>This is a Visual Interdev 6.0 question, thought I would give it a shot........When my onChange event fires for my listbox DTC, it seems to refresh the entire page, Re-running all server side code. Is this normal behavior? If not, what can I do so only the onChange code fires when a user changes the value of the listbox?

Well... it depends on what you are looking for. You can have the code run at the client side, but then the client will also need a connection to the data, or you can use RDS to pass the data as a disconnected recordset.
