help in Dataset using Ms Access

hi, i have windows form in vb.net that has textboxes binded already to the dataadapter. When i run my form the record appears in the binded controls. Now what i want to do is search for a specific record using the "studno" field in my "grade" table in my "db6" database. Then when i find the record i want it displayed in the textboxes on my form. is this possible?
Thank u for your help in advance.
It would be great if you could show me an example and of course the code.
