageSize = 1000;
searcher.Filter = "(SAMAccountName='" + UserName + "')";
//searcher.Filter = "(|(objectCategory=group)(objectCategory=person))";
searcher.Filter = "(&(objectClass=user) (cn=" + UserName + "))";
var user = searcher.FindOne();
DateTime LastLogon = DateTime.FromFileTime((Int64)user.Properties["lastLogon"].Value);
return LastLogon;
}
}
}
Hope this Helps you.
I do not know why it does gives me the some older dates than i expected.
but at least it will compile and run.
using System.DirectoryServices.AccountManagement;
private static DateTime? GetUserIdFromDisplayName(string displayName)
{
// set up domain context
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
{
// find user by display name
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, displayName);
if (user != null)
{
return user.LastLogon;
}
else
{
return null;
}
}
}
In my current project I need write in a table all values are changed in the application.
Ex. the guy update the UserName, I need put in a table UserName old value "1" new value "2".
I tried use the ObjectStateEntry but this return all fields. I think the FW return all because my code.
public USER Save(USER obj)
{
using(TPPTEntities db = new TPPTEntities())
{
db.Connection.Open();
USER o = (from n in db.USERs where n.ID == obj.ID select n).FirstOrDefault();
if (o == null)
{
o = new USER()
{
BruteForce = 0,
Email = obj.Email,
IsBlock = false,
LastLogin = DateTime.Now,
Name = obj.Name,
UserName = obj.UserName,
UserPassword = new byte[0],
};
db.AddToUSERs(o);
}
else
{
o.Email = obj.Email;
o.Name = obj.Name;
o.UserName = obj.UserName;
}
db.SaveChanges();
db.Connection.Close();
}
return obj;
}
A way to get old and new values is this:
var ose = this.ObjectStateManager.GetObjectStateEntry(o.EntityKey);
foreach (string propName in ose.GetModifiedProperties())
{
string.Format("Property '{0}', old value: {1}, new value: {2}",
propName, ose.OriginalValues[propName], ose.CurrentValues[propName]);
}
This is pretty useless, of course, but I'm sure you'll know what to do in the foreach loop to store the changes.
Is this a WCF Service? In that case, the changes will probably never come trough since changes to the Object Graph are made where the Object Context is not available. Consider using Self-Tracking Entities
I'm struggling with the SharePoint 2007 AfterProperties. I've a people input field, where several people can be added.
On the ItemUpdating event I now need to determine which users were added, removed or stayed the same.
Unfortunately this becomes quit difficult, as the id of the untouched users turns to -1 in the AfterProperties, so that I cant not use SPFieldUserValueCollection to find the user.
An example. properties.ListItem["AssignedTo"].ToString() shows:
1;#domain\user1;#2;#domain\user2
properties.AfterProperties["AssignedTo"].ToString() shows:
-1;#domain\user1;#-1;#domain\user2;#3;#domain\user3 <-Added a user
I planned to use following code, to determine removed and added users:
foreach (SPFieldUserValue oldUser in oldUserCollection)
{
if (newUserCollection.Find(x => x.LookupId == oldUser.LookupId) == null)
{
RemoveRole(aListItem, oldUser.User, roleDefCollection[workerRoleName]);
}
}
foreach (SPFieldUserValue newUser in newUserCollection)
{
if(oldUserCollection.Find(x => x.User.LoginName == newUser.LookupValue) == null)
{
AddRole(aListItem, newUser.User, roleDefCollection[workerRoleName]);
}
}
How can I archive, that the AfterProperties show the right lookupid?
Solved the problem by myself. Instead of using the SPFieldUserCollection I'm now using a list and try to parse all the information by myself out of the string.
Regex reg = new Regex(#"\;\#");
string[] usernameParts = reg.Split(usernames);
List<SPUser> list = new List<SPUser>();
int id;
foreach (string s in usernameParts)
{
if (!string.IsNullOrEmpty(s))
{
if (!Int32.TryParse(s, out id))
{
if (list.Find(x => x.ID == spweb.Users[s].ID) == null)
list.Add(spweb.Users[s]);
}
else
{
if (Convert.ToInt32(s) != -1)
{
if (list.Find(x => x.ID == Convert.ToInt32(s)) == null)
list.Add(spweb.Users.GetByID(Convert.ToInt32(s)));
}
}
}
}
I am using managed client side object model in sharepoint 2010. And I want to get loginaName of the AssignedTo user in Task list.
In server side object model I use SPFieldUserValue.User.LoginName to get this property but in client side object model FieldUserValue.User does not exists.
How can I resolve this situation ?
Thanks
Here is the code for that. I've taken an example of AssignedTo field from Task list. I hope that helps.
public static User GetUserFromAssignedToField(string siteUrl)
{
// create site context
ClientContext ctx = new ClientContext(siteUrl);
// create web object
Web web = ctx.Web;
ctx.Load(web);
// get Tasks list
List list = ctx.Web.Lists.GetByTitle("Tasks");
ctx.Load(list);
// get list item using Id e.g. updating first item in the list
ListItem targetListItem = list.GetItemById(1);
// Load only the assigned to field from the list item
ctx.Load(targetListItem,
item => item["AssignedTo"]);
ctx.ExecuteQuery();
// create and cast the FieldUserValue from the value
FieldUserValue fuv = (FieldUserValue)targetListItem["AssignedTo"];
Console.WriteLine("Request succeeded. \n\n");
Console.WriteLine("Retrieved user Id is: {0}", fuv.LookupId);
Console.WriteLine("Retrieved login name is: {0}", fuv.LookupValue);
User user = ctx.Web.EnsureUser(fuv.LookupValue);
ctx.Load(user);
ctx.ExecuteQuery();
// display the user's email address.
Consol.writeLine("User Email: " + user.Email);
return user;
}
The fuv.LookupValue may contain the display name, not the login name, so my suggestion is (assuming you have the FieldUserValue - fuv in code (as descibed by #ekhanna):
var userId = fuv.LookupId;
var user = ctx.Web.GetUserById(userId);
ctx.Load(user);
ctx.ExecuteQuery();
You get the column which as the FieldUserValue from the list, once you have that you use the lookup id value and then query against the Sites User Info List. In the example below I cache the results to prevent looking up the same id more than once since the query can be expensive.
private readonly Dictionary<int, string> userNameCache = new Dictionary<int, string>();
public string GetUserName(object user)
{
if (user == null)
{
return string.Empty;
}
var username = string.Empty;
var spUser = user as FieldUserValue;
if (spUser != null)
{
if (!userNameCache.TryGetValue(spUser.LookupId, out username))
{
var userInfoList = context.Web.SiteUserInfoList;
context.Load(userInfoList);
var query = new CamlQuery { ViewXml = "<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='ID' /><Value Type='int'>" + spUser.LookupId + "</Value></Eq></Where></Query></View>" };
var users = userInfoList.GetItems(query);
context.Load(users, items => items.Include(
item => item.Id,
item => item["Name"]));
if (context.TryExecuteQuery())
{
var principal = users.GetById(spUser.LookupId);
context.Load(principal);
context.ExecuteQuery()
username = principal["Name"] as string;
userNameCache.Add(spUser.LookupId, username);
}
}
}
return username;
}
Everything above worked for me, but instead of:
FieldUserValue fuv = (FieldUserValue)targetListItem["AssignedTo"];
I used:
FieldUserValue[] fuv = targetListItem["AssignedTo"] as FieldUserValue[];
