How Do I Respond to the End User Movement from One Node to Another? (Magic xpa 4.x)

Sometimes you will want to perform some actions when the user moves from one node to another. This is very easy when you remember that each node in the tree is actually one record in a table. The usual record events ... Record Prefix and Record Suffix ... work just as they do with any other record. The records are simply displayed in a different format.

Capturing movement entering a node

• To capture the movement before the cursor hits a node, put your operations in Record Prefix.

Capturing movement upon leaving a node

• Record Suffix is only executed when the data view is changed.

• If you need to capture the movement in leaving a node when the record is not changed, you will also need to set the Task Properties -> Behavior -> Force Record Suffix flag to Yes.
