To save a user name into a people field

To save a user name into a people field:

Provided a people editor control in my custom form and saved each resolved entity as follows:

 if (currentPeopleEditor.Entities.Count != 0)
 {
 SPFieldUserValueCollection userCollection = new SPFieldUserValueCollection();
 for (int index = 0; index < currentPeopleEditor.ResolvedEntities.Count; index++)
 {
  PickerEntity ObjEntity = (PickerEntity)currentPeopleEditor.ResolvedEntities[index];
  userCollection.Add(new SPFieldUserValue(objSPWeb,Convert.ToInt32(ObjEntity.EntityData["SPUserID"]), ObjEntity.Key));
  }
  newItem[Field.Key.ToString()] = userCollection;
  }

It was working very fine until some user stated getting this exception: "Invalid Look-up Value

A look-up field contains invalid data, Please check the value and try again."

On investigating we found that this error was occurring because ObjEntity.EntityData["SPUserID"]) was returning as null.

It was happening because the requirement is to save some users name who don't access this site collection but they are member of corporate AD system.

Solution

  • Long story short to resolve above problem in SharePoint 2010 just use web.EnsureUser()

    It adds user to the all user list and returns spuser object.
