Check current user exist people or group column

How to check current logged in user name already exist in people or group column of share-point custom list 2013 using c#?
Note: People or group column contains multiple items.
Thanks in advance

You can use javascript to get current user and then perform vlookup on the field
Current use
function CallClientOM()
var context = new SP.ClientContext.get_current();
this.website = context.get_web();
this.currentUser = website.get_currentUser();
context.load(currentUser);
context.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded(sender, args)
alert(currentUser.get_loginName());
function onQueryFailed(sender, args)
alert('request failed ' + args.get_message() + '\n'+ args.get_stackTrace());

People and group column become empty on EDIT ITEM

Hi,
I have 3 people and group columns(Peopleonly type) in my custom content type and list definition from the content type. When I EDIT an item from the list , the values in the 3 people and group column dissappear(meaning the fields are shown empty). Has
anybody come across this behaviour. Any solution/workaround ?

Hi Vipul,
Did this only happen to the EditForm.aspx page of that custom list ?
Is this EditForm.aspx page customized ?
Please also check whether there are some related errors in 14\LOGS.
Please re-create another new EditForm.aspx page using the SharePoint Designer 2010, then check result again.
Thanks

Single line of text/email id to People or Group column

I have a list of employee details, along with their SharePoint email ID. I want to import this list along with a new People or Group column, where it reads the email id and picks the correct user from Active Directory. How to import this?

Hi Abul,
Based on your description, I did a test. When I used users' email address in excel table and imported it to SharePoint list, the column would be saved as Hyperlink or Picture type. If I used Domain\User, after importing it to SharePoint list, the column
would be saved as Single line of text type.
It seems that it only is converted into Single line of text or Hyperlink type when you import a table into SharePoint list, by default. There is not a way to convert the table column in excel file into People column in SharePoint list.
Thanks,

Can't find "people or group"-column in database

Hi,
Where can I find the people and group column in the database in SharePoint
2010? I need this for a report...
I have a list with multiple columns. In the Table "AllUserData" I can find all information of the columns exept the people picker column.
I found this solution:
http://social.technet.microsoft.com/Forums/sharepoint/en-US/1e786892-1386-4e67-8a12-77f9ba0c1f64/where-can-i-find-the-people-or-group-columns-in-alluserdata-table-?forum=sharepointdevelopmentlegacy
But there they are talking about "tp_LeafName" and "tp_DirName" and I can't find these columns...
Any idea?

Found it, needed this tables:
[AllDocs]
[AllUserData]
[AllUserDataJunctions]
[UserInfo]

Unable to select SOME external users in person or group column in SharePoint O365

Here's a head scratcher.
We have an O365 SharePoint(G3) instance.
Sent external users invites to join the site from the SharePoint Group that the external user will be placed.
External users accepted invitations and now have access to the site with the correct permissions.
Permissions assigned to SharePoint Group.
Some external users can be selected for "Assigned to" field (person or group column type).
Some external users canNOT be selected for "Assigned to" field (person or group column type).
When typing external users name that canNOT be selected, the error message "No results found" appears.
Went to Site Settings > Site Permisisons > Check Permissions and typed in external users name that canNOT be selected, the error message "No results found" appears.
I have no idea why this would happen for some external users and not others.
External users that can be selected and those that canNOT be selected are in the same SharePoint Group and have the same permissions.
Could this be due to how the external user set up their account?
Help me please. This is driving my crazy.
Thanks in advance.

Restrict group to edit users in people picke in infopath

hi
I have a document with people picker I want to restrict group A to pick or edit the users in existing document and groupB able to edit the users in people picker how is it possible to make it in InfoPath.

Hello,
This would be easy to do with groups that can access specific sections of the form and then use SharePoint or AD groups to govern access, but unfortunately it does not work in InfoPath.
One alternative possibility is to set up a list in SharePoint and enter the names of the smaller group of people into that list (Person field).
The InfoPath form has a data connection to that list. The form has one section with a people picker and another section with a calculated field that shows the value of the people picker.
When opening the InfoPath form, check if the current user exists in the list and hide the section they should not see.
cheers, teylyn

Caml query to check current logged in user - SharePoint designer

Hi,
I need to create a caml query in SharePoint designer to satisfy the below conditions.
If the logged in user (current user) is a member of a specific group. e.g. Group Name = ISS Owners, ID=5
(OR)
If the logged in user (current user) exists in assigned to field. e.g. Field Name = Assigned To
Reference to the below link is not working for my solutions.
Membership Element (Query)
CAML Query – Membership attribute
Kindly help in resolving caml query issue.
Anandhan.S Remember to 'mark or propose as answer' or 'vote as helpful' as appropriate.

The second condition is pretty straightforward
<Eq>
<FieldRef Name="AssignedTo"/>
<Value Type="Integer">
<UserID />
</Value>
</Eq>
but I don't think you can do the former. The <Membership> condition can only be applied to a <FieldRef>, not a generic <Value> argument.
But what would be the purpose of the first condition in the first place? It's invariant, not related to specific list items. Or is the requirement to return all items if the user is a member of a group (Administrators?), but only assigned-To items if not:
If so, is there some way you can refactor the check for the former condition into some higher level logic?

Send an Email to those who are marked in people/group column

In the discussion boards, I would like to add a people or group column.
So whenever some name is mentioned in that column, I would like an Email to be triggered to that particular person or group.
If this is been created through Task list, I know it would be possible. But I want to achieve the logic of discussion board and want to trigger an Email to someone who might be interested in that particular discussion.
Is there a way to do it ?
Came across this forum which exactly talks about my requirement.

But is there any easier and alternate way to do this? Thanks in advance.

How to add users from person or group field in a sharepoint list to sharepoint group

Hi,
How to add users(single or multiple) from person or group field in a sharepoint list to sharepoint group programmatically?
Any suggestions would be appreciated.
Thank you,
AA.

Hello,
Use SPGroup.AddUser() method to add user in group. I have just written sample code in notepad so it is not tested:
SPSecurity.RunWithElevatedPrivileges(delegate()
using(SPSite Site = new SPSite(SPContext.Current.Site.Url))
Using(SPWeb Web = Site.OpenWeb())
SPList list = web.Lists["ListName"];
SPQuery query=new SPQuery ();
query.Query = "<Where><Eq><FieldRef Name='Title' /><Value Type='Text'>Test</Value></Eq></Where>";
SPListItemCollection items = list.GetItems(query);
if(items.Count > 0)
foreach(SPListItem item in items)
//Get USers from person or group column
SPFieldUser userField = (SPFieldUser)item.Fields.GetField("Users");
SPFieldUserValueCollection userFieldValueCollection = (SPFieldUserValueCollection)userField.GetFieldValue(item["Users"].ToString());
SPGroup spGroup = spSite.RootWeb.Groups[groupName];//group name
if (users.Count != 0)
bool isUserInGroup = false;
foreach (SPFieldUserValue user in users)
foreach (SPUser item in spGroup.Users)
string itemUserName = item.LoginName;
string UserName = user.User.LoginName;
if (itemUserName == UserName)
isUserInGroup = true;
break;
if (!isUserInGroup)
spGroup.AddUser(user.User);
The above code will query list item and then get users from "Users" column. Now it will check whetehr user is already in group not, if not then add user in group.

Filter base on Person or Group column does not work correctly in sharepoint 2013

I have a list that contain "Person or Group"column that set "Allow Multiple Selections" to yes.
In sharepoint 2010 I create view and filter it base on this person or group column equal to [Me]. And it's work correctly.
Now in sharepoint 2013 when I filter view, base on this person or group column equal to [Me], it does not show me any items, although list has data that person or group column set to me.
What's wrong?
Thanks.

If you want to filter the list view when current user is in the group, then I recommend to use theMembership comparator in the
query and add it to the view page in SharePoint Designer:
<Where><Or><Membership Type="CurrentUserGroups"><FieldRef Name="AssignedTo"/></Membership><Eq><FieldRef Name="AssignedTo"/><Value Type="Integer"><UserID Type="Integer"/></Value></Eq></Or></Where>

-Can anybody help me step by step. I just started using powershell today. I am trying to use powershell to check if users exist in AD. I manage to create a script to check for one user at a time but, I really what a script to check multiple users at
the same time. This script is currently telling me everybody does not exist. Even if I put a user that does.

Thanks for the quick help & advice.
here are some example of names in the text file.
Flewellen,  Joel A

Grestner, Allen
- I want to make sure the names in the text file do not exist in AD(Display name). Can I use your script for this? Again, I am a total noob.Currently reading about powershell.
example does notwork:
Import-Module ActiveDirectory
Import-CSV "L:.\Users.txt" -header ("DisplayName") |
Foreach {
        if (Get-ADUser -Identity $_.DisplayName -ErrorAction SilentlyContinue) {Write-host "Domain\
$($_.DisplayName) found in AD"}
        else {Write-host "Domain\$($_.DisplayName) does not exist in AD"}
I think i have to change the Get-ADUser -Identity $_.UserName

Checks users Exists in user group or not?

Hi All,
bool userExsists = SPContext.Current.Web.CurrentUser.Groups.Cast<SPGroup>().Any(g => g.Name.ToLower() == "groupname".ToLower());
Is there ay alternative for findings that user is in group or not? Is it best way to achieve this?

Hi,
To check if a user exists in user group, please use the code below:
string userName = "contoso\\admin";//your user account
string groupName = "SP Members";// your user group
using (SPSite spSite = new SPSite("http://sp")) // your site collection URL
using (SPWeb spWeb = spSite.OpenWeb())
SPUser user = spWeb.EnsureUser(userName);
if (user.Groups.Cast<SPGroup>().Any(g => g.Name.Equals(groupName)))
Console.WriteLine("User " + userName + " is a member of group " + groupName);
else
Console.WriteLine("User " + userName + " is NOT a member of group " + groupName);
Or you can use PowerShell command below:
$w = get-spweb http://my
$gs = $w.SiteGroups
$g = $gs[12]
$user = $g.Users.GetByEmail("[email protected]")
if($user -eq $null){write-host "User Not Found"}
Best regards.
Thanks
