How do I auto save individual form control changes to a SQL database?

[Christhemist]

I have a form that exists on a tab control and I want to automatically save any changes "TextChanged" back to the original SQL database. But I just want to save the content of that particular control and not the whole form. I need to do this for all controls on the form, whether it be a checkbox, combo box, text box, etc.

Is there a way to listen for what control is being changed, then updating the SQL database for that particular control?

Note: All controls on the form represent some field in the SQL database. Again, I only want to update the field that corresponds with the control upon any changes.
