You should reconsider using of excel's automation in .NET web application, see here why (in short it's not intended to be use on server side and you can encounter a lot of unexpected issues). Instead you could try out a C# component for excel's processing, which is safe to use in ASP.NET environment.

The question is tagged with "WPF", but the provided answer is for ASP.NET's GridView control, so I'm not sure which GridView control are you referring to.
Nevertheless I would suggest you to check out this C# library for excel's workbooks. It is a general purpose library so you can use it in both WPF and ASP.NET and it can enable you to generate the required excel file from various sources (including from any of those controls)
