More specifically, I tried having a grid of 48 rows, 40 units high, contained in a scroll viewer... each row was to contain a progress bar, but for whatever reason, this really REALLY slowed down my user interface, so I've scrapped it. My questions are as follows:
Why would the progress bar cause such extreme slowdown, especially while the host panel is animating?
In place of a progress bar, I could use a multi-coulumn grid and fill it with rects that change size and can be individually colored, would this be a "faster" solution?
