Hi,

Thanks for considering Aspose.

Well, you are using some older version i.e. Aspose.Excel.Web. Could you try the latest version Aspose.Grid.Web 1.9.2. downloading @:

For your info, Aspose.Excel.Web has been renamed to become Aspose.Grid.Web now which is more stable and feature rich control.

Thank you.
