property OnRender: TNotifyEvent; (this event is defined in the class TIWContainer)

 

This event is triggered just before the IntraWeb rendering mechanism starts rendering the form. Use this event to make any special processing, user interface updates, etc.

 

Remember this event is triggered every time there is a full post event on your form, like a Button click and you need to be carefull on which code you add to this event. If you open a dataset on this event, it may slow down your form rendering process.
