Help with ListGrid and Select Item

[chadcain]

Hi, I have two tables in my oracle database. I created 2 datasources for each table and created a ListGrid which is associated with table 1 (arrivalschedule). It has a column that is a foreign key to table 2 (gate). I want to display the description of the gate, not the id it is associated with, so I need to do a lookup on the gate table. I also want the ListGrid to be editable and want a dropdown of all existing gate descriptions for the user to select. I read other posts but they were of no help to me.
