I've created a ListBox to display items in groups, where the groups are wrapped right to left when they can no longer fit within the height of the ListBox's panel. So, the groups would appear similar to this in the listbox, where each group's height is arbitrary (group 1, for instance, is twice as tall as group 2): [ 1 ][ 3 ][ 5 ] [ ]...

This may be a no-brainer for the WPF cognoscenti, but I'd like to know if there's a simple way to put text on the WPF ProgressBar. To me, an empty progress bar looks naked. That's screen real estate that could carry a message about what is in progress, or even just add numbers to the representation. Now, WPF is all about containers and e...
