I am very new to oracle. I was able to install it and was trying the tutorial:
Building .NET Applications Using Oracle Developer Tools for Visual Studio. I am using Windows XP sp3 and Visual Studio 2008 Professional.

I was working on the tutorial that came with the Oracle Data Access Components (ODAC)ODAC 11g 11.1.0.6.21

I was following the C# example that came with the tutorial. Whenever I modify the table and click on the Save Button, I get the error below:

TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance.

Does anyone knows how to solve this problem?

What am I doing wrong. Please Help
