Now preserving column widths for the three DataGrids and the main ListView. In theory the various grids would conveniently auto-size to the content, but in practice that doesn't work well with virtualization. There is, of course, no simple "the width has changed" event provided by the control. On the plus side, you can attach a property-change event handler to pretty much anything, so once you know the trick it's possible to make everything work. Yay WPF.
