Data not getting saved in Sql server

Hi,
I am trying to use the dataconnector in asp.net web application. Attached is my sample code. There is no error. I put a break point in the gcdbconnector.ashx.cs and the debugger hits that breakpoint without any error. However the data is not getting saved into the database. Please let me know what is the issue in my code.

Thanks

Hello,
the code looks correct. Can you attach a complete sample where we could test data saving?
