Newbie Question - sorry if it is really basic!

I have managed to get the AW grid working in it's own page with my data. In my app the user is presented with a screen of data fields, some of which are coded lists. Beside these coded fields I want a button which will open up a popup screen containing the page with the AW grid.

If the data field has an entry already, I would like the grid to have that record selected as default.

I would like the user to be able to double click on an entry in the grid, and the code selected to be carried back to the data page.

Anyone? Your help is appreciated. Love the grid!
