Using OWC10 to access an Excel file with linked SQL Server
Hello,
I have an Excel spreadsheet with a table in SQL Server as an extenal data source. I am using C# to access this spreadsheet using OWC10 on the web server in an ASP.NET application. The goal is to change a cell's value in Excel through server-side code based on input on a web form, let Excel grab the related data from SQL Server, perform its calculations, and put results in another cell. The server side code would then grab the results from the Excel and display it in the browser. The challenge that I am facing here is that for some strange reason, the data from SQL Server does not get refreshed in Excel. When I use the same spreadsheet in interactive mode (meaning not through server side code), as soon as I change the value in the input cell, the data from SQL Server gets refreshed in the spreadsheet immidiately. I have already tried calling the Refresh, Calculate, and CalculateFull methods on the spreadsheet object -- but no success. Any help will be deeply appreciated. Thank you. |

Using OWC10 to access an Excel file with linked SQL Server
Well, I am disappointed that no one posted any replies to
this. Is this because it's not doable? Am I posting in the wrong newsgoup? Or is it that I am doing something that other people won't usually do?

I can't speak for my colleagues but when I read 4 things (SQL Server, C#, OWC10 and ASP.NET) in the first paragraph about which I know nothing, I decided not to read on as I would be unlikely to know the answer. I guess OWC10 might have something to do with Office Web Components, which are not really a part of Excel.
