Hello,
This is sample code to get item level permisison: (Just written in notepad so it is not tested)
public void ItemLevelPermission()
SecurableObject curObj = null;
ListItem curItem = ctx.Web.Lists.GetByTitle("LibraryName").GetItemById(ItemId); -> Use Id of file or folder.
IEnumerable roles = null;
roles = ctx.LoadQuery(
curObj.RoleAssignments.Include(
roleAsg => roleAsg.Member,
roleAsg => roleAsg.RoleDefinitionBindings.Include(
roleDef => roleDef.Name, // for each role definition, include roleDef’s Name

How to change 'Modified By' column value when a new file is uploaded in SharePoint 2013 using Client Object Model?

I want to change 'Modified By' column value of a file that is being uploaded using Client Object Model in SharePoint 2013. The problem is that the version of the file is changing. Kindly help me. The code that I am using is:
using (System.IO.Stream fileStream = System.IO.File.OpenRead(m_strFilePath))
Microsoft.SharePoint.Client.File.SaveBinaryDirect(m_clientContext, str_URLOfFile, fileStream, true);
Microsoft.SharePoint.Client.File fileUploaded = m_List.RootFolder.Files.GetByUrl(str_URLOfFile);
m_clientContext.Load(fileUploaded);
m_clientContext.ExecuteQuery();
User user1 = m_Web.EnsureUser("User1");
User user2 = m_Web.EnsureUser("User2");
ListItem item = fileUploaded.ListItemAllFields;
fileUploaded.CheckOut();
item["UserDefinedColumn"] = "UserDefinedValue1";
item["Title"] = "UserDefinedValue2";
item["Editor"] = user1;
item["Author"] = user2;
item.Update();
fileUploaded.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);
m_clientContext.ExecuteQuery();

Hi talib2608,
Chris is correct for this issue, when calling update using ListItem.update method, it will increase item versions, using SystemUpdate and UpdateOverwriteVersion will update the list item overwrite version.
these two methods are not available in CSOM/REST, only server object model is available for this.

Advanced permission for files and folders

Advanced permission for files and folders
Hi,
Just wanted to raise a quick query on setting a unique NTFS Security permission.
My requirement
A shared folder with the below listed access for users
A group of users should be able to create, read, rename files and folders inside a shared folder.
The group of users should not have the right to delete any folder or file from the shared folder.
This is what I have tried.
Gave modify permission to the Security group.
On Advanced permissions, denied delete subfolders and file & delete permission.
The effective permission for a user who is member of the security group over a file inside the shared folder is as shown.
https://onedrive.live.com/redir?resid=835A81FDD1D9D9FC!109&authkey=!AGQFP11QTFaLHQM&v=3&ithint=photo%2cpng
But while trying to rename or modify the file, getting the below error message.
https://onedrive.live.com/redir?resid=835A81FDD1D9D9FC%21110
Any help to achieve my requirement would be really appreciated.
Thanks,
JD

Hi JD,
Removing delete permission from the user or group brings a limitation that the user will not be able to rename the folder. This is because of the reason that the "rename" operation is also included within the "Delete" permission.
Thus if you want to prevent user from deleting the shared file, it's also not allowed to rename.

Unable to get the SharePoint 2013 List names using Client object model for the input URL

Please can you help with this issue.
We are not able to get the SharePoint 2013 List names using Client object model for the input URL.
What we need is to use default credentials to authenticate user to get only those list which he has access to.
clientContext.Credentials = Net.CredentialCache.DefaultCredentials
But in this case we are getting error saying ‘The remote server returned an error: (401) Unauthorized.’
Instead of passing Default Credentials, if we pass the User credentials using:
clientContext.Credentials = New Net.NetworkCredential("Administrator", "password", "contoso")
It authenticates the user and works fine. Since we are developing a web part, it would not be possible to pass the user credentials. Also, the sample source code works perfectly fine on the SharePoint 2010 environment. We need to get the same functionality
working for SharePoint 2013.
We are also facing the same issue while authenticating PSI(Project Server Interface) Web services for Project Server 2013.
Can you please let us know how we can overcome the above issue? Please let us know if you need any further information from our end on the same.
Sample code is here: http://www.projectsolution.com/Data/Support/MS/SharePointTestApplication.zip
Regards, PJ Mistry (Email: [email protected] | Web: http://www.projectsolution.co.uk | Blog: EPMGuy.com)

Hi Mistry,
I sure that CSOM will authenticate without passing the
"clientContext.Credentials = Net.CredentialCache.DefaultCredentials" by default. It will take the current login user credentials by default. For more details about the CSOM operations refer the below link.

Quering the database using Client Object Model

Hi,
I have to fetch the list items from a list named "Project Status" and display it in a table using
Client Object model.
The equivalent server side code is:
SPWeb web = SPContext.Current.Web;
SPList list = web.Lists["Project Status"];
DataTable dt1 = new DataTable();
try
if (list.ItemCount > 0)
DataColumn dc;
DataColumn dc1;
dc = new DataColumn("ProjectId", Type.GetType("System.String"));
dc1 = new DataColumn("Project Name", Type.GetType("System.String"));
dt1.Columns.Add(dc);
dt1.Columns.Add(dc1);
DataRow dr;
foreach (SPListItem item in list.Items)
dr = dt1.NewRow();
dr["ProjectId"] = item["ProjectId"];
dr["Project Name"] = item["Project Name"];
dt1.Rows.Add(dr);
Repeater1.DataSource = dt1;
Repeater1.DataBind();
catch (Exception Ex)
throw Ex;
1 more issue what i face is providing two links in the Visual WebPart and their navigate url is based on a condition that is fetched from the database. This corresponding code has to be converted to
Client Object Model.
string user = web.CurrentUser.LoginName;
string userID = user.Split(new char[] { '\\' })[1];
string connString = @"Data Source=NorthWind;Initial Catalog=EmployeeDB;User ID=sa;Password=Newuser123";
string query = "select * from EMPLOYEE_PROFILE";
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(query, conn);
try
conn.Open();
DataTable t1 = new DataTable();
using (SqlDataAdapter a = new SqlDataAdapter(cmd))
a.Fill(t1);
DataRow[] dr = t1.Select("PsNo = '" + userID + "'"); //This will select all rows where the Name Column has current user
foreach (DataRow r in dr)
string bU = r["DeputedBU"].ToString();
if (bU == "INS" || bU == "BFS")
lnkPM.NavigateUrl = web.Site.WebApplication.Sites[0].Url + "/Dashboard.aspx";
lnkSummary.NavigateUrl = web.Site.WebApplication.Sites[0].Url + "/DashboardWithHyperlinks.aspx";
else
lnkPM.Visible = false;
lnkSummary.Visible = false;
catch (Exception)
throw;
finally
conn.Close();
Any help would be appreciated.

Hi,
According to your post, there would be two questions in this single thread.
It is recommended to post one question in one single thread which will make others easier to focus on one question in one thread.
For the first question, you want to fetch list items and put into a DataTable object using Client Object Model.
To fetch list items from a list using Client Object Model, you can take a look at the code snippet below from MSDN:
http://msdn.microsoft.com/en-us/library/office/ee534956(v=office.14).aspx
For the second question, you might need to retrieve the User object and site collections object using Client Object Model.
However, if you can develop a Visual Web Part for your site, it means that you will be able to access the SharePoint Object Model which has more powerful APIs, so there is no
need to use Client Object Model in a Visual Web Part.

Assign Group permission to list item using client object model

Hi,
I am trying to add the list item and assign the permission to the list item by using SP 2010 client object model. The problem which i am facing that when i assign the group as a permission to the item, by automatically the limited access permission
is added to the group. Please find the steps which i have followed,
Step-1: Break role inheritance.
foreach (var item in _listItemCollection)
if (item["FileLeafRef"].ToString().ToLower() == "xxx")
item.BreakRoleInheritance(true, false);
_clientContext.Load(item.RoleAssignments);
_folderItem = item;
_clientContext.ExecuteQuery();
Step 2: Remove all permissions of the list item.
foreach (var assignment in _folderItem.RoleAssignments)
assignment.RoleDefinitionBindings.RemoveAll();
assignment.Update();
_clientContext.ExecuteQuery();
Step 3:
Add Group as a permission to the list item.
var role = _web.RoleDefinitions.GetByType(RoleType.Contributor);
var collRdb = new RoleDefinitionBindingCollection(_clientContext) { role };
Principal principal = _grp;
_folderItem.RoleAssignments.Add(principal, collRdb);
_folderItem.Update();
_clientContext.ExecuteQuery();
After adding the group successfully to the list item, i checked the group permission and it contains the value as "Contribute,Limited Access" to the site level and "Contribute" to the list item. Please guide me how to avoid to create Contribute,Limited
Access role.
Balaji

Hi Dmitry,
When I create the group and assign contribute permission, the group has the permission at the site level(to see the permission, click group and click view Group Permission). I have added the list item and break the role inheritance permission
and given the unique permission by providing group as a permission to the list item. After providing the permission, the group permission at the site level changed to "Contribute, Limited Access". I dont know how contribute permission changed to contribute,
limited access.
I found the workaround to fix this issue. I created the group and create the folder in the shared document library by using client object model. Due to facing some issue by providing the permission using client object model, i have created the event receiver
to the document library and using server object model, i can able to assign the approprate group permission.

Role Assignment Discovery Issue for Files and Folders through Sharepoint REST services

To preface, I am a decided Sharepoint newbie in every sense. I am trying to use the Sharepoint REST services (Sharepoint 2013) to walk the folder and file structure of my Sharepoint server and, determine as I go, the Role Assignments (and subsequently
Permissions) on those folders and files. I'm using an Administrator credentials and I'm actually able to successfully do it but I've run into some caveats. All the caveats begin with this; when I'm examining a folder, for example:
/_api/Web/GetFolderByServerRelativeUrl('/sites/cmisdev/Development')/ListItemAllFields
I receive either an empty list or an error response doc when following the link supplied for ListItemAllFields. When following that kind of link for folders, I either get:
<d:ListItemAllFields
m:null="true"
/>
or an error response document that says "The object specified does not belong to a list." When I hit the /ListItemAllFields endpoint for files, I receive a response with a link for Role Assignments which subsequently also works and I get the
info I need. So, is this a bug? Why does the link returned from Sharepoint work for files and not folders? So, google, google, google, and I discover that there is another possible way to get at the Role Assignments (and that the object does, indeed, belong
to a list!).
If I know the Title (or the guid) of the folder in question, I can use the following endpoint:
/_api/Web/Lists/GetByTitle('Development')
If I use that endpoint, I get the information I would have expected to get from following /ListItemAllFields and the subsequent Role Assignments links all work and I get what I need. If there's a bug and this is how I have to work around it, that's fine
but I have yet to discover how to dynamically determine the Title of a given folder nor am I sure if all Titles are supposed to be unique within a given Sharepoint server. I'm assuming that the folder name as represented in the server relative URL and the
Title may be different and this is where my newbishness may start to shine if I'm misunderstanding what a "List" is supposed to be in Sharepoint. Anyway, I did find that I could use the Properties endpoint to perhaps get the Title, for example:
/_api/Web/GetFolderByServerRelativeUrl('/sites/cmisdev/Development')/Properties
gives me:
<d:vti_x005f_listtitle>Development</d:vti_x005f_listtitle>
whose value I assume I could then supply to the /GetByTitle endpoint and be golden. However, "vti_x005f_listtitle" just sounds a little too deep to be something I should be relying on but maybe that's kosher. That's part of what I'm trying to
find out. Also, if there is a way to use the Sharepoint REST API to discover the guid of a given object, then I could look it up in that way.
So, in summary:
1. Am I going about getting folder Role Assignment information in the wrong way? Based on the CSOM examples I've seen, I believe I'm doing it correctly and that the answer to #2 below is a resounding "Yes!" :)
2. Is it a bug if I'm not able to use /ListItemAllFields on folders using the server relative url?
3. If I'm supposed to use GetByTitle as a workaround, am I discovering that Title correctly through /Properties? Seems quite circuitous and awkward. Are Titles required to be unique throughout a given Sharepoint server?
4. If I'm supposed to use the guid, how can I use the REST interface to discover an object's guid? Once we get down to the Role Assignments and other links, the guid appears in those links but I don't know how to discover it independently if that's the
path I should use to get the data I described above.

Upon further research, I'll answer my own question for the benefit of some other potential future newbie. The answer to question number 1 above is "Not exactly.". The server relative URLs I was using corresponded to lists (which are
returned as a collection through /_api/web/lists). I was treating them mentally like regular folders. That, coupled with the fact that accessing their data as I showed above returns a ListItemAllFields link, made me think that was the way to get
the Role Assignments just as I would for files and, as it turns out, "real" folders and sub-folders created under these lists. That was the other problem with thinking of these lists as regular folders. So, ListItemAllFields works on
all files and folders in a list. However, if you want Role Assignments for the lists themselves, you can keep track of the Titles and\or Guids from the /_api/web/lists that you're interested in (in my case, all non-hidden "document library"
type lists) and then access those Role Assignments as I discussed in questions 3 and 4 above. For example, from the /_api/web/lists collection from my test server, the "Development" document library Role Assignments are accessable via /_api/Web/Lists(guid'cd242eeb-aafa-4efa-aecc-9bbdf8e3d459')/RoleAssignments
or /_api/Web/Lists/GetByTitle('Development')/RoleAssignments.

Is it possible to change the title of a webpart using client object model/c#/sharepoint online

Hi folks!
I have been busted my butt trying to Write a program changing the title of an existing webpart on on of our subsites on SharePoint online. But I keep getting an error in the very last context.executequery. Tried a bunch of different approaches, but I can't
make it work. Before I start posting code; I Wonder if anyone have ever done this?
Its a plain Windows form application, using Visual studio Express and the Client Object model. (Listsing the titles of the webparts Works but changing titles seem impossible. Thought it might be a checkin/out problem but it doesn't make a difference).
Any help would be highle appreciated.
Lars

It depends: are you using the default style for Text Captions? In that case you can change the default style in the Object Style Manager and have it applied to all Captions.
Or you can change one text caption, and in its Properties panel choose the option 'Save Changes to existing style' from the menu top right (see screenshot). Both methods will work if you didn't override the default Caption Style for those captions. Beware: Quizzing objects can use another style.

Any Simple Way to check wheter the user is belongs to SharePoint Group in Client object model

Hi All,
Generally we follow these steps to check whether user belongs to this perticular group:
1.Get the "Group" object from the Group Collection based on the group name
2.Get all UserCollection from the "Group" object
3.Take a loop and check with each user object (eg User.ID="777473844")
I am thinking this is time taking process( if group has more than 100 members).
Do we have any shortway to check whether user is belongs to this perticular SharePoint Group?
Thanks in Advance!
Thanks,
Mahesh Yamana
Mahesh@SharepointSolutions

Hi Mahesh,
Below is a CSOM JS code to check whether a user belongs to a group. We get the current user object, and then the list of Groups which the user is part of. And then check if the required group is present or not in the collection.
function retrieveWebSite() {
var clientContext = new SP.ClientContext.get_current();
this.oWebsite = clientContext.get_web();
this.oCurrentUser = this.oWebsite.get_currentUser();
this.oUserGroups = this.oCurrentUser.get_groups();
clientContext.load(this.oUserGroups);
clientContext.executeQueryAsync(
Function.createDelegate(this, this.onQuerySucceeded),
Function.createDelegate(this, this.onQueryFailed)
function onQuerySucceeded(sender, args) {
var Group1 = "Group Name One";
var Group2 = "Group Name Two";
var flag = false;
var iCount = this.oUserGroups.get_count();
for(var i=0; i<iCount; i++)
oGroup = this.oUserGroups.getItemAtIndex(i);
if(oGroup.get_title() != Group1 && oGroup.get_title() != Group2)
flag=true;
else
flag=false; break;
if(flag == true)
//Write your logic here
function onQueryFailed(sender, args) {
