I have a service that takes a file from a library and send it to an already specified folder.

This becomes a problem when I'm having files with same names on diferent folders.

Lets say that the event sends files to folder X, and I have fileA on folder A and also a fileA but this one on folder B.

What happens is that the folder X will recieve the first fileA, and then will replace the first one with the second!

I'm trying to do it as a ItemAdding event to change the file name on folder X so I can have the 2 files on this folder. Possibly fileA and fileA_2.

But how can I get the file that is being moved, if properties.ListItem returns null?


edit: here is the code I was trying to do:

public override void ItemAdding(SPItemEventProperties properties)

           if (properties.ListItem != null && properties.ListItem["Name"] != null)
               SPListItem currItem = properties.ListItem;
               string oldName = currItem["Name"].ToString();

               foreach (SPListItem item in properties.ListItem.ParentList.Items)
                   if (item.Name.Equals(oldName))
                       currItem["Name"] += "_1";
                       properties.Web.AllowUnsafeUpdates = true;
                       EventFiringEnabled = false;
                       properties.Web.AllowUnsafeUpdates = false;
                       EventFiringEnabled = true;


You can get URL of the file being added with properties.AfterUrl in ItemAdding event.


Check whether the specified file exists and if the file already exists cancel the event. That's the best you can do in ItemAdding event AFAIK.

  • that helps a lot, but instead of canceling the event, is there a way to change the name of the file to be moved? – smith Nov 11 '14 at 17:17
  • Can you edit your post and include code from event that is doing the copying? – Slaven Semper Nov 11 '14 at 22:52
  • I added the code. – smith Nov 12 '14 at 14:19
  • I was referring to initial event that does the copying of the file, not the one where you tried to rename destination file name. You said in your post: "Lets say that the event sends files to folder X, and I have fileA on folder A and also a fileA but this one on folder B." – Slaven Semper Nov 12 '14 at 14:49
  • I'm pretty much just using file.MoveTo(string,bool) after changing some custom properties. – smith Nov 12 '14 at 14:55
