How to pass selected row Value to parent window textField?

I'm interested in using the Grid Control to display an LOV (List of Values) for a textfield -the grid control would be a popup window displaying the grid with an OK button. The user would select a row in the grid, click OK and I want the textfield on the parent window to be populated with a particular column of the selected row of the grid.
If anyone has anything like this working I would be extremely grateful for a working example (parent html and popup html with grid control.)
