When doing UI programming, having to show a lot of results fast is not uncommon. I recently ran into this show-many-results-fast problem as part of implementing the search functionality for the Element music player. I found that although search results could be computed quickly, getting those results displayed quickly (within a windows store app) was a huge challenge. This post explains the obstacles that make showing a lot of results difficult in windows store apps, and also outlines the solution I ended up using. I’ve also uploaded an example solution to github.
