WPF tooltip virtualization

Question

Hi! Is there any way to virtualize tooltip in WPF? I have many dataitems displayed on map. When i'm changing template, for example, it takes a lot of time to generate UI for tooltips that are invisible. Maybe wpf supports something for such cind of virtualization? Thanks in advance.

The way in which I've done this before is to generate a tooltip that is very simple, with a container item as the root and a simple single textblock inside, and then hook into the loaded event on the textblock, to detect when the tooltip is trying to be shown.

At that point, I then generate the full tooptip on the fly and replace the contents of the container, removing the textblock placeholder in the process.
