I am working on SharePoint 2016 CSOM to get list item version history. unfortunately i am not getting the field values. please find the code below.
var file = item.File;
var versionFiles = file.Versions;
var fa = file.ListItemAllFields;
clientContext.Load(fa);
clientContext.Load(file);
clientContext.Load(versionFiles);
clientContext.ExecuteQuery();
if (null != versionFiles)
{
var fileVersion = file.Versions[5];
SP.File oldFile =web.GetFileByServerRelativeUrl("/sites/site/_vti_history/1234/list1/file1.pdf");
var allField = oldFile.ListItemAllFields;
clientContext.Load(allField);
}
You could get version history metadata from Lists.asmx.
Sample code:
var web = clientContext.Web;
List spList = clientContext.Web.Lists.GetByTitle("MyDoc");
var item = spList.GetItemById(43);
clientContext.Load(spList);
clientContext.Load(item);
clientContext.ExecuteQuery();
#region customList
Lists.Lists listService = new Lists.Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
listService.Url = siteUrl + "/_vti_bin/lists.asmx";
XmlNode nodeAttachments = listService.GetVersionCollection(spList.Id.ToString(), item.Id.ToString(), "Title");
foreach (System.Xml.XmlNode xNode in nodeAttachments)
{
Console.WriteLine(xNode.Attributes["Title"].Value);
}

I am getting a "Version conflict" error while trying to update a list item via CSOM.
Code:
String webUrl = <Your Weburl>;
String path = row["Path"].ToString();
String listTitle = null;
try
{
using (ClientContext ctx = new ClientContext(webUrl))
{
ctx.Credentials = new SharePointOnlineCredentials(tenantsitelogin, password);
listTitle = "Pages"; // path.Substring(0, path.LastIndexOf("/")).Substring(webUrl.Length + 1);
var list = ctx.Web.Lists.GetByTitle(listTitle);
var listItem = list.GetItemById(184);
ctx.Load(list);
ctx.Load(listItem, i => i.File);
var file = listItem.File;
ctx.Load(file, x => x.Versions);
ctx.ExecuteQuery();
file.UnPublish("Some Comment");
listItem.Update();
ctx.ExecuteQuery();
//ctx.Web.Lists.GetByTitle(listTitle);
}
}
Need to resolve the "Version conflict" error.
Remove following line from your code to resolve “Version conflict.” error
listItem.Update();
I'm using C# and CSOM to build an application that creates an event in a SharePoint calendar that I know exists in my O365 subscription. I know O365 is SharePoint 2013, but my application targets SharePoint 2010, so I'm going to have to deal with both versions.
No exceptions are thrown and everything appears to succeed, but the new event does not display in the calendar, even after a page refresh. If I get a collection of items with the same event title, the program-entered event is returned, and appears to contain all the columns set in code.
The CalendarItemCreate function puts data in all the required columns of the calendar. If I search for other calendar items I have hand-entered through the SharePoint calendar, I find them. The only difference I can see between either hand-entered or program-entered events is the "Description" column has ' for the hand-entered events.
Any ideas?
private void CalendarItemCreate(ICalendarItem item) {
using (var context = new ClientContext(_calendarLocation)) {
context.Credentials = _credentials;
var web = context.Web;
var transferScheduleList = web.Lists.GetByTitle(TransferScheduleToken);
var listItemCreationInformation = new ListItemCreationInformation();
var listItem = transferScheduleList.AddItem(listItemCreationInformation);
listItem[TitleToken] = item.EventTitle;
listItem[EventDateToken] = item.EventStartLocal;
listItem[EndDateToken] = item.EventStartLocal.AddMinutes(30);
listItem[DescriptionToken] = string.Empty; //item.EventDescription;
listItem[TransferTypeToken] = item.EventTransferType;
listItem[TransferStatusToken] = item.EventTransferStatus;
listItem[CategoryToken] = "Data Transfer";
listItem[ConfigurationFileLocationToken] = item.ConfigurationFileLocation;
listItem[EventTypeToken] = 0;
listItem[FallDayEventToken] = false;
listItem[FrecurrenceToken] = false;
listItem.Update();
context.ExecuteQuery();
}
The solution was a combination of formatting the dates as strings that SharePoint could understand and data type mismatches in two of my transfer columns. The code below was successful.
using (var context = new ClientContext(_calendarLocation)) {
context.Credentials = _credentials;
var web = context.Web;
var transferScheduleList = web.Lists.GetByTitle(TransferScheduleToken);
var listItemCreationInformation = new ListItemCreationInformation();
var listItem = transferScheduleList.AddItem(listItemCreationInformation);
listItem[TitleToken] = item.EventTitle;
listItem[EventDateToken] = item.EventStartLocal.ToUniversalTime().ToString(#"yyyy-MM-ddTHH:mm:ssZ");
listItem[EndDateToken] = item.EventStartLocal.AddMinutes(30).ToUniversalTime().ToString(#"yyyy-MM-ddTHH:mm:ssZ");
listItem[DescriptionToken] = item.EventDescription;
listItem[TransferTypeToken] = item.EventTransferType.ToString();
listItem[TransferStatusToken] = item.EventTransferStatus.ToString();
listItem[CategoryToken] = "Data Transfer";
listItem[ConfigurationFileLocationToken] = item.ConfigurationFileLocation;
listItem[EventTypeToken] = 0;
listItem[FallDayEventToken] = false;
listItem[FrecurrenceToken] = false;
listItem.Update();
context.ExecuteQuery();
using (ClientContext clientContext = new ClientContext("URLSHAREPOINT"))
{
SecureString passWord = new SecureString();
foreach (char c in "PASSWORD".ToCharArray()) passWord.AppendChar(c);
clientContext.Credentials = new SharePointOnlineCredentials("USERNAME.onmicrosoft.com", passWord);
Web web = clientContext.Web;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = System.IO.File.ReadAllBytes(#"FILELOCATION");
newFile.Url = "file uploaded via client OM.txt";
List docs = web.Lists.GetByTitle("LIBRARYNAME");
Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
clientContext.ExecuteQuery();
}

var Nome = docList.Fields.GetByTitle("METADATANAME").InternalName;
var Posicao = docList.Fields.GetByTitle("METADATANAME").InternalName;

I need to create subfolder in sharepoint with client object model, the parent folder is existing, this is my code, but I got this error,
Invalid file name.
The file name you specified could not be used. It may be the name of an existing file or directory, or you may not have permission to access the file.
ContentTypeCollection listContentTypes = list.ContentTypes;
clientContext.Load(listContentTypes, types => types.Include
(type => type.Id, type => type.Name,
type => type.Parent));
var result = clientContext.LoadQuery(listContentTypes.Where
(c => c.Name == "Folder"));
clientContext.ExecuteQuery();
ContentType folderContentType = result.FirstOrDefault();
ListItemCreationInformation newItem = new ListItemCreationInformation();
newItem.UnderlyingObjectType = FileSystemObjectType.Folder;
newItem.FolderUrl = #"http://mysite/sites/org" + "/" + listName;
if (!folderName1.Equals(string.Empty))
{
newItem.FolderUrl += "/" + folderName1;
}
newItem.LeafName = folderName2;
ListItem item = list.AddItem(newItem);
item["ContentTypeId"] = folderContentType.Id.ToString();
item["Title"] = folderName2;
item.Update();
clientContext.Load(list);
clientContext.ExecuteQuery();
If you need to create folder you can try to use the following code:
using (var clientContext = new ClientContext(#"http://server"))
{
var web = clientContext.Web;
var lst = web.Lists.GetByTitle("CheckDocLib");
var fld1 = lst.RootFolder.Folders.Add("FirstLevel1");
var fld2 = fld1.Folders.Add("SecondLevel1");
fld1.Update();
fld2.Update();
clientContext.ExecuteQuery();
}
Does anyone know how to read the number of attachments, and the names etc for a ListItem using the Client .Net Object model in SharePoint?
Thanks
// For getting the list item field information
public void LoadPropertyInfo()
{
using (context = new ClientContext(siteCollectionUrl))

context.Load(fields);
SP.CamlQuery query = new SP.CamlQuery();

listItems = propertiesList.GetItems(query);
context.Load(listItems);
context.ExecuteQueryAsync(GetRequestSucceeded, RequestFailed);
}
}
// Pass the item id here for getting the attachments
private void GetAttchmentCollection(string id)
{
string RedirectHost = string.Empty;
string Host = string.Empty;
context = SP.ClientContext.Current;

BasicHttpBinding binding = new BasicHttpBinding();
if (System.Windows.Browser.HtmlPage.Document.DocumentUri.Scheme.StartsWith("https"))
{
binding.Security.Mode = BasicHttpSecurityMode.Transport;
}
binding.MaxReceivedMessageSize = int.MaxValue;
EndpointAddress endpoint = new EndpointAddress(RedirectHost);
ServiceReference1.ListsSoapClient oClient = new ServiceReference1.ListsSoapClient(binding, endpoint);
oClient.GetAttachmentCollectionCompleted += new EventHandler<ServiceReference1.GetAttachmentCollectionCompletedEventArgs>(oClient_GetAttachmentCollectionCompleted);
oClient.GetAttachmentCollectionAsync(listName, id);
}
