Can't delete a featureclass in file GDB

[QuinnMcCarthy]

I have a FC in a in a file GDB that I can't belete. When I use the context menu delete and rename options are grayed out. I tried the delete button the the same thing. I tried getting out of arc catalog and getting back in and still the same problem. I tried rebooting twice and still can't delete.

I am not sure what I should try next?

thanks

Is the Feature Class in a Geometric Network, Network Dataset or Topology?

[QuinnMcCarthy]

It is part of a topology.

DIdn't even think of that.

Thanks
