Its not the TreeItem which is null, it could be vcs or teamProject which is null. Put a break point and hover over vcs or teamProject and see which is null.

VersionControlServer vcs = (VersionControlServer)tfs.GetService(typeof(VersionControlServer)); – user1536577 Jul 20 '12 at 09:23
@user1536577, that can still be null – Habib Jul 20 '12 at 09:25
tfs isn't NULL,whai 's problem about GetService(typeof(VersionControlServer))??? – user1536577 Jul 20 '12 at 09:29
@user1536577, I am not sure, probably because you don't have any service of type VersionControlServer – Habib Jul 20 '12 at 09:30

Your vcs probabbly is Null or it's teamProject, don't see any other possibility.

Check it out.

Debug the program.
