Cell|Format Issue

I make my Excel on the fly from Aspose.Excel. There are a number of styles made in the code and these styles are assigned to cells.

The sheet looks fine when it is built, but I am unable to select Format|Cells (or Ctrl-1) in Excel on any cell that I have made. Other cells (outside the range I created) I can do Format|Cells.

Is this expected?

Could you please send your code and created file to me? I will check this issue right now.

Thanks for the quick response.

I will need to factor out all the SQL Server stuff, etc. and get you a pared down version. I'll get you a sample as soon as I can; probably not before Thursday US time.
