Release 10.1A: OpenEdge Development:
Progress Dynamics Administration

Dynamic TreeView optimizations

The dynamic TreeView makes use of dynamic frames to construct the object on the right-hand side, and this helps it to use the object exactly as it was designed. Unlike previous versions, the dynamic TreeView does not replace the toolbar of your object with a generic toolbar. This change affords far more flexibility than in previous versions. In addition, the dynamic frames used by the TreeView can be kept alive, saving time by not having to destroy and re-create them every time a node associated with the frame is reselected. You can configure how these dynamic frames are kept alive.

The dynamic TreeView also supports a node-batching feature that you can configure. If your TreeView object is likely to return a large result set, you can set a maximum number of records to batch, returning subsets of records at one time. If more records are available following the current batch, a …More node is added as the last node allowing the user to get the next batch of records.
