Binding data to a textbox

Hi I am newbie in C#.

I wanted to know how to bind the gui textboxes to a database. Itz like form handling. Once I click the submit button The values that I enter in the textboxes should be updated in the database. Can anyone tell me how We can achieve this. I was just going through the websites but none gave the tutorial regarding this. IF you can give the links to the tutorial that will be appreciated.
The database is access and using OLEDB for that.
Thanks a lot in advance
