Je kan de property bag uitlezen in het ReadProperties event, waarbij het PropBag opject als parameter wordt meegegeven. Buiten dat event bestaat dit object namelijk niet. Zet dus in dit event globale variabelen (of beter: properties binnen jouw classe) met de waarden uit de property bag.

A control on an HTML page is specified using the HTML <OBJECT> and </OBJECT> tags. When the HTML is processed, the control is created and positioned. If the <OBJECT> tag includes any <PARAM NAME> attributes, the property values supplied with those attributes are passed to the control's ReadProperties event using the standard PropertyBag object, as discussed earlier in this topic.
Once the HTML page is active, the control's property values may also be set by scripts attached to events that occur on the page.
Note If there are no <PARAM NAME> attributes other than those that set extender properties, the control may receive an InitProperties event rather than a ReadProperties event. This behavior is dependent on browser implementation, and should not be relied on.
