One thing to note…. I drive the population of the grid from the DB. When changes occur to the DB, and if a grid needs to be updated it is updated. If I need to update a row in the Grid with a script, I update the DB, that in turn updates the correct row in the Grid. Therefor the only changes that I need to listen for on the grid are user edits. I *think* i can get what I want with this. on CloseFieldEditor put the dgControl of the target into theGrid send "DataGridEdited theGrid" to me in 1 millisecond end CloseFieldEditor on DataGridEdited theGrid -- grab the data and store it. -- since I have a reference to the grid I can get its data. end DataGridEdited Or this is where I am at so far…. The "send" to me in 1 millisecond is key. Since that is what allows the Field editor to close. I think I will be able to get what I need from the grids to automatically save the data, but I don't think it is going to help you, Monte :-(. You probably need a message on any change to the data in a grid regardless of how it is made. I only care about user edits.
