I am adding a site column into a document library default view and want it to be visible/shown when you click onto the list itself. However, I am unsure on how to do this. The code I have so far
// Get the view (this is the default view)
Microsoft.SharePoint.Client.View v = Employeecvlist.GetViewByName("All Documents");
// Load it up
clientContext.Load(v, x => x.ViewFields);
clientContext.ExecuteQuery();
// Get the field I want to add to the view
Microsoft.SharePoint.Client.Field name =
Employeecvlist.Fields.GetByInternalNameOrTitle("Name");
clientContext.Load(name);
clientContext.ExecuteQuery();
// Add this field to the view !! Nothing else in the view object to allow to make it visible by default !!
v.ViewFields.Add(name.InternalName);
// Finally, update the view
v.Update();
If you look at the image file below, I basically want to be able to check the "display" checkbox to true for the above field.
Can someone point me into the right direction?
Thanks
You need to perform clientContext.ExecuteQuery() again to persist the changes. Also, there's no need to do it twice to load your objects, load everything you need and then get it from the server:
//Put following line in the using section
using Microsoft.SharePoint.Client;
//Your code
View v = Employeecvlist.GetViewByName("All Documents");
Field name = Employeecvlist.Fields.GetByInternalNameOrTitle("Name");
clientContext.Load(v, x => x.ViewFields);
clientContext.Load(name);
v.ViewFields.Add(name.InternalName);
v.Update();
clientContext.ExecuteQuery();

I've got a view control which opens an xpage. When the xpage opens, the beforePageLoad event fires. It checks to see if there are any attachments in a particular field of the document being opened and if there are, it returns list of the filenames. This was working fine. Then, I was asked to change what's displayed in one of the columns of the view. I added a variable to the view control's data section to access the row. I then added some javascript to the column to display the data differently. That worked and it displayed the data as wanted. However, when I now click on the link to open the xpage, when the beforePageLoad event fires, the code that's there now fails. It fails with this error at the starred line:
Script interpreter error, line=9, col=49: 'closureField' is null at
[/Function_ReturnListOfClosureAttachmentNames.jss].ReturnListOfClosureAttachmentNames(CCEB1351591847CB85257E7C005EF68C)
function ReturnListOfClosureAttachmentNames(ltDoc ){
var closureAttachmentFileNames = "";
var thisLT = ltDoc;
var closureField:NotesRichTextItem = thisLT.getFirstItem("closeAttachments");
*>>> var eos:java.util.Vector = closureField.getEmbeddedObjects();<<<
var eosi:java.util.Iterator = eos.iterator();
while (eosi.hasNext()) {
var eo:NotesEmbeddedObject = eosi.next();
closureAttachmentFileNames = closureAttachmentFileNames +","+eo.getName();
}
return closureAttachmentFileNames;
}
I call this function from the beforePageLoad event and pass it currentDocument.getDocument(). I think I might have lost the document context after changing the column display data from 'view column' to 'computed value' but I'm not sure. Any ideas would be appreciated.
thanks!

Figured it out: When I assigned a variable to the view, when you click on a linked column in that view, it loads the current ViewEntry into the context and not a current document. So I put the unid of the doc from the selected ViewEntry in an application scope variable and returned it to the Document Id property when I open the xPage. I have to now update all my views but there aren't too many luckily. Thanks for working through this with me!
Clem –
I start from a TableView to create and store user information. This is how I create a core data entity called "Trials" in CreateTrialViewController. And I can successfully fetch it in the tableViewController after I come back to it.
let trial : Trials = NSEntityDescription.insertNewObjectForEntityForName("Trials", inManagedObjectContext: self.managedObjectContext!) as? Trials
{
trial.project = theProject.text
trial.record = theRecord.text
trial.notes = theNotes.text
trial.percentile = ""
managedObjectContext?.save(nil)
}
'
But after I create the Trial, I will get some calculated results from the accelerometer in the next measureViewController, and I want to save the result into 'trial.percentile'.
I have already converted the results into a string, so I can write it directly into the core data attribute. But how can I know the index of this core data that I just created? Should I try to use 'segue' to transmit?
In the tableView it fetches in a ascending sequence of date, so the index is clear. But here in the following VC how to know the index? I still couldn't figure this out by myself... The sequence of my VCs is: TableViewController -> CreateTrialViewController -> MeasureViewController -> TableViewController (start again)
Your table view controller can keep a reference to the newly created object. Insert the object (trial) in the original view controller and pass it on to the next controller in prepareForSegue. So the CreateTrialViewController starts out with a blank object to which the table view controller has a reference.
You configure the object, go to the measure controller, modify the object. When done, you pop these two controllers from the navigation stack and are back in your original table view controller.
Because your table view controller has the NSFetchedResultsControllerDelegate enabled, it will update itself to reflect the data of your new object. Remember, you still have a reference to this object, so you can just use indexPathForObject to retrieve its index path.
I created an ActivityNode (an Entry) and I can add custom fields with the
setFields(List<Field> newListField)
fonction.
BUT
I am unable to modify these fields. (In this case I try to modify the value of the field named LIBENTITE)
FieldList list = myEntry.getTextFields();
List<Field> updatedList = new ArrayList<Field>();
//I add each old field in the new list, but I modify the field LIBENTITE
for(Field myField : list){
if(myField.getName().equals("LIBENTITE")){
((TextField)myField).setTextSummary("New value");
}
updatedList.add(myField);
}
myEntry.setFields(updatedList);
activityService.updateActivityNode(myEntry);
This code should replace the old list of fields with the new one, but I can't see any change in the custom field LIBENTITE of myEntry in IBM connections.
So I tried to create a new list of fields, not modifying my field but adding a new one :
for(Field myField:list){
if(!myField.getName().equals("LIBENTITE")){
updatedList.add(myField);
}
}
Field newTextField = new TextField("New Value");
newTextField .setFieldName("LIBENTITE");
updatedList.add(newTextField );
And this code is just adding the new field in myEntry. What I see is that the other custom fields did not change and I have now two custom fields named LIBENTITE, one with the old value and the second with the new value, in myEntry.
So I though that maybe if I clear the old list of Fields, and then I add the new one, it would work.
I tried the two fonctions
myEntry.clearFieldsMap();
and
myEntry.remove("LIBENTITE");
but none of them seems to work, I still can't remove a custom field from myEntry using SBT.
Any suggestions ?
I have two suggestions, as I had (or have) similar problems:
If you want to update an existing text field in an activity node, you have to call node.setField(fld) to update the field in the node object.
Code snippet from my working application, where I'm updating a text field containing a (computed) start time:
ActivityNode node = activityService.getActivityNode(id);
node.setTitle(formatTitle()); // add/update start and end time in title
boolean startFound = false;
// ...
FieldList textfields =node.getTextFields();
Iterator<Field> iterFields = textfields.iterator();
while (iterFields.hasNext()) {
TextField fld = (TextField) iterFields.next();
if (fld.getName().equals(Constants.FIELDNAME_STARTTIME)) {
fld.setTextSummary(this.getStartTimeString()); // NOTE: .setFieldValue does *not* work
node.setField(fld); // write updated field back. This seems to be the only way updating fields works
startFound=true;
}
}
If there is no field with that name, I create a new one (that's the reason I'm using the startFound boolean variable).
I think that the node.setField(fld) should do the trick. If not, there might be a way to sidestep the problem:
You have access to the underlying DOM object which was parsed in. You can use this to tweak the DOM object, which finally will be written back to Connections.
I had to use this as there seems to be another nasty bug in the SBT SDK: If you read in a text field which has no value, and write it back, an error will be thrown. Looks like the DOM object misses some required nodes, so you have to create them yourself to avoid the error.
Some code to demonstrate this:
// ....
} else if (null == fld.getTextSummary()) { // a text field without any contents. Which is BAD!
// there is a bug in the SBT API: if we read a field which has no value
// and try to write the node back (even without touching the field) a NullPointerException
// will be thrown. It seems that there is no value node set for the field. We
// can't set a value with fld.setTextSummary(), the error will still be thrown.
// therefore we have to remove the field, and - optionally - we set a defined "empty" value
// to avoid the problem.
// node.remove(fld.getName()); // remove the field -- this does *not* work! At least not for empty fields
// so we have to do it the hard way: we delete the node of the field in the cached dom structure
String fieldName = fld.getName();
DeferredElementNSImpl fldData = (DeferredElementNSImpl) fld.getDataHandler().getData();
fldData.getParentNode().removeChild(fldData); // remove the field from the cached dom structure, therefore delete it
// and create it again, but with a substitute value
Field newEmptyField = new TextField (Constants.FIELD_TEXTFIELD_EMPTY_VALUE); // create a field with a placeholder value
newEmptyField.setFieldName(fieldName);
node.setField(newEmptyField);
}
Hope that helps.
Just so that post does not stay unanswered I write the answer that was in a comment of the initial question :
"currently, there is no solution to this issue, the TextFields are read-only map. we have the issue recorded on github.com/OpenNTF/SocialSDK/issues/1657"
I seem to be having a problem with assigning values to fields of a content item with a custom content part and the values not persisting.
I have to create the content item (OrchardServices.ContentManager.Create) first before calling the following code which modifies a field value:
var fields = contentItem.As<MyPart>().Fields;
var imageField = fields.FirstOrDefault(o => o.Name.Equals("Image"));
if (imageField != null)
{
((MediaLibraryPickerField)imageField).Ids = new int[] { imageId };
}
The above code works perfectly when against an item that already exists, but the imageId value is lost if this is done before creating it.
Please note, this is not exclusive to MediaLibraryPickerFields.
I noticed that other people have reported this aswell:
https://orchard.codeplex.com/workitem/18412
Is it simply the case that an item must be created prior to amending it's value field?
This would be a shame, as I'm assigning this fields as part of a large import process and would inhibit performance to create it and then modify the item only to update it again.
As the comments on this issue explain, you do need to call Create. I'm not sure I understand why you think that is an issue however.
I have a webpart that works off of a list but what I'm trying to do create a dropdown that contains a list of sharepoint lists so that when the user edits the page and selects 'modify shared webpart' they are able to choose a list item and that gets parsed back to the webpart.
Any examples or links to examples appreciated!
Thanks

What you are looking for is called a Toolpart. Take a look at this example for a tutorial on how to create one.
Overall, your general steps will be:
Create your custom Toolpart class inheriting from Microsoft.SharePoint.WebPartPages.ToolPart
In your custom Toolpart, override CreateChildControls, write the code to iterate over the lists in your SPWeb, and add those to a DropDownList
In your webpart, override GetToolParts and add your custom ToolPart so that it shows up in the right hand side
It sounds like you want to create a custom editor part. In the part you would have one dropdown that shows the names of the lists (you probably want to filter hidden and empty lists) and, when an item is selected from the list, a second dropdown shows the Title column of the items from the selected list.
Here's some code (edited here, so it will need to be cleaned up) to help you get started:
protected Page_Load(...)
{
if (IsPostBack) return;
var web = SPContext.Current.Web;
var query = from list in web.Lists
where list.Hidden == false && list.ItemCount == 0
select list;
DropDownList1.DataSource = query;
DropDownList1.DataTextField = "Title";
DropDownList1.DataBind();
}
protected DropDownList1_SelectedIndexChanged(...)
{
var web = SPContext.Current.Web;
var listName = DropDownList1.Text;
var list = web.Lists[listName];
var table = list.Items.GetDataTable();
DropDownList2.DataSource = table;
DropDownList2.DataTextField = "Title";
DropDownList2.DataValueField = "ID";
DropDownList2.DataBind();
}
