Summary

A discussion on how to implement a VirtualizingPanel's MeasureOverride method.

Excerpt

"Now that we understand how IItemContainerGenerator works, I’m going to walk through some of the details of how your virtualizing panel’s MeasureOverride should work. I think the easiest way to see how it all works is to just look at some code. In the code below, I’ve excluded the code in MeasureOverride that implements the IScrollInfo stuff. I’m also excluding all of the layout specific code. Basically, it will have to figure out the range of items that are visible based on the scroll position."
