Value

Use the Shown event o load controls on the page with the property values for the selected object.

This is most commonly done in the DataInitialize event handler. But using the Shown event instead delays processing until it is actually required by the user.

Depending on the number of custom properties and the type of data, this can be a useful optimization.

The event is a replacement for the OnShow method of the VB6 Extension Designer object.
