CellsException: A workbook must contain at least a visible worksheet

Hi Aspose Team,


When I try to upload a password protected excel in my application it gives following exception.


CellsException: A workbook must contain at least a visible worksheet.


My application has following lines of code:


objwork = new Aspose.Cells.Workbook(filepath, loadOptions);

objwork.Decrypt(password);

objwork.Protect(Aspose.Cells.ProtectionType.None, password);

objwork.Save(FilePath); //The exception is caught when the code execution reaches this line


Kindly look into the matter.

Thanks,

VED
