Is there a way via the API to change the Sheet Index Name?
Jon is correct. We now haven't Sheet Index related API published. I had filed an enhancement for it months ago as below:
Enhancement 1048943:Sheet Index API needed
Is there any update on if this will be added to the .NET API?
Hi Mike Robertson,
I linked the two enhancements below (having some overlapping functionality requested) and will check with product management to see if this can be addressed in MSCE U15 or need to be deferred for U16. Until the API becomes available please see this post for the most recent information and request to publish an internal Sheet Manager API for .NET.
