DataCombo and Form

I'd like to have a form that displays fields from a record based on what the user selects from a datacombo box on the same form. In other words, when the form first appears all the fields would be populated with the first record. If, from the datacombo the user selects a customer name which is the 15th record the form would be updated and show that record. Can anyone steer me towards an example. Thanks
