I'm attempting to create a feature stapled solution that pushes out custom branding to every new site collection created. The following code is in my event receiver: 

 public override void FeatureActivated(SPFeatureReceiverProperties properties) { using(SPSite sitecollection = properties.Feature.Parent as SPSite) { using (SPWeb site = sitecollection.OpenWeb()) { foreach (SPWeb web in sitecollection.AllWebs) { try { SPList list = web.Lists.TryGetList("Composed Looks"); foreach (SPListItem item in list.Items) { if(item.Title != "Current" || item.Title != "Dynetics") { item.Delete(); item.Update(); } } } finally { if(web != null) { web.Dispose(); } } } } } }

But when deploying the solution I get the error: 

Error occurred in deployment step 'Activate Features': Item does not exist. It may have been deleted by another user.

WHY??

Reset to default

By looking into your code, i think the problem is 

item.Delete(); item.Update();

You are updating item after you are deleting, there is no need to update the item after delete.

You can not update a deleted item.

  • Ok that got rid of the original error, but now I receive: Collection was modified; enumeration operation may not execute. Commented May 28, 2014 at 17:08
  • use for (int i = items.Count - 1; i >= 0; i--) { SPListItem item = items[i]; item.Delete(); } Commented May 28, 2014 at 17:21
  • you are getting this error because You can not modify a collection while enumerating it because the iterator will reset and you will have exception.I Commented May 28, 2014 at 17:23
  • Or you can maintain a list of listitems to delete and delete them one by one after your foreach statement. Commented May 28, 2014 at 17:27
