Help with binding textbox to combobox

Question

I have a relatively large no. of textboxes and I need to perform an action whereby when a user say clicks on textbox2, the item of combobox2 will also be loaded

E.g. When I click on textbox2, another form will load and the contents to be display is from combobox2. If it's textbox3 then combobox3...etc

Can I use Access database to do it since later I will need the values of the textboxes and combobox to be permanent.

Thanks!
