Link field in table 1 to table 2 and filter

Hi, I'm trying to make it possible for a user to link to a specific record in another table. For example: I have 2 grids set-up. One titled "Parent Directory" and the other titled "Student Directory". Both tables contain a Parent ID which associates the parent with the student. When displaying the Parent ID in the Student Directory grid, I would like to make the Parent ID linkable to the specific Parent Record in the Parent Record Grid. Ideally it would simply grab the student ID and drop that ID into a search filter on the parent directory grid. Make any sense?

Thanks.
