Update document set item programmatically

Question

In the code below I am getting the following Exception :

 Unhandled Exception: Microsoft.SharePoint.SPException: The file Audit/0003 has been modified by contoso\sp_install.

Does the file need to be checked out first? Anyone has got any idea how to solve this? I can't seem to find example on how to add an item to a document set.

SPList list = web.Lists.TryGetList("Audit");
DocumentSet docSet = CreateDocumentSet(list, au.Guid);
SPListItem docSetItem = docSet.Item;

if (list != null)
{
    docSetItem["A1_1_Question"] = au.A1_1_Question;
    docSetItem["A1_2_Question"] = au.A1_2_Question;
    docSetItem.Update();
}

public static DocumentSet CreateDocumentSet(SPList list, string DocumentSetName)
{
    SPContentType docsetCT = list.ContentTypes["Audit"];

    Hashtable properties = new Hashtable();
    properties.Add("DocumentSetDescription", "New Document Set");
    SPFolder parentFolder = list.RootFolder;
    DocumentSet docSet = DocumentSet.Create(parentFolder, DocumentSetName, docsetCT.Id, properties, true);
    return docSet;
}

Please check the internal name or static name of the fields you are updating. This might cause issue.

If Checkout is required in the document then you have to Checkout the item before updating and Checkin after updating.

item.CheckOut();
item.Update();
item.CheckIn();

Also check following:

I tried to use the checkout method, but there is no such method in the documentSet. – Imir Hoxha Jun 11 '14 at 13:52
use docSetItem.Checkout() not on document set. – Aanchal Jun 11 '14 at 13:53
yes, I used it in the docSetItem.CheckOut() but this method does not exist – Imir Hoxha Jun 11 '14 at 13:56
Ok Try docSetItem.SystemUpdate(false) or add some Thread.Sleep beforedocStItem.Update() – Aanchal Jun 11 '14 at 13:58
I still get the exception of being modified by me. – Imir Hoxha Jun 11 '14 at 14:10
Try web.AllowUnsafeUpdates = true; before updating. – Aanchal Jun 11 '14 at 14:17
Also try docSet.Item.UpdateOverVersion – Aanchal Jun 11 '14 at 14:19
I used docSet.Item.UpdateOverVesion but I am still getting the exception: Unhandled Exception: Microsoft.SharePoint.SPException: The file AuditSIPP/0012 has been modified by contoso\sp_install – Imir Hoxha Jun 12 '14 at 07:46

Thanks to this Post I was able to solve my issue. this is the code that I used:

DocumentSet newDc = DocumentSet.Create(folder, "Docset", docsetCT.Id, properties, true);

DocumentSet MyDocSet = DocumentSet.GetDocumentSet(list.GetItemById(newDc.Item.ID).Folder);

MyDocSet.Item["MyField"] = "Test";
MyDocSet.Item.Update();
