they only construction when the user clicked on some option.
how to do this?

The old custom visual model provided the Init method and the new custom visuals model provides cosntructor to do the same intiialization work. However, reaching into metadata objects and retrieving custom properties values is usually done in the update method just before rendering.

I guess ou can say that the development model for custom visuals was desgined so developers could acquire custom property values at rending time and not at creation time.
