Binding Textboxes and Combo's

Question

I'm developing a windows application and I have one form that consists of a datagridview that populates data from a database. I want to be able to select a row (w/ the grdCarrierMaint_CellContentClick event) and have a seperate form start up with each column of the selected row, populated into individual controls(ie textboxes). I want to do this so I can edit the data and i realize that I can edit right from the datagridview, but there is other functionality that i need to include on this modal form. Can anyone tell me how i can pass in data from a gridview to these individual controls?
