Thanks. As I said in my reply to Sergey, I had misread the VFP help to indicate that interactive change would not fire in this context.

>>I have taken over maintenance of an application that exclusively uses listboxes (converted from 2.6). I am more accustomed to working with grids. In a grid, when the afterrowcolumnchange event fires, I can refresh other data elements that are adjacent to the grid.

>>How can I accomplish this with a listbox? I see that there is a keypress event, so I could trap for up and down arrow, and others like mousedown. But that seems cumbersome. Is there an event that fires when the row changes or some other way to test for a row change so I can accomplish this?
